Background
The process of wound healing has overlapping phases (coagulation, inflammation and proliferation/remodeling phases) in which the composition of the local microenvironment changes over time, with different cell types playing different roles. Key cellular participants in the healing process are platelets, keratinocytes/epithelial cells, fibroblasts/myofibroblasts, different immune cells and endothelial cells. All tissues in the body may be injured and the healing process is somewhat specific to the organ, but the initial signals caused by damaged cells are similar. The wound healing form of greatest interest is on the skin.
Tissue damage disrupts homeostasis, initiates the coagulation process and activates the sympathetic nervous system. Platelet release signals for clot formation, mainly PDGF (platelet derived growth factor) and TGF (transforming growth factor), alter the local environment (see document 1). The injured and stressed cells release an alarm signal that triggers the recruitment of immune cells such as neutrophils and monocytes. Within the wound tissue, immune cells secrete various chemokines, growth factors such as VEGF-A, FGF and EGF (vascular endothelial growth factor a, fibroblast growth factor, epidermal growth factor), ROS (reactive oxygen species) and matrix digestive enzymes, which alter the microenvironment and allow the healing process to enter the proliferative phase where macrophages remove necrotic and dead tissue. Cells from the wound margins, such as fibroblasts and keratinocytes, migrate inward to the center of the wound and cover the wound surface with a layer of collagen and extracellular matrix. Fibroblasts within the wound are then transformed into myofibroblasts expressing contractile alpha-SMA (alpha-smooth muscle actin), causing the wound to contract and eventually close. The transition from fibroblasts to myofibroblasts depends on signals from the microenvironment, some of which are derived from immune cells, mainly macrophages. In this process, blood vessels grow to form newly formed tissue, granulation tissue. In addition to immune cell recruitment and migration to the site of the lesion, blood flow to adjacent areas is often increased at this stage to increase the availability of oxygen and nutrients.
After wound closure, the lesion is re-epithelialized by keratinocytes/epithelial cells, thereby restoring the integrity of the organ barrier. Even after wound closure, some tissue remodeling occurs to normalize the matrix structure, and most of the immune cells involved die or leave the site. In addition, at this stage, dead or dying cells are taken up and cleared (phagocytosed) by the remaining tissue macrophages (reference 1). Faster wound healing alleviates complications and discomfort for the patient.
Wounded or delayed skin or mucosal wound healing is a global clinical problem that leads to pain, direct exposure to pathogens, loss of tissue function, and loss of temperature and fluid balance regulation. There are several situations in which a tightly controlled wound healing process is impaired and skin or mucosal wounds remain unhealed for longer than normal, and in the worst case become chronic.
Reducing blood flow to the skin, particularly at the extremities, significantly reduces the efficiency of the healing process. Several clinical situations with reduced skin perfusion or impaired vascular system function such as PAD (peripheral arterial disease), intermittent claudication, venous insufficiency or vascular occlusion of arteriosclerotic plaques. Impaired blood flow to the wound area results in oxygen and nutrient starvation, and cells that assist tissue reconstruction die from necrosis or the inability to perform tasks at the site. Furthermore, if not adequately supplied, the surrounding tissue will fail and eventually begin to die. The tissue is very metabolically active during the remodeling stage and oxygen consumption is high.
Another factor that interferes with the healing of skin wounds is hyperglycemia and diabetes. Under hyperglycemic conditions, cell signaling and immune system function are impaired. Complications resulting from diabetes include microvascular changes and damage to peripheral neurons. Therefore, diabetics often develop chronic wounds on the feet, commonly referred to as diabetic feet. The treatment available today for these patients is surgical debridement or collagenase to remove dead tissue in conjunction with systemic antibiotic therapy and wound closure dressings. In some experimental studies, growth factors and biomaterials have been applied to chronic wounds (reference 2).
Stromal cell derived factor 1(SDF-1), also known as C-X-C motif chemokine 12(CXCL12), is a chemokine protein encoded in the body by the CXCL12 gene. WO2009/079451 discloses a method for promoting wound healing in a subject comprising administering SDF-1 directly to the wound or an area proximate to the wound in an amount effective to promote wound healing in the subject.
It has been demonstrated that wound healing can be promoted if certain probiotics (Lactobacillus reuteri ATCC PTA 6475) are supplemented in the drinking water during the healing process (reference 9), i.e. bacteria are ingested. Furthermore, the supernatant of a culture of Lactobacillus plantarum (Lactobacillus plantarum) has been shown to inhibit biofilm production by Pseudomonas aeruginosa (Pseudomonas aeruginosa) which normally infects chronic wounds (reference 10).
It has surprisingly been found that lactic acid bacteria modified according to the invention to express specific proteins (e.g. cytokines) can be used to promote wound healing. Lactic acid bacteria are sparsely present on human skin (reference 13) and are not the intended choice of bacteria for any intervention in the skin. Lactobacillus (lactobacillus) are difficult to work because they grow relatively slowly and require special media and conditions compared to more commonly used bacteria such as e.coli and s.aureus. In addition, lactobacilli have limited intracellular mechanisms for transcription, translation, and protein folding. For this reason, it is necessary to optimize the nucleotide sequence encoding the heterologous protein to suit the specific bacterial strain.
The different stages of wound healing include different key events that can be varied to alter the healing process. Vascular remodeling during healing is highly dependent on the induction of hypoxia inducible factor 1 alpha (HIF-1 alpha) that regulates the expression of VEGF-A (vascular endothelial growth factor A) and a range of chemokines, such as CXCL12 (also known as SDF-1; SEQ ID NOS: 3 and 6). CXCL12 is constitutively expressed in tissues and plays a role in inducing various cell behaviors through the receptor CXCR4 found on leukocytes and endothelial cells (reference 3). CXCL12 was found to have high levels in macrophages dedicated to tissue remodeling (reference 4). Cutaneous overexpression of CXCL12 using lentiviral vectors improved wound healing in diabetic mice (see document 5).
Another recently discovered chemokine is CXCL17(SEQ ID NOs: 9 and 12), which has a similar effect on the phenotype of tissue macrophages as CXCL 12. Similar to CXCL12, CXCL17 co-regulates VEGF-a measured in cell culture (reference 6). CXCL17 was mainly found in mucosal tissues and was reported to have a direct antibacterial effect against pathogenic bacteria also found on the skin, but had no effect on the survival of Lactobacillus casei (ref 7).
Another protein of interest is the chitinase-like protein Ym1(SEQ ID NO: 15 and 18). Chitin is a common polysaccharide in bacterial biofilms. Ym1 is capable of both preventing biofilm formation and inducing macrophage functions important for tissue remodeling and wound healing, and is specific for macrophages because it is not absorbed by vascular or epithelial cells (see document 8).
Disclosure of Invention
Thus, in a first aspect, the present invention provides a recombinant plasmid capable of expressing a protein in a lactic acid bacterium (i.e. when transformed into a lactic acid bacterial cell), wherein the protein is useful for improving wound healing, for example skin or mucosal wound healing, in a human or animal subject. Preferably, the protein is useful for wound healing due to its ability to target immune cells such as macrophages and their precursors. Preferably, the protein is a cytokine or chemokine. Most preferably, the protein is selected from the group consisting of murine CXCL12, particularly murine CXCL12-1 alpha (SEQ ID NO: 3); human CXCL12, particularly human CXCL12-1 α (SEQ ID NO: 6); murine CXCL17(SEQ ID NO: 9); human CXCL17(SEQ ID NO: 12); murine Ym1(SEQ ID NO: 15); and human Ym1(SEQ ID NO: 18).
The first aspect of the invention more particularly provides a plasmid capable of expressing a recombinant protein in a lactic acid bacterium (i.e. when transformed into a lactic acid bacterium cell), wherein said plasmid comprises a nucleotide sequence encoding a protein selected from CXCL12, CXCL17 and Ym 1.
More specifically, the nucleotide sequence may encode murine CXCL12, particularly murine CXCL12-1 α; human CXCL12, in particular human CXCL12-1 α; murine CXCL 17; human CXCL 17; murine Ym 1; or human Ym 1.
In one embodiment, the plasmid comprises a nucleotide sequence encoding a protein selected from the group consisting of a polypeptide having the amino acid sequence of SEQ ID NO: 3 or 2 or an amino acid sequence having at least 80% sequence identity thereto; has the sequence shown in SEQ ID NO: 6 or 5 or an amino acid sequence having at least 80% sequence identity thereto; has the sequence shown in SEQ ID NO: 9 or 8 or an amino acid sequence having at least 80% sequence identity thereto; has the sequence shown in SEQ ID NO: 12 or 11 or an amino acid sequence having at least 80% sequence identity thereto; has the sequence shown in SEQ ID NO: 15 or 14 or an amino acid sequence having at least 80% sequence identity thereto; and as shown in SEQ ID NO: 18 or 17 or an amino acid sequence having at least 80% sequence identity thereto.
More specifically, plasmids are used to express proteins in lactic acid bacteria, and thus provide or adapt for such use (e.g., they are designed, selected, adapted or modified for specific or particular use in lactic acid bacteria). Thus, in one embodiment, the plasmid is used for specific expression in lactic acid bacteria relative to bacteria or microorganisms in general. The plasmid may be suitable for expression in lactic acid bacteria by regulatory elements (regulatory sequences) and/or coding sequences, e.g. selected or modified for expression in lactic acid bacteria.
Thus, in a more specific aspect, the plasmid comprises one or more regulatory (i.e. expression control) sequences that allow expression or specific expression in a lactic acid bacterium. Thus, the plasmid may contain expression control sequences derived from or suitable for or specific for expression in lactic acid bacteria. Suitable expression control sequences include, for example, translation (e.g., start and stop codons, ribosome binding sites) and transcriptional control elements (e.g., promoter-operator regions, termination stop sequences) linked in matching reading frames to a nucleotide sequence encoding the protein to be expressed. The regulatory sequences are operably linked to the nucleotide sequence encoding the protein such that they drive or control the expression of the protein. The plasmid may be introduced into a lactic acid bacterial cell. Suitable transformation techniques are well described in the literature. Bacterial cells can be cultured or otherwise maintained under conditions that allow expression of the protein from the plasmid. This may include a condition in a wound of the subject.
In one embodiment, the promoter in the plasmid controlling the expression of the protein is a promoter that allows or is specific for expression in lactic acid bacteria. Thus, the plasmid may comprise a nucleotide sequence encoding a protein under the control of (or operably linked to) a promoter capable of expressing the protein in a lactic acid bacterium. In a particularly preferred embodiment, the plasmid comprises a lactic acid bacterium promoter, i.e. the promoter controlling the expression of the protein is a promoter derived from a lactic acid bacterium, or more particularly a gene obtained or derived from expression in a lactic acid bacterium.
In some embodiments, the plasmid may comprise, in addition to the lactic acid bacteria promoter, other regulatory elements or sequences that control the expression of proteins obtained from or derived from lactic acid bacteria. Thus, for example, such other lactic acid bacterial cell expression control elements or sequences may include enhancers, terminators and/or translation control elements or sequences as described above. In some embodiments, the plasmid may further comprise regulatory elements or sequences that control or regulate expression from a promoter, e.g., operator sequences and the like or one or more regulatory genes as discussed further below.
Alternatively or additionally, the plasmid may be adapted (or modified, etc.) for use in lactic acid bacteria by codon optimization of the nucleotide sequence encoding the protein for expression in lactic acid bacteria.
In a preferred embodiment, the promoter used for expression of the protein is a regulated (regulatable) or inducible promoter. Thus, by providing or contacting the bacterium with a regulatory molecule or inducer that activates or initiates (induces) the promoter, expression of the protein can be controlled or regulated (e.g., elicited, as desired or at an appropriate time). This is advantageous in the case of protein delivery to a wound.
Thus, a further aspect of the invention provides an expression system for expressing a protein in a lactic acid bacterium, said expression system comprising (i) a plasmid as defined herein, wherein said plasmid comprises a nucleotide sequence encoding said protein under the control of an inducible promoter, said plasmid being capable of expressing said protein in a lactic acid bacterium; and (ii) an inducer (or regulatory molecule) for the promoter. The expression system may conveniently be provided in the form of a kit comprising components (i) and (ii) as described above.
Another aspect of the invention is a bacterium (bacterium) or bacterium (bacteria) (i.e. bacterial cell or strain) transformed (i.e. comprising) with a plasmid of the invention as defined herein. In particular, the bacterium is a lactic acid bacterium, and thus the present invention provides a lactic acid bacterium (or lactic acid bacterium) comprising a plasmid of the invention as defined herein. Alternatively expressed, this aspect of the invention provides a bacterium (or bacterial cell) into which a plasmid of the invention has been introduced.
As further described herein, the plasmids and bacteria of the present invention are useful for promoting healing, and thus have particular utility in promoting wound healing, defined herein as wounds generally comprising damaged tissue (see below). Thus, a further aspect of the invention provides the use of such plasmids and bacteria in therapy, more particularly in wound healing.
The bacteria may be administered to a wound of a subject to be treated in the form of a pharmaceutical composition. Thus, another aspect of the present invention provides a pharmaceutical composition comprising a bacterium of the invention as defined herein and at least one pharmaceutically acceptable carrier or excipient.
More generally, the present invention provides probiotic products comprising the bacteria of the present invention.
Such products or pharmaceutical compositions may conveniently take the form of wound dressings comprising the bacteria of the present invention.

the pharmaceutical products are for separate, sequential or simultaneous use in wound healing (or for treating a wound in a subject) as a combined preparation.
The term "wound healing" is used broadly herein to include any aspect of promoting or improving wound healing. Thus, the various aspects of the invention set out above may alternatively be defined in relation to the use of a plasmid or bacterium in promoting or enhancing or improving wound healing or simply in promoting or enhancing healing.
Thus, wound healing may include or include any effect that results in faster wound healing or more complete healing of the wound, or even any improvement or improvement in wound healing, such as a reduction in healing time, e.g., a reduction in the time to achieve partial or complete closure of the wound, an improvement in wound appearance (e.g., the appearance of a healed or healing wound), a reduction or improvement in scarring, promotion of chronic or refractory wound healing, etc. (i.e., application of the bacteria of the present invention to a wound may induce or cause or initiate healing of the wound, which has not yet healed or has not yet developed any signs of healing). Wounds will be discussed in more detail below.
The subject having a wound to be treated may be any human or animal subject, including for example domestic animals, livestock, laboratory animals, sport animals (sport animals) or zoo animals. The animal is preferably a mammal, but also includes other animals, e.g., birds. Thus, the animal may be a primate, rodent (e.g., mouse or rat), or horse, dog or cat. Most preferably the subject is a human.
Lactic Acid Bacteria (LAB) or lactobacilli (lactobacilli) are branches of gram-positive, low-GC, acid-tolerant, generally non-sporulating, non-respiratory, rod-shaped (bacillus) or coccoid (coccus) bacteria with common metabolic and physiological characteristics. These bacteria produce lactic acid as the main metabolic end product of carbohydrate fermentation, which is characterized by an increased acid resistance (low pH range). These characteristics of LAB allow them to be superior to other bacteria in natural fermentation, as LAB can withstand increased acidity from organic acid production (e.g. lactic acid). LAB therefore plays an important role in food fermentation, as acidification inhibits the growth of spoilage agents. Several LAB strains also produce protein bacteriocins, which further inhibit spoilage and growth of pathogenic microorganisms. LAB is generally recognized as a safe (GRAS) state and is one of the most important microbial populations employed in the food industry.
The core genera containing the branching of lactic acid bacteria are Lactobacillus (Lactobacillus), Leuconostoc (Leuconostoc), Pediococcus (Pediococcus), Lactococcus (Lactococcus), and Streptococcus (Streptococcus), and also more peripheral Aerococcus (Aerococcus), Carnobacterium (Carnobacterium), Enterococcus (Enterococcus), Oenococcus (Oenococcus), Lactobacillus (Sporolactis), Tetragenococcus (Tetragenococcus), Vagococcus (Vagococcus), and Weissella (Weissella). Any lactic acid bacteria of these genera are included within the scope of the present invention, in particular bacteria from the genera Lactobacillus (Lactobacillus) or Lactococcus (Lactococcus).
The plasmid may encode one or more of said proteins. Thus, it may encode a combination of CXCL12, CXCL17, and/or Ym1 proteins (e.g., 2 or more of CXCL12, CXCL17, or Ym 1). Alternatively, it may encode 2 or more types of CXCL12, CXCL17 and/or Ym1 proteins (e.g., murine and human CXCL12, etc.). When more than one protein is encoded, the protein may be expressed from the nucleotide sequence encoding the protein under the control of a single promoter, or more than one promoter may be used. For example, each protein may be expressed from a separate promoter, which may be the same or different. Techniques for expressing 2 or more proteins together from the same plasmid are well known in the art and include, for example, translational coupling techniques and the like, means for achieving this are known and available in the art. For example, multiple transgenes can be expressed simultaneously under one promoter using the P2A and T2A sequences.
The CXCL12, CXCL17, or Ym1 proteins can be natural or native proteins (i.e., the nucleotide sequence can encode a protein having an amino acid sequence found in nature), and can be from any substance that produces these proteins. Typically, the protein will be a mammalian protein, and as noted above, human and murine proteins are preferred. However, the native nucleotide sequence or protein sequence may be modified, for example by one or more amino acid additions, insertions, deletions and/or substitutions, as long as the function or activity of the protein is not substantially or significantly altered, for example, as long as the activity of the protein is substantially retained. The protein may be a fragment or a truncated variant of the native protein. For example, a sequence modified variant protein may exhibit at least 80%, 85%, 90%, or 95% of the activity of the parent protein from which it is derived. This can be assessed according to assays known in the art for the activity of the above proteins. For example, activity assays can be performed in a system of receptor phosphorylation or calcium flux in culture cells treated with the protein after ligation, in a system of chemotaxis in vitro or in vivo of cells in a model of cell recruitment of the infected protein. In vitro chemotaxis-based assays are described in references 22 and 32. Reference 33 describes additional in vitro chemokine activity assays that may be employed. Thus, the terms "CXCL 12", "CXCL 17" or "Ym 1" include not only native proteins but also their functionally equivalent variants or derivatives. Thus, a protein may be a synthetic or sequence-modified variant, or may include one or more other modifications, e.g., post-translational modifications, etc.
As mentioned above, the encoded protein may have the amino acid sequence of a native human or murine protein as described above, i.e. SEQ ID NO: 3 and 6 are murine and human CXCL12, 9 and 12 are murine and human CXCL17, 15 and 18 are murine and human Ym1, respectively, or an amino acid sequence having at least 80% sequence identity to any of the foregoing sequences. Advantageously, as described above, the nucleotide sequences encoding these native proteins may be codon optimized for expression in lactic acid bacteria. This can result in encoded proteins with modified amino acid sequences. For example, a codon optimized sequence may encode a sequence, such as a secretory sequence suitable (or more suitable) for a lactic acid bacterium. Thus, an "optimized" protein encoded by a codon optimized nucleotide sequence may include altered or substituted leader or signal sequences (e.g., secretory sequences) as compared to the native protein. In a preferred embodiment, the mature or cleaved form of the protein encoded by the codon optimized sequence is identical to the native protein. The protein encoded by the codon-optimized nucleotide sequence may have the sequence as set forth in SEQ ID NO: 2. 5, 8, 11, 14 or 17, as set forth in table IV below. Thus, the protein encoded by the plasmid may have the sequence as set forth in SEQ ID NO:2 and 5 are the amino acid sequences of murine and human CXCL12, respectively, 8 and 11 are murine and human CXCL17, respectively, and 14 and 17 are murine and human Ym1, respectively, or an amino acid sequence having at least 80% sequence identity to any of the foregoing sequences.
In other embodiments, the encoded protein may have an amino acid sequence that has at least 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, or 99% sequence identity to any of the above amino acid sequences.
Sequence identity can be readily determined by methods and software known and readily available in the art. Thus, sequence identity may be assessed by any convenient method. However, in order to determine the degree of sequence identity between sequences, computer programs that perform multiple alignments of sequences are useful, for example Clustal W (reference 24). Programs that compare and ALIGN pairs of sequences, such as ALIGN (ref 25), FASTA (ref 26 and ref 27), BLAST and gapped BLAST (ref 28) can also be used for this purpose, and default settings can be employed. In addition, the Dali server of the european bioinformatics institute provides structure-based protein sequence alignments (ref 29, ref 30 and ref 31). Multiple sequence alignments and percent identity calculations can be determined using standard BLAST parameters (e.g., using sequences from all available organisms, matrix Blosum62, gap cost: present 11, extension 1). Alternatively, the following procedures and parameters may be employed: the procedure is as follows: align Plus 4, version 4.10(Sci Ed Central Clone Manager Professional Suite). DNA comparison: global comparison, standard linear scoring matrix, mismatch penalty of 2, open gap penalty of 4, and extended gap penalty of 1. Amino acid comparison: global comparison, BLOSUM62 scoring matrix.
Variants of a naturally occurring polypeptide sequence as defined herein may be generated synthetically, for example by employing standard molecular biology techniques known in the art, for example standard mutagenesis techniques such as site-directed or random mutagenesis (for example employing shuffling or error-prone PCR).
Derivatives of the proteins defined herein may also be encoded. Derivative refers to a protein as described above or a variant thereof, wherein the amino acids are chemically modified, e.g. by glycosylation or the like.
When the protein comprises amino acid substitutions relative to the sequence of the native protein, the substitutions may preferably be conservative substitutions. The term "conservative amino acid substitution" refers to any amino acid substitution in which an amino acid is replaced (substituted) by an amino acid having similar physicochemical properties (i.e., amino acids of the same class/group). For example, the small residues glycine (G), alanine (a), serine (S) or threonine (T); the hydrophobic or aliphatic residues leucine (L), isoleucine (I); valine (V) or methionine (M); the hydrophilic residues asparagine (N) and glutamine (Q); the acidic residues aspartic acid (D) and glutamic acid (E); arginine (R), lysine (K), or histidine (H) with positively charged (basic) residues; or the aromatic residues phenylalanine (F), tyrosine (Y) and tryptophan (W)) may be interchangeably substituted without substantially altering the function or activity of the protein.
As described above, it is preferable to express a protein using an inducible promoter. "inducible" refers to any promoter whose function (i.e., the activity or action that allows or causes transcription of an encoding nucleotide sequence) can be regulated or controlled. The term "inducible" is therefore synonymous and can be used interchangeably with "controllable" (or "regulated"). Thus, there is no constitutive expression of the protein. Thus, expression of the protein may be induced or initiated (or more particularly initiated and switched off). More specifically, expression may be induced or initiated within a limited or defined time. This may be because expression ceases after a period of time, and/or because bacterial cells die.
In some embodiments, there may be no expression (transcription) from the promoter until the promoter is induced (or alternatively referred to as activated). However, as with any biological system, lack of activity may not be absolute, and some basal promoter activity may be present in the absence of promoter activation or induction. However, in preferred embodiments, any basal expression of the non-inducible promoter is low, minimal or insignificant, or more preferably, trace or negligible. Thus, expression from an inducible promoter is advantageously measurable or significantly increased when the promoter is induced compared to when the promoter is not induced.
Inducible promoters are well known in the art, including inducible promoters for use in lactic acid bacteria, and any suitable inducible promoter suitable for expression in lactic acid bacteria may be used.
Inducible promoters may be induced (or activated) in the presence of an inducer or activator molecule, which may act directly or indirectly on the promoter and may be added to induce the promoter, or more generally to cause or effect promoter induction or activation and allow expression of the protein, or may be induced (or activated) by a change in the conditions of the plasmid-containing bacterium, for example by introducing a change in conditions in the lactic acid bacterium, for example starvation or consumption of a particular nutrient. The inducer of the promoter may be encoded by a regulatory gene, which itself may be induced or activated in one embodiment. Thus, the term "inducing agent" is used broadly herein to include any regulatory molecule, or indeed any permissive condition, that can activate or initiate an inducible promoter, or that allows or causes an inducible promoter to be induced. Thus, induction of an inducible promoter may include introduction (e.g., contact with a lactic acid bacterium comprising a plasmid) of a regulatory molecule or conditions that allow induction (activation) of the promoter. In some embodiments, the inducing agent may be an activating peptide. This may induce the promoter directly or indirectly, e.g., as described further below.
As described above, promoters obtained or derived from lactic acid bacteria are preferred. These may be natural promoters or modified or mutated promoters. Suitable promoters may be identified, for example, by growing lactic acid bacteria in a wound and by determining which genes are expressed or upregulated in the bacteria in the wound. Promoters from these genes can then be identified. Alternatively, many different promoters and expression systems in or for lactic acid bacteria have been identified and described or are available in the art, including expression plasmids containing such promoters or expression systems for LAB. Any such known plasmid or expression system can be used as the basis for the recombinant plasmid of the present invention.
Various inducible expression systems are known in the art for LAB such as lactobacillus. One example includes an auto-inducible system based on the manganese starvation inducible promoter of the manganese transporter of lactobacillus plantarum (l.plantarum) NC8 described in reference 19. This system does not require the addition of an external inducer for recombinant protein production.
Duong et al (reference 20) describe expression vectors based on a wide range of pWV01 replicon lactobacilli and contain promoters from operons involved in Fructooligosaccharide (FOS), lactose or trehalose metabolism or transport or glycolysis. Such promoters can be induced by their specific carbohydrates and inhibited by glucose.
More specifically, the inducible expression system may comprise an inducible promoter involved in the production of LAB proteins, in particular bacteriocins. The activity of such a promoter can be controlled by a homologous regulatory system based on bacteriocin regulators, such as a two-component regulatory (signal transduction) system which responds to externally added activation peptides (i.e.inducers/regulatory molecules in the form of peptides) and genes encoding the histidine protein kinase and responsive regulatory factors required for activating the promoter after induction by the activation peptides.
In one embodiment, the expression system may be based on the nisin controlled expression (NICE) system, based on a combination of the nisA promoter and nisRK regulatory genes. This system is based on promoters and regulatory genes from the lactopeptin gene cluster of Lactococcus lactis (Lactococcus lactis) and has been used to develop regulatory gene expression systems for Lactococcus lactis (Lactococcus), lactobacillus and other gram-positive bacteria (briefly described in references 15 and 21). While NICE systems are highly efficient and well regulated in lactococcus lactis, these systems can exhibit significant basal activity. This can be circumvented by limiting the expression system to a specifically designed host strain by integrating histidine kinase and response regulatory genes into the chromosome.
In another embodiment, the expression system may be based on a gene and promoter involved in the production of the class II bacteriocin sakacin A (sap gene) from the sakacin A regulator or sakacin P (spp gene) from the sakacin P regulator. Such a vector is called a pSIP vector, contains a promoter element derived from a structural gene of sakacin A or sakacin P, and has an engineered NcoI site for translational fusion cloning. Various such vectors containing different promoters from regulators and/or different replicons are described in references 21 and 15, and any of these vectors can be used as the basis for the recombinant plasmids of the present invention.
In representative embodiments, the promoter may be P from sakacin A or P regulonsapA、PsppAOr PorfXA promoter, and a regulatory gene related or homologous thereto.
In a particularly preferred embodiment, the plasmid contains the pSH71 replicon, P from the sakacin P regulator, based on the vector pSIP411 shown in FIG. 12 and described in reference 21orfXPromoters and homologous regulatory genes. Plasmid pSIP411 is designated in this application as pLAB 112. The inducer used in such embodiments is preferably an activating peptide based on the peptide SppIP, e.g. having the sequence of SEQ ID NO: 19 or an amino acid sequence having at least 80% (or more particularly at least 85, 90 or 95) sequence identity thereto. In a preferred embodiment, the recombinant plasmid is derived from a plasmid having the sequence of SEQ ID NO:20, designated pllab 112.
The use of inducible promoters (or inducible expression systems) may provide the advantage of more controlled, in particular prolonged, protein expression in the wound environment, i.e. when the bacteria are administered to a subject or wound. For better efficacy in promoting wound healing, it is advantageous to express the protein at the wound site (e.g. wound surface) using bacteria for a period of time, for example at least 40, 45, 50, 55 or 60 minutes, in particular at least 1 hour or more. Thus, proteins may be expressed for a limited, defined or extended period of time. The results presented in the examples below show that with the plasmids and bacteria according to the invention, proteins can be expressed on the wound surface for a period of about 1 hour. In some embodiments, plasmids and bacteria may be optimized to allow for protein expression (e.g., in a wound) for 2, 3, or4 hours or more.
Thus, continuous expression and delivery of proteins is desirable, and this can be provided by using the transformed bacteria of the present invention. By "continuous" or "extended" is meant that there is protein expression, and thus protein delivery, over a period of time, such as over a period of at least one hour (or similarly, as described above). In particular, this allows the protein to be more effective over a period of time than if the protein was administered directly (i.e. as a protein product rather than expressed by the bacteria).
As described above, the nucleotide sequence encoding the protein may be codon optimized for expression in LAB. Thus, in a preferred embodiment, the nucleotide sequence (or insert) encoding the protein in the recombinant plasmid may be selected from the group consisting of SEQ ID NO: 1.4, 7, 10, 13 and 16, which encode murine CXCL12, human CXCL12, murine CXCL17, human CXCL17, murine Ym1 and human Ym1, respectively, or nucleotide sequences having at least 80% sequence identity thereto.
Thus, in representative embodiments, the recombinant plasmid may be selected from the group consisting of: a plasmid designated mLrCK1 comprising the sequence set forth in SEQ ID NO: 1; mlrck1.4 comprising SEQ ID NO: 1; mlrck1.7 comprising SEQ ID NO: 1; hLrCK1 comprising SEQ ID NO: 4; mLrCK2 comprising SEQ ID NO: 7; hLrCK2 comprising SEQ ID NO: 10; hLrMP1 comprising SEQ ID NO: 13, or a nucleotide sequence shown in seq id no; and mLrMP2 comprising the amino acid sequence set forth in SEQ ID NO: 16.
In some embodiments, the plasmids of the invention comprise a codon-optimized insert mLrCK1 (i.e., the nucleotide sequence of SEQ ID NO: 1), mLrCK1.4 (i.e., the nucleotide sequence of SEQ ID NO: 1), mLrCK1.7 (i.e., the nucleotide sequence of SEQ ID NO: 1), hLrCK1 (i.e., the nucleotide sequence of SEQ ID NO: 4), mLrCK2 (i.e., the nucleotide sequence of SEQ ID NO: 7), hLrCK2 (i.e., the nucleotide sequence of SEQ ID NO: 10), hLrMP1 (i.e., the nucleotide sequence of SEQ ID NO: 13), and mLMP 2 (i.e., the nucleotide sequence of SEQ ID NO: 16) having a nucleotide sequence of at least 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, or 99% sequence identity.
The sequence identity of a nucleotide molecule can be determined by methods and software known and widely available in the art, for example by using a FASTA search with the GCG package with default values and variable pam factors (pamfactor), and a gap creation penalty set at 12.0 and a gap extension penalty set at 4.0 (window of 6 nucleotides).
Related nucleotide sequences of such sequence identity may be functionally equivalent to SEQ ID NO: 1.4, 10, 13 or 16. These nucleotide sequences may be considered functionally equivalent if they encode a polypeptide which would be considered a functional equivalent to the corresponding CXCL12, CXCL17 or Ym1 protein. Preferred functional equivalents are those which encode the preferred proteins as described above.
In another aspect, the present invention provides a bacterial strain transformed with the above recombinant plasmid. The bacterial strain is preferably a lactic acid bacterial strain such as a Lactobacillus strain or a lactococcus (e.g. lactococcus lactis) strain. More preferably, the bacterial strain is lactobacillus reuteri, such as lactobacillus reuteri R2LC or lactobacillus reuteri DSM 20016. The strains (Lactobacillus reuteri R2LC/DSM20016 and lactococcus lactis) were not found on human skin as determined by phylogenetic analysis of the forearm skin flora of six subjects (reference 13).
In addition to plasmids, expression systems, bacteria and kits, additional products of the invention include pharmaceutical compositions and medical devices comprising bacteria. Such compositions and devices may include, inter alia, wound dressings, packaging materials, swabs, implants, etc., or even any medical device, such as a wire or catheter or implant, that may be introduced or present at a wound site (e.g., at a surgical wound site), either wholly or partially inherent. Also included are probiotic products, i.e. products containing bacteria for administration to a subject, e.g. for oral administration, e.g. for consumption or ingestion, or topical application to a wound or direct application to the wound site, e.g. during surgery, or rectal, vaginal routes, etc.
Thus, the products according to the invention (e.g. plasmids, bacterial strains, probiotics, wound dressings, etc.) may be used in medical therapy, in particular for promoting wound healing in a human or animal subject. As used herein, the term "promoting wound healing" refers to enhancing, ameliorating, increasing, or inducing closure, healing, or repair of a wound. In a preferred aspect of the invention, the human or animal subject is in need of wound healing due to an underlying medical condition resulting in impaired wound healing, such as reduced peripheral blood perfusion (peripheral arterial disease), hyperglycemia or neuropathy, or the subject may be immunocompromised for any reason, such as due to an underlying disease (whether acquired or inherited) or as a therapeutic effect. In particular, the subject may have diabetes.
The wound to be healed may include any injury, trauma or injury to any part of the body of the subject. Examples of wounds that can be treated by this method include acute conditions or wounds; such as thermal (hot or cold), chemical, radiation, electrical, and burns caused by excessive exposure to ultraviolet radiation (e.g., sunburn); damage to body tissues, such as the perineum resulting from labor and childbirth; wounds inflicted during medical procedures, such as vulvotomy, traumatic injuries, including incisions, surgical incisions, abrasions; accidental injury; post-operative injuries and chronic conditions; such as pressure sores, ulcers, conditions associated with diabetes and poor circulation, and all types of acne. In addition, wounds may include dermatitis, wounds after dental surgery; periodontal disease; post-traumatic wounds; and tumor-associated wounds. Other examples are gastrointestinal tract trauma, such as occurs during gastritis or inflammatory bowel disease.
Thus, the term "wound" is used broadly herein to include any breach of the integrity of or any injury or damage to a tissue. Thus, the term includes any injury, trauma or injury to tissue or any injury, regardless (e.g., due to accidental or traumatic injury, surgery or other expected or purposeful injury or disease). The trauma may include any physical or mechanical injury or any injury caused by external agents including pathogens or biological or chemical agents. Tissue damage may also be caused by hypoxia, ischemia, or reperfusion. The wound may comprise any type of burn. The wound may be acute or chronic. A chronic wound may be described as any wound that is not arrested in the healing phase, for example, any wound that is not healing during the inflammatory phase, or for 30, 40, 50 or 60 days or more. Wounds may be present in the internal or external surfaces or tissues of the body.
In particular embodiments, the wound is on an external surface or tissue of the body, such as a skin (i.e., skin) wound or mucosal wound, particularly a wound on an external mucosal tissue or surface of the body (e.g., on the eye, ear, or nose, etc.). In another embodiment, it is a gastrointestinal tract wound. In various embodiments, it is not a gastrointestinal wound (i.e., it is a wound other than a gastrointestinal wound).
The bacteria may be administered in any convenient or desirable manner, for example orally or topically, or by direct administration to the wound site, for example by direct injection or infusion or application or introduction of a pharmaceutical composition or dressing or device containing the bacteria. In other embodiments, it may be administered orally, or intranasally or by inhalation, rectally or vaginally. Thus, bacteria may be administered to, or through, any aperture of the body. For administration to a gastrointestinal wound, the bacteria may be administered orally.
The bacteria may be formulated or prepared for administration by any of the above routes in any convenient or desirable manner, according to the protocol and using means and routes well known in the art. Thus, in addition to pharmaceutical compositions, medical devices, dressings and the like, the probiotic products of the present invention may be formulated and provided in or on a nutritional supplement or food, such as a functional food.
Administration forms for oral administration include powders, tablets, capsules, solutions and the like. For topical application, the product may be formulated as a liquid such as a suspension or spray or aerosol (powder or liquid), gel, cream, lotion, paste, ointment or salve, and the like, or as a dressing of any form, such as a bandage, plaster, pad, strip, swab, sponge, pad, and the like, with or without a solid support or substrate. In addition, bacteria can be disposed (e.g., coated) on the surface of a medical device, such as an implant (e.g., a prosthetic implant), a tube, a wire, or a catheter.
The bacteria may be provided in any convenient or desirable form, for example, as an active or growing culture or in lyophilized or freeze-dried form.
The bacterial strains according to the invention may be formulated for topical or oral administration to treat surface wounds of the skin or mucosa. Accordingly, the present invention further provides a probiotic product comprising a bacterial strain according to the present invention. The probiotic product is for example a pharmaceutical composition, preferably for oral administration. Alternatively, for topical application, the probiotic product is, for example, a lotion or a lotion soaked wound dressing comprising a bacterial strain according to the invention.
The products of the invention (i.e. pharmaceutical compositions or devices or dressings, etc.) may also contain an inducing agent (in which an inducible promoter is used). This may be provided as part of the product (e.g. incorporated into or included in the dressing) or separately, e.g. as part of a kit or combination product, as defined above.
When co-formulated in a product (e.g., a dressing or device), the bacteria and inducer can be provided in a form in which the bacteria are separated from the inducer and brought together (or brought into contact) at the time of use. For example, the bacteria and inducer may be in separate compartments and brought together (e.g., contacted or mixed) at the time of use, or may be separated by a barrier (e.g., a membrane or other partition) that may be broken or collapsed or opened at the time of use.
Alternatively, the inducer can be formulated and provided separately (e.g., in a kit that also contains the bacteria, or a product that contains the bacteria), and the inducer and the bacteria (or product that contains the bacteria) can be brought together (e.g., contacted) during use. This may be done before, during or after administration to the subject. For example, a product comprising bacteria may be administered first, and then an inducer may be added or applied to the bacteria. In another embodiment, the bacteria and the inducing agent can be pre-mixed prior to (e.g., immediately prior to or immediately prior to) or during administration.
When the bacteria are provided in lyophilized or freeze-dried form, it may be desirable to reconstitute or resuspend the bacteria prior to administration (e.g., prior to or during use). This may depend on the wound and the format of the product used. For example, in the presence of some wounds, sufficient fluid may be present to allow the bacteria to be reconstituted/resuspended and become active. However, in other embodiments, it may be desirable to provide a liquid for reconstituting (or alternatively expressed as, for suspending or resuspending) the bacteria. This may be provided in a separate vessel (vessel) or container (container), e.g. as part of a kit or combination product, or in a separate compartment of a container or vessel or device. The liquid may contain or contain the inducer, or when the inducer is present, the inducer may be provided in a separate vessel or container or compartment. The liquid may be any suitable liquid for reconstituting or suspending the freeze-dried bacteria, e.g. water or an aqueous solution, or a buffer or a growth medium or a culture medium.
Thus, as an example, a two-compartment system (e.g., in a dressing or device or container or vessel (e.g., a bottle)) may include freeze-dried bacteria in one compartment and a liquid in the other compartment. The liquid may optionally contain an inducer. In use or prior to use, the two compartments may be mixed or brought into contact and applied to the wound. In more specific embodiments, the bacteria may be applied to the wound in liquid form, and then a separate dressing may be applied. Thus, in a simple embodiment it can be seen that the kit may simply comprise a first vessel or container containing the freeze-dried bacteria and a second vessel or container containing the liquid used to reconstitute the bacteria. Optionally, the kit may also contain an inducing agent, which is also contained in the second vessel or in a separate third vessel or container.
Thus, for example, the probiotic product preferably comprises an activating peptide capable of activating the expression of the protein that is desired to be expressed in the lactic acid bacteria strain. The activating peptide is preferably the peptide SppIP (i.e., a peptide comprising the amino acid sequence of SEQ ID NO: 19 or a sequence having at least 80% sequence identity thereto).
For skin wounds, the wound dressing may comprise freeze-dried bacteria in one compartment and an activating peptide in another compartment. When applied to a wound, the two compartments are brought together to bring the bacteria into contact with the activating peptide. Alternatively, bacteria may be contained in the gel-like structure on the adhesive side of the water resistant plaster or on the side of the dressing in contact with the exudate. In use, the activated peptide is applied manually to the bacteria and the plaster or dressing is applied to the wound site.
The live bacteria may also be contained in hydrocolloids, such as natural gelatin. The bacteria can be incorporated into hydrocolloid films, such as gelatin films, by cross-linking, plasticizing and drying them, and keeping the bacteria active during storage until hydration. Live bacteria may also be encapsulated in the crosslinked electrospun hydrogel fibers. In this form, freeze drying of the bacteria is not required.
For wounds in the gastrointestinal tract, a tablet is designed comprising at least two separate compartments, wherein one compartment comprises freeze-dried bacteria and the other compartment comprises a liquid and an activating peptide. The tablets are compressed prior to ingestion to break the inner membrane separating the two compartments and mix the contents together. For wounds in the oral cavity (e.g. on the gums), the bacteria according to the invention can be applied as a highly viscous paste.
In particular, formulations for topical application to the skin may include ointments, creams, gels, and pastes, applied in a pharmaceutically acceptable carrier. Topical formulations may be prepared using oily or water-soluble ointment bases as are well known to those skilled in the art. For example, these formulations may include vegetable oils, animal fats, and more preferably semi-solid hydrocarbons obtained from petroleum. The specific ingredients employed may include white ointment, yellow ointment, acetyl ester wax, oleic acid, olive oil, paraffin, vaseline, white vaseline, spermaceti, starch glyceride, white wax, yellow wax, lanolin, anhydrous lanolin and glyceryl monostearate. Various water-soluble ointment bases may also be used, including, for example, glycol ethers and derivatives, polyethylene glycol, polyoxyethylene 40 stearate, and polysorbate.
The bacterial strains may be in and/or on a substrate, solid support and/or wound dressing to provide delivery of the active substance to the wound. The solid support or matrix may be a medical device or a part thereof. As used herein, the terms "matrix" or "solid support" and "wound dressing" refer broadly to any matrix that is prepared for a wound and applied to the wound for the purpose of protecting, absorbing, draining the wound, and the like.
In one embodiment, the invention provides a wound healing material or dressing attached to or comprising a transformed bacterial strain, i.e. the dressing is a carrier for application of the transformed bacteria of the invention. Alternatively, the carrier may be a plaster or bandage. The present invention may include any of a number of types of substrates and/or backings that are commercially available, and the choice of wound healing material will depend on the nature of the wound to be treated. The most commonly used wound dressings are briefly described below.
Transparent film dressings are made of, for example, polyurethane, polyamide or gelatin. These synthetic membranes are permeable to water vapour oxygen and other gases, but impermeable to water and bacteria, have low water absorption, are suitable for low exuding wounds, gels (hydrocolloid particles in combination with polyurethane foam), hydrocolloids (cross-linked polymers containing approximately at least 60% water, have a high absorption capacity and remove toxic components from the wound bed and maintain the moisture level and temperature at the wound site), foams (hydrophilic or hydrophobic, e.g. polymeric foam dressings made by modifying polyurethane foam, have good absorption and are permeable to water vapour), calcium alginate (non-woven fibrous composites of calcium alginate from alginate gel groups, alginate having a very high absorption capacity. They also promote autolytic debridement, as ion exchange between alginate and exudate converts insoluble calcium alginate into soluble sodium alginate, providing a moist, intact surface for the wound bed ideal for wound healing) and cellophane (cellulose and plasticizer). The shape and size of the wound may be determined from the measurements provided for the wound and the wound dressing may be customized to the exact site. Since wound sites may differ in mechanical strength, thickness, sensitivity, etc., the matrix may be molded to specifically address the mechanical and/or other needs of the site. For example, for highly innervated locations, such as fingertips, the thickness of the substrate may be minimized. Other wound sites, such as fingers, ankles, knees, elbows, etc., may be exposed to higher mechanical stresses and require multiple layers of substrates.
In another aspect, the invention provides a method for healing a wound in a human or animal subject, comprising administering to a human or animal subject in need thereof a bacterial strain according to the invention. The bacterial strain is preferably comprised in a pharmaceutical composition or wound dressing as described above. In such methods, the human or animal subject is preferably in need of wound healing due to an underlying medical condition that results in impaired wound healing, such as reduced peripheral blood perfusion (peripheral arterial disease), hyperglycemia, or neuropathy.
The results obtained and contained in the following examples demonstrate the advantages of the present invention. In particular, improved wound healing (e.g., in terms of better or faster wound closure) may be obtained by using the transformed protein-expressing bacteria of the invention compared to, for example, direct protein preparations (i.e., protein only, no bacteria) or bacteria alone (bacteria that have not been modified to express proteins, e.g., no recombinant plasmids). Furthermore, an improved effect when applying bacteria to wounds can be seen compared to applying a supernatant obtained from a transformed bacterial culture. Therefore, it is advantageous to deliver proteins to wounds by a host of lactic acid bacteria that express the proteins. It is believed that synergistic effects may be possible. In other words, there may be a synergistic effect between the effect of the bacteria on wound healing and the effect of the protein on wound healing. Thus, in some embodiments, there may be a greater cumulative effect on wound healing than transformed bacteria, relative to the effect of the corresponding untransformed bacteria (i.e. without plasmid) and the effect of the protein when provided as a protein (i.e. not expressed from the in situ bacteria).
In this regard, it is believed that the pH lowering effect of the bacteria, for example, at the wound site, may help to increase or enhance or promote the activity of the protein. While not wishing to be bound by theory, it is also believed that administration of the transformed bacteria according to the invention may have a beneficial effect in enhancing macrophage activity at the wound site. For example, the number of macrophages may be increased.
The effect of the transformed bacteria on wound healing may or may not be immediate, and may take some time to see (before improved wound healing can be observed, e.g., 1, 2, 3, 4, 5, or 6 or more hours or longer, e.g., 8, 10, 12, 15, 18, 20, or 24 hours or longer, or 1, 2, 3, 4, 5, or 6 or more days, e.g., 8, 10, 12, 15, 18, 20, or 24 or more days). For chronic wounds in elderly people it may take longer to see the difference between the treated and control groups, for example it may take about 12 weeks.
A particular and important use of the invention is in the treatment of chronic wounds, in particular ulcers, and in particular in the treatment of diabetic foot ulcers.
The prevalence rate of chronic foot ulcers in diabetic patients is about 18%. In 2013, the European population reaches 74250 ten thousand, and the number of patients with diabetes patients reaches 3270 ten thousand, wherein 290-580 ten thousand patients have chronic foot ulcers. The average duration of this type of ulcer is in the range of several months, with less than 25% of wounds healing in 12 weeks when given standard of care. The final stage in this case is amputation of the affected limb. The current treatment of persons with chronic foot ulcers is divided into primary care, home care, nursing home, relatives, self-management and visits to a hospital wound clinic. Current treatments rely on the use of surgical debridement to unload, remove dead and dead tissue, repeated wound dressing changes, systemic antibiotics, and in special cases, treatment with live larvae or collagenase, and hyperbaric oxygen therapy in several places in sweden. If the underlying cause also includes a large arterial blockage, it can be surgically corrected by bypass vein grafting. Wounds are now treated every two to three days. Treatment with the proposed modified lactic acid bacteria in any of the proposed forms or formulations does not disrupt this conventional approach. Thus, improving the healing of these wounds by the treatment of the present invention would therefore have considerable economic benefit as well as personal benefit to the patient.
The bacteria are active and produce the encoded protein in vivo and deliver it to the wound surface for a period of time (e.g., about 1 hour). They may become inactive and die. Slow or dead lactic acid bacteria can be left without risk in the wound/dressing environment until the dressing is normally replaced.
The biotherapeutic agent according to the invention will have a significantly lower production cost compared to protein drug compounds. This is because the biotherapeutic agent produces the active protein itself directly in the wound.
Open wounds such as diabetic foot ulcers and loss of foot function cause considerable discomfort and even disability to the patient and may have a significant negative impact on the quality of life, including significant risk or infection and therefore long term use of antibiotics, and eventual amputation. Thus, improved wound healing would be of great personal benefit to the patient, and also of benefit in reducing antibiotic use (and hence the spread of antibiotic resistance). It is believed that treating such chronic wounds according to the present invention can increase the endogenous alarm signal in the wound and initiate the healing process in a poorly arrested or chronic wound and accelerate the healing time.
In addition, the present invention may have the advantage of flexibility and ease of use for medical personnel.

The sequence of murine CXCL12-1 alpha was optimized for translation in Lactobacillus reuteri using DNA 2.0(Menlo Park, CA, USA) by Stefan Roos, university of agricultural Sciences (SLU). The optimized sequence (SEQ ID NO: 1) was synthesized from DNA 2.0 in plasmid vector pJ 204. Sequences of human CXCL12-1 α, murine CXCL17, human CXCL17, murine Ym1 and human Ym1 were optimized for translation in lactobacillus reuteri using GenScript (Piscataway, NJ, USA) by Stefan Roos, university of sweden agricultural Science (SLU). The optimized sequence is shown as SEQ ID NO: 4 (human CXCL12-1 α); SEQ ID NO: 7 (murine CXCL 17); SEQ ID NO: 10 (human CXCL 17); SEQ ID NO: 13 (murine Ym 1); and SEQ ID NO: 16 (human Ym 1).
Primers were designed to detect the insert (hCXCL12opt) in pllab 112, 171 bp:
5’GCAGCCTTAACAGTCGGCACCT3’(SEQ ID NO:22);
5’ACGTGCAACAATCTGCAAAGCAC3’(SEQ ID NO:23)。
the ends of the insert were also optimized for continued molecular processing to make the insert fit into the new vector pllab 112. The optimized mCXCL12opt sequence was delivered in plasmid PJ 204. Coli PK401 was transformed with pJ 204. The plasmids (pLAB112 and pJ204) were cut with the restriction enzymes XhoI and NcoI in NEB2 buffer. The fragment mCXCL12opt was then purified on gel. The mCXCL12opt insert was then ligated into the pllab 112 vector using T4 DNA ligase to give the construct mLrCK1. The insert construct in the pllab 112 vector was verified by PCR. The construct was then verified by sequence analysis (Macrogen). Finally, lactobacillus reuteri strains R2LC and DSM20016 were transformed with mLrCK1, two R2LC clones (4 and 7) positive for the construct were collected and the plasmids mLrCK1 (now mLrCK1.4 and mLrCK1.7) from these colonies were again verified by sequence analysis (Macrogen).
Plasmids hLrCK1, mLrCK2, hLrCK2, mlrcp 1 and hlrcp 2 (see table II below) were produced in a similar manner following the same protocol and procedure.

In vitro analysis of plasmid expression
L.reuteri R2LC pLAB112_ Luc was cultured overnight, plated again on 96-well plates (200. mu.l/well) when cultured to OD 0.5 or immediately resuspended directly from the freeze-dried preparation. The luminescence intensity was determined by non-invasive bioimaging (IVIS Spectrum, Perkin Elmer). A baseline image at time 0 is acquired. The activated peptide SppIP (50ng/ml) and D-fluorescein (150. mu.g/ml) were then added immediately. The plate was imaged at 5 minutes and then every 30 minutes for 1400 minutes. Data were quantified using the Living Image 3.1 software (Perkin Elmer) and imaging parameters were retained for comparative analysis. The luminescence intensity is considered to be proportional to plasmid expression.
Animal(s) production
The experiments were approved by the ethical committee on laboratory animals in the area of uppsala. CX3CR1 with mouse C57B1/6(Taconic) and C57B1/6 background+/GFP(originally from Jackson laboratories). The animals had free access to moisture and food during the experiment.
Wound induction
Mice were anesthetized (1-3% isoflurane, 200ml/min), shaved and then depilatedApplication was performed for 1 minute (washed with water) to remove hair from the hind limb. Whole-layer (epidermal, dermal and subcutaneous) wounds were induced using a sterile needle biopsy needle (5mm diameter). Topical analgesics (Embla cream) were applied daily for the first 5 days.
Topical wound treatment
Wounds were treated daily with 25 μ l saline, lactobacillus reuteri R2LC pllab 112_ Luc or R2LC pllab 112_ LrCK1. The bacteria were cultured overnight, re-inoculated and cultured to OD 0.5, pre-activated for 5 minutes before administration of the activating peptide SppIP (50ng/ml) and added locally to the middle of the wound surface. For the dose experiments, the wounds were treated daily with lactobacillus reuteri R2LC plb 112_ LrCK1 in the middle, inoculated and grown again with 25 μ Ι saline or from overnight culture to OD 0.5, pre-activated for 5 minutes before administration of the activating peptide SppIP (50ng/ml), and added locally to the wound surface at a concentration of OD 0.2, 0.5, 1.0 or 1.25. For comparative experiments with various proteins, wounds were treated daily with 10 μ l saline or murine CXCL12, CXCL17 or Ym1 (total 200ng protein in 60 μ l saline given 1 hour at 10 minute intervals). For dose escalation studies of CXCL12, 200ng, 600ng, or 1 μ g of CXCL12 in 10 μ l saline was added to the wound once daily at the same time point.
In vivo analysis of plasmid expression
L.reuteri R2LC pLAB112_ Luc was cultured overnight, re-inoculated and cultured to OD 0.5. The luminescence intensity was determined by non-invasive bioimaging (IVIS Spectrum, Perkin Elmer). A baseline image at time 0 is acquired. Then 25. mu.l of Lactobacillus reuteri R2LC pLAB112_ Luc was added in the middle of the wound. The bacteria were pre-activated for 5 minutes before administration of the activating peptides SppIP (50ng/ml) and D-fluorescein (150. mu.g/ml). Mice were imaged every 15 minutes for 270 minutes. Data were quantified using the Living Image 3.1 software (Perkin Elmer) and imaging parameters were retained for comparative analysis. The luminescence intensity is considered to be proportional to plasmid expression.
Wound size and appearance monitoring
Anesthetized mice (1-3% isoflurane, 200ml/min) were monitored daily for wound size and appearance by taking conventional photographs. A scale bar was included in the captured Image and the wound size was analyzed using Image J (NIH's free software). When size is changed<0.5mm2At the time, the wound is considered to be healed.
Skin blood flow monitoring
Blood flow in the whole hind limb with a healing wound was measured in anesthetized (1-3% isoflurane, 200ml/min) mice using non-invasive laser speckle contrast analysis and the data PIMSoft 3(Perimed) was analyzed. The limb (reading frame 1.4 x 1.4cm) was imaged at 10 images/second over two minutes, averaging 20 times. Data are expressed in perfusion units (PFU).
Reduced perfusion
Mice were anesthetized (1-3% isoflurane, 200ml/min) and hind limb ischemia was induced by ligation and excision of the femoral artery above the superficial abdominal artery branch.
Induction of hyperglycemia
A single dose of alloxan monohydrate (8mg/ml, 1. mu.l/g body weight), i.e. dissolved in sterile saline, was injected into the tail vein. Blood glucose and body weight were monitored daily throughout the experiment. Hyperglycemia is defined as blood glucose >16.7 mmol/l.
Statistical analysis
Data are presented as mean ± SEM. Post hoc tests of all columns were compared with Bonferroni using two-way anova to analyze the change in healing process over time. Post hoc tests of all columns were compared with Bonferroni using one-way anova to analyze the healing process at one time point for the group with n >2, and student unpaired two-tailed t-test was used to analyze the healing process at one time point when n-2. p <0.05 is considered statistically significant.
Example 1: growth of bacteria transformed with plasmid LrCK1
Lactococcus lactis containing mlrCK1 was cultured overnight, inoculated again and grown to OD 0.3 or 0.5, showing NO growth failure when 10 or 50ng/ml of the activating peptide SppIP (SEQ ID NO: 19) was added. During these growth experiments, the pH was measured and decreased the most during the growth phase and then stabilized around pH6.7 when grown as an intermediate medium (Mes-medium) (fig. 1). (skin pH 5.5, wound pH 7.15-8.9, where alkaline pH is associated with lower healing rates (ref. 14))
Example 2: expression of plasmid pLAB112_ Luc
In vitro expression of plasmid plb 112_ Luc in lactobacillus reuteri R2LC re-inoculated and grown for 2 hours from overnight culture was maintained for up to more than 600 minutes (10 hours). The plasmid not activated by the activation peptide SppIP did not leak/express (fig. 2).
When lactobacillus reuteri R2LC (with plb 112_ Luc) was placed in a 1-day-old full-thickness wound in anesthetized mice, re-inoculated from an overnight culture and grown for 2 hours, the bacteria were restricted to the wound site only, and plasmid expression was high at the first hour, but signals were detected over 4 hours (fig. 3).
Example 3: improved wound healing in healthy mice
The wound was monitored daily during the healing process. Healthy mice with a single daily application of lactobacillus reuteri R2LC _ pllab 112_ mlrck1.4 had reduced time to 75% closure and 100% closure to the wound surface compared to control mice with no wound applied anything and mice with daily application of the control lactobacillus reuteri R2LC (pLAB112_ Luc) (fig. 4). The first few days after wound induction, the effect of lactobacillus reuteri R2LC _ pllab 112_ mlrck1.4 on wound healing was most pronounced. The size of the wound was further reduced by daily administration (one and two days after wound induction) of lactobacillus reuteri R2LC _ pllab 112_ mlrck1.4 when compared to control mice without any substance administered to the wound. The total wound exposure, measured as the area under the curve, was also reduced in this group compared to control mice with no wound applied with any substance (fig. 5). Figure 35 shows representative images of whole skin wounds induced in healthy mice at time 0 and 24 hours post treatment with R2LC Luc or R2LC LrCK1 without treatment.
Example 4: improved wound healing in healthy mice with impaired tissue perfusion
By ligating the femoral artery of the limb where the wound was located, there was a 50% reduction in skin perfusion on the day of wound induction (figure 6 and table III). In ischemic mice, a single daily administration of lactobacillus reuteri R2LC _ pllab 112_ mlrck1.4 resulted in a reduction in time to 50% and 75% closure of the wound surface compared to control mice with no substance applied to the wound and mice with daily administration of the control lactobacillus reuteri R2LC (pllab 112_ Luc) (fig. 7). In addition, in mice with reduced skin perfusion, the effect of lactobacillus reuteri R2LC _ pllab 112_ mlrck1.4 on wound healing was most pronounced the first few days after wound induction. The size of the wound was reduced by daily administration of lactobacillus reuteri R2LC _ pllab 112_ mlrck1.4 one and two days after wound induction compared to control mice without any substance applied to the wound. The total wound exposure was also reduced in this group compared to control mice with no wound applied with any substance (fig. 8).

Example 5: improved wound healing in hyperglycemic mice
Mice were made diabetic with alloxan, after which they remained hyperglycemic (>16.7mmol/l) during wound healing and did not lose weight (fig. 9). The time to 75% wound surface closure was reduced in diabetic mice with a single daily application of lactobacillus reuteri R2LC _ pllab 112_ mlrck1.4 compared to control mice with no wound application of anything and mice with a single daily application of the control lactobacillus reuteri R2LC (pllab 112_ Luc) (fig. 10). There was a tendency to reduce wound exposure (p 0.08) in diabetic mice administered lactobacillus reuteri R2LC _ plb 112_ mlrck1.4 daily compared to control mice administered lactobacillus reuteri R2LC containing Luc daily and without wound application of anything (fig. 11).
Example 6: CXCL12 skin overexpression in the dermis of the wound margin transfected with a plasmid encoding CXCL12
Plasmids were constructed on the pVAX1 backbone with the CMV promoter (SEQ ID NO: 24) (V260-20, Invitrogen, Waltham, MA, USA) and the insert-copGFP-T2A-Luc 2-referred to as pCTR (SEQ ID NO: 25) -or-CXCL 12-P2A-copGFP-T2A-Luc 2-referred to as pCXCL12(SEQ ID NO: 26) -was introduced as previously described (reference 18). The secretory sequence of CXCL12 was replaced with the murine IgG secretory sequence. Thus, the pCTR plasmid encodes GFP (green fluorescent protein) and luciferase, but no chemokines. The plasmid (40. mu.g in 100. mu.l total volume of saline) was injected into the dermis at four sites of the wound margin. Transgene expression was measured over time based on luciferase activity after intraperitoneal injection of D-luciferin (150mg/kg, #122796, Perkin Elmer, Waltham, MA, USA) 10 minutes before anesthesia, and image acquisition was performed using a bioimaging apparatus (IVIS Spectrum, Perkin Elmer). Data were quantified using the Living Image 3.1 software (Perkin Elmer) and imaging parameters were retained for comparative analysis. The setup of selecting the region of interest minus the contralateral reference region is also retained. The luminescence intensity is considered to be proportional to plasmid expression.
Plasmid expression from the dermis at the wound margins was measured using non-invasive bioimaging and correlated with light produced by luciferase encoded by a plasmid comparable to CXCL12 expression. Expression peaked on day 2 and then declined as the wound was closed and the dermis reconstituted (figure 13). Overexpression of CXCL12 did not result in accelerated complete wound healing compared to pCTR, but rather in a reduced time to 75% closure of the wound surface (fig. 14). Wound surface was reduced by pCXCL12 dermal expression compared to pCTR 4-6 days after wound induction and dermal transfection (figure 15). These results indicate that CXCL12 delivered to the wound using this system had no apparent effect for the first 24 hours and was less effective at later time points.
Example 7: dose effect of Lactobacillus reuteri with topical treatment with Luc and LrCK1
Lactobacillus was again inoculated from overnight cultures and grown to OD 0.5, then diluted or concentrated in MRS to OD 0.2, 0.5, 1.0 and 1.25. Diluting four different concentrations by 10 times to 10 times-9Mu.l of each sample was plated on MRS agar containing erythromycin and incubated overnight at 37 ℃ in an anaerobic chamber with 5% carbon dioxide overnight. Colonies on the plate were counted and the concentration expressed as colony forming units per ml (CFU/ml).
For the dose experiments, the wounds were treated daily for two days with 25 μ l of saline or lactobacillus reuteri R2LC plb 112_ lcck 1.4, which lactobacillus reuteri R2LC plb 112_ lcck 1.4 was re-inoculated and cultured to OD 0.5 from an overnight culture, pre-activated for 5 minutes before administration of the activation peptide SppIP (50ng/ml) and then added locally in the middle of the wound surface at a concentration of OD 0.2, 0.5, 1.0 or 1.25. 5X 10 out of 25. mu.l OD 0.57Bacteria (2X 10)9cfu/ml), meaning a 1000-fold dose span.
The bacterial concentration was measured by optical density and the colony forming units per ml are shown in figure 16. Minimum dose cultured and activated before application to the wound (OD 0.2 equals 2X 10)7Bacteria) resulted in the smallest wound size after 24 hours, all four different concentrations resulted in significantly accelerated wound closure at 24 and 48 hours post wound induction (fig. 17A), thus resulting in a reduction in the first 48 hours of wound exposure compared to wounds that received no treatment (fig. 17B). These results indicate that the initial 48 hour dose administered was the lowest dose of 10 compared to untreated wounds3Multiple (OD 1.25 equals 1X 10)10Bacteria) that produces the greatest effect and also significantly accelerates wound healing to the same extent as the dose that produces the greatest wound closure. No signs of causing inflammation or other negative side effects were observed for the wounds given the highest dose. The data show that even low doses of lactobacillus reuteri R2LC _ LrCK1 can accelerate wound healing.

To study the effect of the dose of mCXCL121 a applied to the wound surface, 0.2 μ g, 0.6 μ g, or 1 μ g of mCXCL121 a (Rnd Systems) was dissolved in 10 μ l saline and delivered to the wound daily for two days. Administration is once daily.
Delivering mCXCL121 a once daily at a separate time point did not accelerate wound healing on the first two days compared to no treatment (fig. 18A, B). These data indicate that continuous delivery of CXCL121 a results in accelerated wound healing, as administration of a total of 0.2 μ g of mCXCL121 a at 10 minute intervals over one hour per day accelerates healing during the first 48 hours (fig. 18 and 19).
Example 9: re-epithelialization assay in human skin biopsies
Healthy white women who underwent conventional breast reduction at the university Hospital of Uppsala agreed to donation to obtain sterile normal human skin. The samples were overlaid with physiological DMEM supplemented with 2% calf serum (Hyclone, Hyclone Laboratories, Logan USA) and shipped to the laboratory under sterile conditions.
Subcutaneous tissue was removed and the remaining dermis and epidermis were cut using a 6mm skin biopsy punch (Integra Miltex, York, PA, USA) and sterile scissors as previously described (reference 17). At the center of each 6mm diameter circular skin, the epidermis was removed using a 3mm skin biopsy punch and sterile scissors. The samples were then individually placed in sterile 24-well plates with the epidermis facing upward. All media (DMEM) were supplemented with BSA, 2 or 10% and antibiotics (erythromycin Sigma Aldrich, Buchs, Swizerland, 10. mu.g/ml). To maintain the dermal side nutrients, i.e. the highest concentration of nutrients on the dermal side of the skin, 0.5ml of medium was added to each well and the medium was changed daily. 10 of 10. mu.l MRS were added while changing the medium6A single lactobacillus reuteri R2LC _ Luc or lactobacillus reuteri R2LC _ LrCK1 was placed in the middle of the epidermal wound in floating round skin. Inoculating bacteria and growing in MRS for 2-4 hr to makeIt is in the exponential phase. The samples were incubated at 37 ℃, 5% carbon dioxide and 95% humidity for 14 days.
The sample was cut in the middle, half was fixed in 4%, ph7.38 formaldehyde overnight and dehydrated through the ethanol-xylene series, and finally embedded in paraffin. A cross section (10 μm) from the central part of the sample was mounted, deparaffinized, rehydrated and stained with hematoxylin and eosin. Images were taken using a Leica Leits Dmrb with a Leica DFC 420C camera and a Plan Fluot 40 x 0.7NA objective lens. The re-epithelialization or epidermal sleeve length was measured in the images using Image J (NIH).
Lactobacillus was added to the round skin in culture, decreasing the pH of the medium when measured after 24 hours (fig. 20A). The epidermis of the wound edges induced in the round skin proliferated to cover the exposed dermis when 10% FCS was present in the culture medium, and there was almost no proliferation of the round skin in the culture after 14 days when cultured in the culture medium containing 2% FCS (fig. 20B). No macroscopic detrimental effects were detected in round skin treated with R2LC pllab 112 Luc or R2LC pllab 112_ LrCK1, and increased re-epithelialization was measured on wounds in round skin discs treated with R2LC pllab 112_ LrCK1 for 14 days (fig. 20B).
Example 10: function of bacteria after freeze drying and recovery
Different protocols and 35 different freeze-drying formulations were tested and viability was determined up to two months. In addition, a large batch of freeze-dried lactobacillus reuteri was also produced in the same set-up as for large-scale industrial production and according to good manufacturing practices. The activity of the freeze-dried samples of this batch was analyzed after storage for up to two months at a temperature range of-20 to 40 ℃. The freeze-dried bacteria were revived by adding equal volumes of water or MRS medium containing SppIP (50ng/ml) and then immediately analyzed for expression in vivo and in vitro by plating them in 96-well plates or applying them directly onto 1 day old wounds as described above.
With the most promising formulations, the activity ranges from immediately after freeze-drying to two months on storageThe measurement was stable at +4 ℃ for the sample. The activity is within the acceptable range for freeze-dried bacteria currently marketed as dietary supplements. Direct measurement of plasmid expression after resuscitation of freeze-dried lactobacillus reuteri R2LC _ plb 112_ Luc showed immediate induction of expression, which peaked and then declined after 450 minutes (fig. 21). After 24 hours (1440 minutes) there was no expression, no viable bacteria. When the freeze-dried Lactobacillus reuteri R2LC _ pLAB112_ Luc was resuscitated, it was induced with 50ng/ml (SppIP) and immediately placed on the skin wound of mice (5X 10)725 μ l), expression increased directly and was high in about 1 hour (fig. 22), in a similar pattern seen when fresh growth stage bacteria were added to the solution (fig. 3).
Testing the Effect on wound healing, wherein bacteria were freeze-dried (5X 10)7/25 μ l) were resuscitated, induced and immediately placed on the skin wound of the mice. The wounds were monitored daily for two days and the wounds treated with lactobacillus reuteri R2LC _ pllab 112_ LrCK1 showed accelerated healing compared to the wounds treated with lactobacillus reuteri R2LC _ pllab 112_ Luc (fig. 23) using this protocol. These data show that lactobacillus reuteri R2LC _ plb 112 need not be pre-cultured to an exponential growth phase in order to produce and deliver sufficient CXCL12 to accelerate wound healing in vivo.
Example 11: pH-dependent effects of chemokine signaling
Chemokines can occur as monomers, dimers or multimers that interact with themselves or other chemokines (see reference 22). Different combinations and conformations induce different receptor signaling and therefore different cellular responses (ref. 34). This is a new and unexplored area, the combination of possibilities depending on the local tissue microenvironment. Local pH also affects local macrophage function (reference 23).
To study the pH-dependent effect of chemokine potency, 0.2 μ g CXCL121 α in 10 μ l saline at pH 7.35, 6.35 or 5.35 was applied daily to the wound for two days.
Changing the pH in the chemokine-containing buffer had an effect on the healing pattern of the treated wound, and there was a tendency for smaller wound size (p ═ 0.07) one day after wound induction when CXCL12 was suspended in saline at pH 6.35 compared to CXCL12 suspended in saline at pH 7.35 (fig. 24). These data indicate that a pH of 6.35 enhances the effect of recombinant CXCL12 applied to the wound surface in inducing accelerated wound healing.
Example 12: importance of the effectiveness of bacteria at the wound surface site for chemokine delivery
For wound treatment with fresh supernatant, lactobacillus reuteri R2LC _ plb 112_ Luc and R2LC _ plb 112_ LrCK1 were inoculated into 10ml MRS at 37 ℃, grown to OD 0.5, centrifuged (>2000rpm, 5 min), resuspended in 1ml MRS, activated (SppIP, 50ng/ml) and grown for 4 hours. The samples were then centrifuged (>2000rpm, 5 minutes) and the supernatant retained. Then 25 μ l of this supernatant was applied to the wound once daily for two days.
The importance of CXCL121 a delivery directly to wound surface bacteria by lactobacillus reuteri R2LC _ plb 112_ LrCK1 was demonstrated in a model where fresh supernatant from induced lactobacillus reuteri was added to the wound daily for two days after wound induction. There was no difference in wound size or total wound exposure (p 0.2595) treated with fresh supernatant from lactobacillus reuteri R2LC _ plb 112_ Luc or R2LC _ plb 112_ LrCK1 (fig. 25).
Example 13: lactobacillus delivered CXCL12 increases CXCL12 in periwound skin Is on the horizon of
For quantitative analysis, the skin surrounding the wound (0-100 μm from the wound) was removed on the last day of the experiment and flash frozen in liquid nitrogen and sectioned (10 μm). After fixation in ice-cold methanol (10 min) and permeabilization in 0.5% Triton-X (15 min), tissues were incubated with antibodies targeting CXCL121 α (polyclonal antibody, Abcam), washed with the macrophage cell antigen F4/80 (clone BM8, eBioscience), and incubated with matching secondary antibodies coupled to Alexa Fluor488 and Nordic Lights 557 (Invitrogen). The tissue was finally washed and mounted (fluorocount, #0100-10, Southern Biotech, Birmingham, AL, USA) before using an in-line scanning confocal microscope (Zeiss LSM 5Live, piezo-electric motor controlled WPlanApo 40 ×/1.0 with 0.5 optical zoom, Zeiss, Oberkochen, Germany). Protein levels and macrophages were quantified in the images using Image J (NIH) and IMARIS software 8.2(Bitplane, Zurich, Switzerland). The microscope settings were maintained during acquisition for comparison. CXCL121 α measurements are expressed as Mean Fluorescence Intensity (MFI).
Treatment of the wounds with different doses of lactobacillus reuteri R2LC _ plb 112_ LrCK1 once daily for two days resulted in increased skin tissue levels of CXCL121 α in the skin beside the wounds compared to the skin beside the wounds that did not receive treatment (fig. 26). This is the same in both the dermis and epidermis and in the hair follicle.
Example 14: delivered lactobacillus CXCL12 increased macrophages in the skin surrounding the wound
When applying lactobacillus reuteri R2LC _ plb 112_ LrCK1 at OD 0.2 and OD 0.5 to the wound, the wound was treated once daily with different doses of lactobacillus reuteri R2TC _ plb 112_ LrCK1 for two days compared to the dermis next to the wound not receiving treatment, resulting in F4/80 in the dermis near the wound two days after wound induction+The density of macrophages increased (fig. 27A). When OD1.25 of Lactobacillus reuteri R2LC _ pLAB112_ LrCK1 was applied to the wound surface, F4/80 in the epidermis beside the wound 2 days after wound induction compared to the epidermis beside the wound not receiving the treatment+Macrophages increased (fig. 27B).
Example 15: validation of the Effect of Using lactococcus lactis on the acceleration of wound healing
To show that local and continuous delivery of specific chemokines produced by bacteria is important for mechanisms unrelated to bacterial strains, another strain was used to produce and deliver chemokines directly to the wound surface, lactococcus lactis was transformed with pllab 112(mLrCK 1). Bacteria were applied to full-thickness wounds of healthy mice once daily according to the same protocol as treatment with lactobacillus reuteri.
There was a clear trend that mCXCL121 a delivery accelerated wound closure (fig. 28) and reduced wound size and exposure in this model (fig. 29).
Example 16: by using mCXCL12 as delivered as a recombinant protein 1 alpha, mCCCL 17 and mYm1 treatment for wound closure Moderate effect of combination over time
To demonstrate that the mode of delivery and continuous protein production of lactic acid bacteria is important for the mechanism, murine recombinant mCXCL121 α, mCXCL17, mYm1 (200 ng total in 60 μ l, all RnD systems) or saline as control (10 μ l) was delivered daily to the wound for 10 minutes each for one hour.
For mCXCL121 a, delivery of 30ng to the peritoneal cavity induced a significant increase in immune cell recruitment within 3 hours, which is delivery of 200ng to 25 μm2Is considered to be the cause of the high dose.
When chemokines are administered as recombinant proteins at a single time point, high protease activity in the wound may degrade the chemokines and thus the proteins re-produced by the bacteria are required for increased wound closure. In addition, lactic acid bacteria may also provide beneficial local environments for wound healing (fig. 1B, 4, 5, 24, 30 and 31).
Example 17: comparison of the Effect of different treatments on wound closure in healthy mice
All the different treatments performed were analyzed for wound closure in healthy mice for the first 24 hours (fig. 32). It is clear that treatment with lactobacillus reuteri R2LC _ Luc or a low single dose CXCL121 α administered to the wound at one time point can affect healing during the first 24 hours. Although CXCL121 a, CXCL17 and Ym1 delivered to the wound surface every 10 minutes over an hour had a tendency to accelerate wound closure within the first 24 hours, this effect was more pronounced when CXCL121 a was continuously delivered to the wound surface within one hour by lactobacillus reuteri R2LC _ LrCK1. CXCL12 was delivered by dermal overexpression with adverse effects on 24 hour wound closure.
Example 18: accelerated wound healing at mucosal surfaces by Lactobacillus reuteri containing pLAB112_ mLrCK1.4
To test whether the local continuous delivery of CXCL12 to the wounded surface acted via the general mechanism of skin epithelium and intestinal epithelium, two experimental protocols for DSS-induced colitis were employed. DSS (sodium dextran sulfate) is known to induce trauma at the colonic mucosal surface (reference 16).
For the first protocol, mice were treated with lactobacillus reuteri gavage (1ml OD 0.5, spun and resuspended in 0.1ml) once daily for 14 days, while DSS was given on days 7-14 in drinking water. Since this lactobacillus reuteri strain employing this protocol colonizes the colon, the objective was to assess whether the presence of lactobacillus reuteri plb 112_ mLrCK1 in the colon was beneficial compared to lactobacillus reuteri plb 112_ Luc when causing colitis.
The second regimen was aimed at treating overt colitis, with mice given DSS in 1-8 days of drinking water and receiving lactobacillus reuteri three times a day by gavage on days 5-8.
The severity of colitis was assessed based on clinical parameters including weight loss, stool consistency and blood volume and was expressed using a Disease Activity Index (DAI), a scoring method described in detail by Cooper and colleagues (reference 16).
Similar improvements in DSS-induced colitis disease activity were obtained by pretreatment with lactobacillus reuteri plb 112_ Luc and plb 112_ lrck1.4 (figure 33), indicating that the effect was due to lactobacillus reuteri only.
In contrast, when lactobacillus reuteri pllab 112_ lrck1.4 was administered to mice with colitis, the disease progression was improved, which was not observed when treated with pllab 112_ Luc, indicating the effect of the delivered chemokines.
