TECHNICAL FIELD

The subject matter described herein relates to a composition of human-derived bacteria that induces proliferation of T helper 17 (Th17) cells and which comprises, as an active component, human-derived bacteria, preferably (a) one or more bacteria isolated and cultured from the ampicillin-resistant bacterial fraction of a fecal sample or, (b) a culture supernatant of one or more bacteria of (a). It also relates to a method for inducing proliferation of Th17 cells. The composition, which comprises any of (a)-(b) above, is referred to as a bacterial composition. Moreover, the subject matter relates to a method for treating or preventing at least one disease or condition that is responsive to induction of Th17 cells, such as infectious diseases, by oral administration of the bacterial composition alone or in combination with an antigen to an individual in need thereof.

BACKGROUND

Hundreds of species of commensal microorganisms are harbored in the gastrointestinal tracts of mammals, where they interact with the host immune system. Research using germ-free (GF) animals has shown that the commensal microorganisms influence the development of the mucosal immune system, such as histogenesis of Peyer's patches (PPs) and isolated lymphoid follicles (ILFs), secretion of antimicrobial peptides from the epithelium, and accumulation of unique lymphocytes in mucosal tissues, including immunoglobulin A-producing plasma cells, intraepithelial lymphocytes, IL-17-producing CD4-positive T cells (Th 17), and IL-22-producing NK-like cells (Non-Patent Literature (NPL) 1 to 7). Consequently, the presence of intestinal bacteria enhances protective functions of the mucous membranes, enabling the host to mount robust immune responses against pathogenic microbes invading the body. On the other hand, the mucosal immune system maintains unresponsiveness to dietary antigens and harmless microbes (NPL Document 3). Abnormality in the regulation of cross-talk between commensal bacteria and the immune system (intestinal dysbiosis) may lead to overly robust or insufficiently robust immune responses to environmental antigens and to commensal and pathogenic microbes, resulting in disease (NPL 8 to 10). Better approaches to enabling the body to mount an effective immune response to invading pathogenic microbes are needed.

As described herein, although most bacterial species among the more than a thousand species present in the human microbiota do not have the ability to stimulate Th17 cells, the inventors have obtained, from humans, a few bacterial species that have the ability to cause a robust induction of Th17 cells, by modifying fecal samples derived from humans with various antibiotic treatments, applying methods to isolate pure strains in vitro, and developing culturing methods to manufacture bacterial compositions containing the strains that are suitable for use as pharmaceuticals and as food ingredients. Moreover, the inventors have shown that inoculating animals with the in vitro cultured species also leads to a robust accumulation of Th17 cells.

Effects of Invention

The compositions described herein are excellent at inducing the proliferation or accumulation of T helper 17 cells (Th17 cells). Immunity in an individual can be promoted through administration of the subject composition, such as through ingestion of the bacterial composition in a food or beverage or as a dietary supplement or through administration of a pharmaceutical composition comprising the bacterial composition. The subject composition can be used, for example, to prevent or treat infectious diseases, as well as in combination with mucosal vaccines to prevent diseases caused by microorganisms or the like. In addition, if a food or beverage, such as a health food, comprises the subject composition, healthy individuals can ingest the composition easily and routinely. As a result, it is possible to induce the proliferation and/or accumulation of Th17 cells and thereby improve immune functions.
The compositions described herein provide for a potent, long-lasting, patient-friendly, and benign treatment alternative for infectious diseases. For example, infectious disease is often managed with antibiotics that may lead to antibiotic-resistance and/or opportunistic infection; systemic vaccines require extensive purification due to their injectable nature, which risks spreading blood-borne infections and are not practical for mass vaccination; existing mucosal vaccines fail to achieve sufficiently strong immune responses and are often not as stable as a live attenuated formulation.
The compositions described herein, used in combination with a mucosal vaccine antigen, can also have an effect of increasing the immune response against the antigen, or extending the duration of the immune response against the antigen, or enabling a reduction of the dose and frequency of administration of the antigen (for example, reducing the number of booster injections of antigen-containing composition) required to achieve protection, or increasing the proportion of patients achieving seroconversion, or eliciting optimal immune responses in patients in which other vaccination strategies are not effective (for example, young or aging populations).

DESCRIPTION OF EMBODIMENTS

Recent studies have shown that individual commensal bacteria control differentiation of their specific immune cells in the mucosal immune system. For example, segmented filamentous bacteria, which are intestinal commensal bacteria in mice, induce mucosal Th17 cell response and enhance resistance against infection of gastrointestinal tracts of the host with a pathogen (NPL 11 to 13). Although specific species of murine bacterial commensals, such as segmented filamentous bacteria, that can strongly stimulate Th17 cells have been identified (NPL 11 to 13), it is still unknown whether species of human commensal bacteria exert an equivalent influence on the human immune system. Furthermore, the human intestinal tract harbors more than a thousand bacterial species, many of which have not yet been cultured (NPL 14). It is not feasible to guess a priori which ones, if any, might have an effect on Th17 cells.
In order to develop drugs, vaccines, dietary supplements, or foods with beneficial immune functions for human use, it is desirable to identify commensal microorganisms that naturally colonize humans and have immune-modulating properties. Furthermore, since many of the commensals in the human microbiome have yet to be cultured, it is necessary to develop methods to cultivate them so that they can be produced by industrial fermentation processes and subsequently incorporated in pharmaceutical or food formulations.
T helper 17 (Th17) cells are a subset of CD4⁺ T helper cells that provide anti-microbial immunity at mucosal surfaces, which can be critical for defense against microorganisms such as bacteria and fungi. Th17 cells depend on TGF-beta and IL-6 for differentiation and are defined by the lineage-specific transcription factor RORgt (NPL 11, 15, and 16). RORgt-expressing Th17 cells are present in large numbers in the gastrointestinal tract (NPL 6, 17). Memory CD4+ and CD8+ T cells can also be generated as a result of mucosal vaccination. In particular, memory Th17 cells with protective functions can be induced by mucosal vaccination (NPL 18).
Many infectious diseases are restricted to the mucosal membranes, or the infectious agent needs to cross the mucosal membrane during the early stages of infection. Therefore, it is desirable to obtain not only a systemic, but also a localized mucosal immune response as a result of vaccination, which can enhance protection against the infection. Vaccines administered by the mucosal route could thus be particularly effective in protecting against mucosal pathogens. However, existing mucosal vaccines are limited in their ability to promote robust immune responses at the mucosa, because exposure to antigens is not sufficiently prolonged, because the amount of antigens provided is insufficient to trigger a robust response, or because the antigens are not sufficiently immunogenic or stable. Partly because of these reasons, most vaccines used currently are still administered via the parenteral route. When host immune responses to an immunogenic antigen are too weak, it may be necessary to enhance them by co-administering an adjuvant.
Accordingly, human-derived commensal bacterial compositions with the ability to strongly induce Th17 cells are needed, as are methods to manufacture such compositions. Such compositions can be used to enable the host to mount robust immune responses against pathogenic microbes invading the body, and thus be applied as anti-infectives or as adjuvants of mucosal vaccines.
The term “T helper 17 cells (Th17 cells)” refers to T cells that promote an immune response and play a role in immune defense. Th17 cells are typically transcription factor RORgt-positive CD4-positive T cells. The Th17 cells of the present invention also include transcription factor RORgt-negative T cells that are IL-17-producing CD4-positive T cells.
The term “induces proliferation or accumulation of Th17 cells” refers to an effect of inducing the differentiation of immature T cells into Th17 cells, which differentiation leads to the proliferation and/or the accumulation of Th17 cells. Further, the meaning of “induces proliferation or accumulation of Th17 cells” includes in-vivo effects, in vitro effects, and ex vivo effects. All of the following effects are included: an effect of inducing in vivo proliferation or accumulation of Th17 cells through administration or ingestion of the aforementioned bacteria, or a culture supernatant of the bacteria or supernatant component(s); an effect of inducing proliferation or accumulation of cultured Th17 cells by causing the aforementioned bacteria or a culture supernatant of the bacteria or supernatant component(s) to act on the cultured Th17 cells; and an effect of inducing proliferation or accumulation of Th17 cells which are collected from a living organism and which are intended to be subsequently introduced into a living organism, such as the organism from which they were obtained or another organism, by causing the aforementioned bacteria, a culture supernatant of the bacteria or supernatant component(s), or a physiologically active substance derived from the bacteria to act on the Th17 cells. The effect of inducing proliferation or accumulation of Th17 cells can be evaluated, for example, as follows. Specifically, the aforementioned bacteria, a culture supernatant of the bacteria or supernatant component(s), or a physiologically active substance derived from the bacteria is orally administered to an experimental animal, such as a germ-free mouse, then CD4-positive cells in the gastrointestinal tract are isolated, and the ratio of Th17 cells contained in the CD4-positive cells is measured by flow cytometry.
The Th17 cells whose proliferation or accumulation is induced by the composition of the present invention are preferably transcription factor RORgt-positive Th17 cells or IL-17-producing Th17 cells.
In the present invention, “human-derived bacteria” means bacterial species that have been isolated from a fecal sample or from a gastrointestinal biopsy obtained from a human individual or whose ancestors were isolated from a fecal sample or from a gastrointestinal biopsy obtained from a human (e.g., are progeny of bacteria obtained from a fecal sample or a gastrointestinal biopsy). For example, the bacterial species may have been previously isolated from a fecal sample or from a gastrointestinal biopsy obtained from a human and cultured for a sufficient time to generate progeny. The progeny can then be further cultured or frozen.
In the present invention, the term “immune response” signifies any reaction produced by an antigen, such as a protein antigen, in a host having a functioning immune system. Immune responses may be humoral, involving production of immunoglobulins or antibodies, or cellular, involving various types of B and T lymphocytes, dendritic cells, macrophages, antigen presenting cells and the like, or both Immune responses may also involve the production or elaboration of various effector molecules such as cytokines.

Described herein is a composition that induces proliferation, accumulation of Th17 cells or both proliferation and accumulation of Th17 cells. The composition comprises, as an active ingredient, one or more of the following: an (at least one, one or more) organism (bacteria) selected from the group consisting of: Clostridium symbiosum (SEQ ID No 16), Clostridium hathewayi (SEQ ID No 12), Clostridium citroniae (SEQ ID No 20), Clostridium bolteae (SEQ ID No 19), Ruminococcus sp. M-1 (SEQ ID No 14), Ruminococcus gnavus (SEQ ID No 9), Blautia sp. canine oral taxon 143 (SEQ ID No 4), Anaerostipes caccae (SEQ ID No 18), Clostridium lactatifermentans (SEQ ID No 3), Coprobacillus cateniformis (SEQ ID No 15), Clostridium ramosum (SEQ ID No 1), cf. Clostridium sp. MLG055 (SEQ ID No 5), Clostridium innocuum (SEQ ID No 6), Eubacterium desmolans (SEQ ID No 11), Clostridium orbiscindens (SEQ ID No 7), Ruminococcus sp. 16442 (SEQ ID No 8), Anaerotruncus colihominis (SEQ ID No 10), Bacteroides dorei (SEQ ID No 17), Bifidobacterium pseudolongum subsp. Pseudolongum (SEQ ID No 2), and Bifidobacterium breve (SEQ ID No 13), a culture supernatant of one or more of the bacteria, a component of culture medium in which a (at least one, one or more) bacterium described herein has grown; and a (at least one; one or more) bacterium containing DNA comprising a nucleotide sequence having at least 97% homology to the nucleotide sequence of DNA of any of the bacterial species described herein, such as those listed above. Bacteria described herein were isolated from human fecal samples using the methods outlined in Examples 1 to 3.
The bacterial composition or pharmaceutical composition may include one strain alone (only one strain) of any of the bacterial species listed or described herein; two or more strains of the bacteria can be used together. For example, one, two, three, four, five, six, seven, eight, nine, ten, eleven, twelve, thirteen, fourteen, fifteen, sixteen, seventeen, eighteen, nineteen, or twenty of the strains listed in Table 1, in any combination, can be used together to affect Th17 cells.
If more than one strain of bacteria is used, the number and ratio of strains used can vary widely. The number and ratio to be used can be determined based on a variety of factors (e.g., the desired effect, such as induction or inhibition of proliferation or accumulation of Th17 cells; the disease or condition to be treated, prevented or reduced in severity; the age or gender of the recipient; the typical amounts of the strains in healthy humans). The strains can be present in a single composition, in which case they can be consumed or ingested together (in a single composition), or can be present in more than one composition (e.g., each can be in a separate composition), in which case they can be consumed individually or the compositions can be combined and the resulting combination (combined compositions) consumed or ingested. Any number or combination of the strains that proves effective (e.g., any number from one to 20, such as 1 to 20, 1 to 15, 1 to 10, 1 to 5, 1 to 3, 1 to 2, and any number therebetween can be administered. In certain embodiments of the present invention, a combination of some or all of the 20 (e.g., the 20 strains in Table 1) strains described in the present disclosure is used. For example, at least one, two or more, three, three or more, four, four or more, five, five or more, six, six or more or any other number of the 20 described strains, including 20 strains, can be used. They can be used in combination with one another and in combination with strains not described in the cited reference.
When the aforementioned bacterial compositions are cultured in a medium, substances contained in the bacteria, secretion products and metabolites produced by the bacteria are released from the bacteria. The meaning of active ingredient “culture supernatant of the bacteria” in the composition includes such substances, secretion products, and metabolites. The culture supernatant is not particularly limited, as long as the culture supernatant has the effect of inducing proliferation or accumulation of Th17 cells. Examples of the culture supernatant include a protein fraction of the culture supernatant, a polysaccharide fraction of the culture supernatant, a lipid fraction of the culture supernatant, and a low-molecular weight metabolite fraction of the culture supernatant.
The bacterial strains in the bacterial compositions may be administered in live form, or they may be administered in attenuated, inactivated, or killed form (for example, heat-killed).
The bacterial composition may be administered in the form of a pharmaceutical composition, a dietary supplement, or a food or beverage (which may also be an animal feed), or may be used as a reagent for an animal model experiment. The pharmaceutical composition, the dietary supplement, the food or beverage, and the reagent induce proliferation or accumulation of Th17 cells. Examples presented herein revealed that the bacterial composition induced Th17 cells when administered to animals. The composition of the present invention can be used suitably as a composition having an effect of promoting an immune response.
The bacterial composition of the present invention can be used, for example, as a pharmaceutical composition for preventing or treating (reducing, partially or completely the adverse effects of) an infectious disease, such as a bacterial infection, a viral infection, a parasitic infection, and a fungal infection. Oral administration of the newly identified compositions and their subsequent colonization of the gastrointestinal tract induces Th17 cells at the mucosal surface. These Th17 cells mediate protective immune responses at mucosal surfaces against a number of infectious agents, including bacteria, viruses, fungi, and parasites.

The bacterial composition may be administered as an adjuvant in combination with antigenic material. The antigenic material can include one or more portions of the protein coat, protein core, or functional proteins and peptides of a pathogen, or a full pathogen (live, killed, inactivated, or attenuated), or may comprise one or a plurality of cancer epitopes or cancer antigens. The antigenic material can be co-administered, administered before, or after the bacterial composition. The bacterial composition may also be administered with existing mucosal vaccines such as influenza vaccines, (e.g. FluMist from Medlmmune or NASOVAC from Serum Institute of India), rotavirus vaccines (e.g. RotaTeq from Merck or Rotarix from GlaxoSmithKline), typhoid vaccines (e.g. Vivotif from Crucell, Ty21A), cholera vaccines (e.g. Orochol from Crucell, Shanchol from Shantha Biotechnics), traveller's diarrhea vaccines (e.g. Dukoral from Crucell), and with antigens of live attenuated Influenza A virus H1 strain, live attenuated Influenza A virus H3 strain, Influenza B virus, live attenuated H1N1 influenza virus (swine flu), live attenuated rotavirus, mono- and multi-valent poliovirus, live attenuated Salmonella typhi, live recombinant Vibrio cholerae lacking cholera toxin subunit A, whole killed Vibrio cholerae 01 classical and El Tor biotypes with or without cholera toxin subunit B, cancer antigens, cancer epitopes, and combinations thereof.
The bacterial composition can be engineered to express specific antigens from selected pathogens or cancer antigens using genetic engineering methods well known to those skilled in the art and used, for example, as a pharmaceutical composition for prolonging exposure to said antigens and inducing stronger mucosal immune responses than oral administration of the soluble antigens alone. In one embodiment, an organism from Table 1 can be engineered by incorporation of an expression vector expressing a heterologus antigen. Said heterologous antigens may include, but are not limited to, influenza HA, NA, M2, HIV gp120, Mycobacterium tuberculosis Ag85B and ESAT6, Streptococcus pneumonia PspA, PsaA, and CbpA, respiratory syncytial virus (RSV) F and G protein, human papilloma virus protein, and cancer antigens. Furthermore, the Th-17 inducing strains can also be engineered to have a limited capacity for replication in the host, while delivering a sufficiently high antigen load at the site of immunization, so that long-term colonization by the strains is avoided.
The bacterial composition described herein and other Th17-inducing strains can be inhibited for use in preventing or treating (reducing, partially or completely, the adverse effects of) autoimmune and inflammatory diseases. Th17 cells can also have the deleterious effect of promoting chronic autoimmune and inflammatory responses in the host. Accordingly, methods of inhibiting the Th17-inducing strains via administration of molecules that impair their growth and/or function, or directly kill the Th17-inducing strains, can be used for treating autoimmune and inflammatory diseases mediated by Th17 responses. Antibiotics including, but not limited to, vancomycin and metronidazole, can be used to inhibit the Th17-inducing strains. Target diseases for which inhibition of the Th17-inducing strains is useful for treatment include: inflammatory bowel disease (IBD), ulcerative colitis, Crohn's disease, sprue, autoimmune arthritis, rheumatoid arthritis, Type I diabetes, multiple sclerosis, osteoarthritis, systemic lupus erythematosus, insulin dependent diabetes mellitus, asthma, psoriasis, atopic dermatitis, graft versus host disease, acute or chronic immune disease associated with organ transplantation, sarcoidosis, atherosclerosis, atopic allergy, food allergies such as peanut allergy, tree nut allergy, egg allergy, milk allergy, soy allergy, wheat allergy, seafood allergy, shellfish allergy, or sesame seed allergy, allergic rhinitis (pollen allergies), anaphylaxis, pet allergies, latex allergies, drug allergies, allergic rhinoconjuctivitis, eosinophilic esophagitis, and diarrhea, among others.
Pharmaceutical preparations can be formulated from the bacterial compositions described by drug formulation methods known to those of skill in the art. For example, the composition can be used orally in the form of capsules, tablets, pills, sachets, liquids, powders, granules, fine granules, film-coated preparations, pellets, troches, sublingual preparations, chewables, buccal preparations, pastes, syrups, suspensions, elixirs, and emulsions, or it can be used in a suppository or an enema.
Pharmaceutical preparations for use in mucosal vaccination can be formulated in oral form such as a solution, suspension, or emulsion in an aqueous or oil solvent, or dried as a powder. In addition, depending on the purpose, buffers, isotonizing agents, soothing agents, preservative agents, or anti-oxidants, may be added to the mucosal vaccine formulation.
For formulating these preparations, the bacterial compositions can be used in appropriate combination with carriers that are pharmacologically acceptable or acceptable for ingestion, such as in a food or beverage, including one or more of the following: sterile water, physiological saline, vegetable oil, solvent, a base material, an emulsifier, a suspending agent, a surfactant, a stabilizer, a flavoring agent, an aromatic, an excipient, a vehicle, a preservative, a binder, a diluent, a tonicity adjusting agent, a soothing agent, a bulking agent, a disintegrating agent, a buffer agent, a coating agent, a lubricant, a colorant, a sweetener, a thickening agent, a flavor corrigent, a solubilizer, and other additives.
A pharmaceutical preparation or formulation and particularly a pharmaceutical preparation for oral administration, can comprise an additional component that enables efficient delivery of the bacterial composition of the present invention to the colon, in order to more efficiently induce proliferation or accumulation of Th17 in the colon. A variety of pharmaceutical preparations that enable the delivery of the bacterial composition to the colon can be used. Examples thereof include pH sensitive compositions, more specifically, buffered sachet formulations or enteric polymers that release their contents when the pH becomes alkaline after the enteric polymers pass through the stomach. When a pH sensitive composition is used for formulating the pharmaceutical preparation, the pH sensitive composition is preferably a polymer whose pH threshold of decomposition is between about 6.8 and about 7.5. Such a numeric value range is a range in which the pH shifts toward the alkaline side at a distal portion of the stomach, and hence is a suitable range for use in the delivery to the colon.
Another embodiment of a pharmaceutical preparation useful for delivery of the bacterial composition to the colon is one that ensures the delivery to the colon by delaying the release of the contents (e.g., the bacterial composition) by approximately 3 to 5 hours, which corresponds to the small intestinal transit time. In one embodiment of a pharmaceutical preparation for delayed release, a hydrogel is used as a shell. The hydrogel is hydrated and swells upon contact with gastrointestinal fluid, with the result that the contents are effectively released (released predominantly in the colon). Delayed release dosage units include drug-containing compositions having a material which coats or selectively coats a drug or active ingredient to be administered. Examples of such a selective coating material include in vivo degradable polymers, gradually hydrolyzable polymers, gradually water-soluble polymers, and/or enzyme degradable polymers. A wide variety of coating materials for efficiently delaying the release is available and includes, for example, cellulose-based polymers such as hydroxypropyl cellulose, acrylic acid polymers and copolymers such as methacrylic acid polymers and copolymers, and vinyl polymers and copolymers such as polyvinylpyrrolidone.
Examples of the composition enabling the delivery to the colon further include bioadhesive compositions which specifically adhere to the colonic mucosal membrane (for example, a polymer described in the specification of U.S. Pat. No. 6,368,586) and compositions into which a protease inhibitor is incorporated for protecting particularly a biopharmaceutical preparation in the gastrointestinal tracts from decomposition due to an activity of a protease.
The bacterial composition can be used as a food or beverage, such as a health food or beverage, a food or beverage for travelers, for infants, pregnant women, athletes, senior citizens or other specified group, a functional food, a food or beverage for specified health use, a dietary supplement, a food or beverage for patients, or an animal feed.
The addition of the bacterial composition to an antibiotic-free animal feed makes it possible to increase the body weight of an animal that ingests the animal feed to a level equal to or higher than that achieved by ingestion of antibiotic-containing animal feeds, and also makes it possible to reduce pathogenic bacteria in the gastrointestinal tract to a level equal to those in animals consuming typical antibiotic-containing animal feeds. The bacterial composition can be used as a component of an animal feed that does not need the addition of antibiotics. Animal feed comprising the bacterial composition can be fed to a wide variety of types of animals and animals of a varying ages and can be fed at regular intervals or for a certain period (for example, at birth, during weaning, or when the animal is relocated or shipped).
The bacterial active components of the bacterial composition can be manufactured using fermentation techniques. In one embodiment, the bacterial active components are manufactured using anaerobic fermentors, which can support the rapid growth of bacterial strains. The anaerobic fermentors may be, for example, stirred tank reactors or disposable wave bioreactors. Culture media such as BL agar, or similar versions of these media devoid of animal components can be used to support the growth of the bacterial species. The bacterial product can be purified and concentrated from the fermentation broth by techniques such as centrifugation and filtration, and can optionally be dried and lyophilized.
The amount of the bacterial composition to be administered or ingested can be determined empirically, taking into consideration such factors as the age, body weight, gender, symptoms, health conditions, of an individual who will receive it, as well as the kind of bacterial composition (a pharmaceutical product, a food or beverage) to be administered or ingested. For example, the amount per administration or ingestion is generally 0.01 mg/kg body weight to 100 mg/kg body weight, and, in specific embodiments, 1 mg/kg body weight to 10 mg/kg body weight. Also described herein is a method for promoting immunity (potentiating the immune response) of a subject, the method being characterized in that the bacterial compostions is administered to or ingested by the subject as described above.
The bacterial composition may be administered to an individual once, or it may be administered more than once. If the composition is administered more than once, it can be administered on a regular basis (for example, once a day, once every two days, once a week, once every two weeks, once a month, once every 6 months, or once a year) or on an as needed or irregular basis. The appropriate frequency of administration (which may depend on host genetics, age, gender, and health or disease status of the subject, among other factors) may be determined empirically. For example, a patient can be administered one dose of the composition, and the levels of the bacterial strains of the composition in fecal samples obtained from the patient can be measured at different times (for example, after 1 day, after 2 days, after 1 week, after 2 weeks, after 1 month). When the levels of the bacteria fall to, for example, one half of their maximum post-dose value, a second dose can be administered, and so on.
A product comprising the bacterial composition (a pharmaceutical product, a food or beverage, or a reagent) or a manual thereof may be accompanied by document or statement explaining that the product can be used to promote immunity (including a statement that the product has an effect of promoting immunity and a statement that the product has an effect of promoting the proliferation or function of Th17 cells). Here, the “provision to the product or the manual thereof with the note” means that the document or statement is provided to a main body, a container, a package, or the like of the product, or the note is provided to a manual, a package insert, a leaflet, or other printed matters, which disclose information on the product.

As described above, and as shown in Examples 1 to 3, administration of the bacterial composition to an individual makes it possible to induce proliferation or accumulation of Th17 cells in the individual. This provides a method of inducing proliferation or accumulation of Th17 cells in an individual, the method comprising: administering, to the individual, at least one member selected from the group consisting of: (a) Clostridium symbiosum, Clostridium hathewayi, Clostridium citroniae, Clostridium bolteae, Ruminococcus sp. M-1, Ruminococcus gnavus, Blautia sp. canine oral taxon 143, Anaerostipes caccae, Clostridium lactatifermentans, Coprobacillus cateniformis, Clostridium ramosum, cf. Clostridium sp. MLG055, Clostridium innocuum, Eubacterium desmolans, Clostridium orbiscindens, Ruminococcus sp. 16442, Anaerotruncus colihominis, Bacteroides dorei, Bifidobacterium pseudolongum subsp. Pseudolongum, and Bifidobacterium breve; (b) a culture supernatant of at least one (a, one or more) of the bacteria described/listed herein; or a combination of (a) and (b). The bacterial composition is administered (provided) to the individual in sufficient quantity to produce the desired effect of inducing proliferation, accumulation or both proliferation and accumulation of Th17 cells. It may be administered to an individual in need of treatment or reduction in the severity of an infectious disease. It may also be administered to an individual in need of prevention of an infectious disease, as an adjuvant of a mucosal vaccine formulation.
Note that, the “individual” or “subject” (e.g., a human) may be in a healthy state or a diseased state. The method may further comprise the optional step of administering at least one (a, one or more) antibiotic preceding, or in combination with, the bacterial composition.
Moreover, a prebiotic composition can be used to favor the growth of the species in the bacterial composition over the growth of other human commensal bacterial species. In one embodiment, the prebiotic substance(s) is a nondigestible oligosaccharide. A method of inducing proliferation and/or accumulation of Th17 in an individual can comprise administering, to the individual, at least one prebiotic or at least one antibiotic in combination with the bacterial composition. Also contemplated herein is a composition comprising the bacterial composition and a prebiotic composition or an antibiotic composition.
There is no particular limitation imposed on the combined use of the therapeutic composition with at least one substance selected from the group consisting of the bacterial composition, the “mucosal vaccine formulation”, the “mucosal vaccine antigen”, the “antibiotic”, and the “prebiotic composition”. For example, the “one substance” and the therapeutic composition are administered orally or parenterally to an individual simultaneously or sequentially/individually at any appropriate time.
Whether administration of the bacterial composition induces the proliferation and/or accumulation of Th17 cells can be determined by using, as an index, increase or reinforcement of at least one of the following: the number of Th17 cells, the ratio of Th17 cells in the T cell group of the gastrointestinal tract, a function of Th17 cells, or expression of a marker of Th17 cells. A specific approach is measurement counts or percentage of RORgt-expressing Th17 cells in a patient sample, such as a biopsy or a blood sample, promotion (enhancement) of IL-17 expression, or colonization of an individual with the bacterial composition administered as the index of the induction of proliferation or accumulation of Th17 cells. Methods for detecting such expression include northern blotting, RT-PCR, and dot blotting for detection of gene expression at the transcription level; ELISA, radioimmunoassays, immunoblotting, immunoprecipitation, and flow cytometry for detection of gene expression at the translation level. Samples that may be used for measuring such an index include tissues and fluids obtained from an individual, such as blood, obtained in a biopsy, and a fecal sample.

Also provided is a method of monitoring a subject's (e.g., a human's) response to treatment with the bacterial compositions described herein, comprising: (a) obtaining a (one or more, at least one) sample, such as a fecal sample or a colonic biopsy from a patient before treatment with a bacterial composition described herein; (b) obtaining, a (one or more, at least one) corresponding sample from the patient after treatment with a bacterial composition described herein; and (c) comparing the percentage or absolute counts of at least one bacterial species selected from the group consisting of: Clostridium symbiosum, Clostridium hathewayi, Clostridium citroniae, Clostridium bolteae, Ruminococcus sp. M-1, Ruminococcus gnavus, Blautia sp. canine oral taxon 143, Anaerostipes caccae, Clostridium lactatifermentans, Coprobacillus cateniformis, Clostridium ramosum, cf. Clostridium sp. MLG055, Clostridium innocuum, Eubacterium desmolans, Clostridium orbiscindens, Ruminococcus sp. 16442, Anaerotruncus colihominis, Bacteroides dorei, Bifidobacterium pseudolongum subsp. Pseudolongum, and Bifidobacterium breve in the sample obtained in (a) with the percentage or absolute counts of the same at least one bacterial species in the sample obtained in (b), wherein a higher value in the sample obtained in (b) (after treatment with the bacterial composition) than in the sample obtained in (a) (before treatment) indicates that the subject has responded favorably to treatment (e.g., is a positive indicator of enhanced immune response in the subject). In some embodiments, the method further comprises (d) further administering the bacterial composition to the patient or ceasing administration of the bacterial composition to the patient based on the comparison in (c). In the monitoring method described herein, a variety of known methods can be used for determining the percentage or absolute counts of a bacterial species. For example, 16S rRNA sequencing can be used.

Certain modifications applied to a fecal sample can result in the obtention of Th17-inducing bacterial compositions. Surprisingly, administration of ampicillin to animals enriches the representation of Th17-inducing strains in a sample. Culturing serially diluted samples from ampicillin-treated animals by plating under strictly anaerobic conditions in certain media described in Example 2 led to obtention of potent Th17-inducing bacterial compositions. Accordingly, provided is a method of obtaining Th17-inducing bacterial compositions, comprising (a) treating a subject with the antibiotic ampicillin, or an antibiotic with a similar spectrum, for example an aminopenicillin family member such as amoxicillin, penicillin, or benzylpenicillin; (b) obtaining (a, one or more, at least one) sample, such as a fecal sample or an intestinal biopsy from the subject; (c) culturing the sample from (b) and isolating pure bacterial strains from the resulting colonies. In a preferred embodiment the subject in (a) is an ex-germ-free animal that is first colonized with a fecal sample obtained from a human donor, and afterwards is treated with ampicillin, after which cecal samples are obtained from the animal and cultured as described in Example 2. In one embodiment, the isolation of pure bacterial strains of (c) is performed by serial dilutions of cecal content samples cultured by plating under a strictly anaerobic condition. In another embodiment, the method comprises (a) obtaining (at least one) sample, such as a fecal sample or an intestinal biopsy from a subject; (b) treating the sample of (a) with ampicillin; (c) culturing the ampicillin-treated sample of (b) and isolating pure bacterial strains.

The bacterial composition can be administered to an individual who is also receiving antibiotic treatment. The present inventors have demonstrated that antibiotics such as vancomycin or metronidazole can effectively eliminate or greatly reduce Th17-inducing bacterial species from the gastrointestinal tract of mammals and subsequently decrease the levels of Th17 cells (Example 1). Without wishing to be bound by theory, the key role of Th17-inducing bacteria promoting immune responses strongly indicates that their presence or high levels can play a key role in autoimmune diseases. Accordingly, individuals undergoing courses of antibiotics such as vancomycin or metronidazole, who are at a high risk of experiencing a loss of Th17-inducing bacteria and thus experience immune deficits, can be preventively “repopulated” through use of the bacterial compositions. The bacterial compositions can be administered before, simultaneously with, or after the antibiotic treatment, but preferably are administered simultaneously or after the antibiotic treatment.
Following are examples, which describe specific aspects. They are not intended to be limiting in any way.

EXAMPLES

Example 1

Human stool (2 g) from an ulcerative colitis (UC) Japanese patient in a clinically active state was suspended with 8 ml phosphate-buffered saline (PBS) containing 20% glycerol, snap-frozen in liquid nitrogen, and stored at −80° C. until use. The frozen stock was thawed, and orally inoculated into IQI germ-free (GF) mice (250 μl/mouse). The mice were given ampicillin (ABPC; 1 g/L), vancomycin (VCM; 500 mg/L), polymyxin B (PL-B; 200 mg/L), metronidazole (MNZ; 1 g/L), or water only (non-treated: NT) in their drinking water beginning 1 d after the inoculation with UC patient feces until the day of analysis. Each group of ex-GF mice (n=5 for each group) was separately kept in a vinyl isolator for 4 weeks.
The colons were collected and opened longitudinally, washed with PBS to remove all luminal contents and shaken in Hanks' balanced salt solution (HBSS) containing 5 mM EDTA for 20 mM at 37° C. After removing epithelial cells, muscle layers and fat tissue using forceps, the lamina propria layers were cut into small pieces and incubated with RPMI1640 containing 4% fetal bovine serum (FBS), 0.5 mg/mL collagenase D, 0.5 mg/mL dispase and 40 mg/mL DNase I (all Roche Diagnostics) for 1 h at 37° C. in a shaking water bath. The digested tissues were washed with HBSS containing 5 mM EDTA, resuspended in 5 mL of 40% Percoll (GE Healthcare) and overlaid on 2.5 ml of 80% Percoll in a 15-ml Falcon tube. Percoll gradient separation was performed by centrifugation at 800 g for 20 mM at 25° C. The lamina propria lymphocytes were collected from the interface of the Percoll gradient and suspended in RPMI1640 containing 10% FBS. For analysis of Th1 and Th17 cells, isolated lymphocytes were stimulated for 4 h with 50 ng/mL phorbol 12-myristate 13-acetate (PMA, Sigma) and 750 ng/mL ionomycin (Sigma) in the presence of GolgiStop (BD Biosciences). After incubation for 4 h, cells were washed in PBS, labelled with the LIVE/DEAD fixable dead cell stain kit (Invitrogen) and surface CD4 and CD3 were stained with PECy7-labelled anti-CD4 Ab (RM4-5, BD Biosciences) and BV605-labelled anti-CD3 Ab (17A2, BioLegend). Cells were washed, fixed and permeabilized with Foxp3 Staining Buffer set (eBioscience), and stained with the APC-labelled anti-IL-17 Ab (eBio17B7, eBioscience) and BV421-labelled anti-IFN-g Ab (XMG1.2, BioLegend). The Ab stained cells were analyzed with LSR Fortessa (BD Biosciences), and data were analyzed using FlowJo software (Treestar).
In mice orally inoculated with UC patient feces, substantial induction of Th17 cells was observed. Surprisingly, the Th17 induction was enhanced in mice given ampicillin (ABPC) in the drinking water, compared with mice given water only (non-treated: NT). In contrast, Th17 induction was significantly impaired by the treatment with vancomycin (VCM) or metronidazole (MNZ). On the other hand, treatment with polymyxin B (PL-B) did not affect Th17 cell numbers (FIG. 1).
Therefore, Th17-inducing bacteria are present in the human feces, and the bacterial species are resistant to ampicillin and polymyxin B, but sensitive to vancomycin and metronidazole.

Example 2

The caecal contents from each exGF mice described in Example 1 were suspended in 10 mL of Tris-EDTA containing 10 mM Tris-HCl and 1 mM EDTA (pH 8), and incubated with Lysozyme (SIGMA, 15 mg/mL) at 37° C. for 1 h with gentle mixing. A purified achromopeptidase (Wako) was added (final concentration 2000 unit/mL) and incubated at 37° C. for another 30 min. Then, sodium dodecyl sulfate (final concentration 1%) was added to the cell suspension and mixed well. Subsequently, proteinase K (Merck) was added (final concentration 1 mg/mL) to the suspension and the mixture was incubated at 55° C. for 1 h. High-molecular-weight DNA was isolated and purified by phenol/chloroform extraction, ethanol, and finally polyethyleneglycol precipitation. PCR was performed using Ex Taq (TAKARA) and (i) modified primer 8F [5′-CCATCTCATCCCTGCGTGTCTCCGACTCAG (454 adaptor sequence, SEQ ID NO.: 21)+Barcode (10 bases)+AGRGTTTGATYMTGGCTCAG (SEQ ID NO.: 22)-3′] and (ii) modified primer 338R [5′-CCTATCCCCTGTGTGCCTTGGCAGTCTCAG (454 adaptor sequence, SEQ ID NO.: 23)+TGCTGCCTCCCGTAGGAGT (SEQ ID NO.: 24)-3′] to the V1-V2 region of the 16S rRNA gene. Amplicons generated from each sample (˜330 bp) were subsequently purified using AMPure XP (BECKMAN COULTER). The amount of DNA was quantified using Quant-iT Picogreen dsDNA Assay Kit (Invitrogen) and TBS-380mini Fluorometer (Turner Biosystems). Then, the amplified DNA was used as template for IonPGM sequencer. Resulting sequences (3000 reads were produced for each sample) were classified into OTUs based on sequence similarity (>96% identity). Representative sequences from each OTU were compared with sequences in nucleic acid databases (Ribosomal Database Project) or GenomeDB (NCBI+HMP+Hattori Lab data base) using BLAST to determine the closest strains.
OTUs negatively correlated with Th17 cell number are depicted in FIG. 2 in blue or grey, and OTUs positively correlated with Th17 cell number are marked with red.
Serial dilutions of the cecal contents from mice colonized with UC patient feces and given ampicillin were cultured by plating under a strictly anaerobic condition (80% N ₂10% H ₂10% CO₂) on BL agar (Eiken Chemical) supplemented with 5% defibrinated horse blood (Nippon Bio-Supp.Center), GAM agar (Nissui) supplemented with 5% defibrinated horse blood, Tryptic soy agar (Becton Dickinson) supplemented with 5% defibrinated horse blood, Reinforced clostridial agar (Oxoid) supplemented with 5% defibrinated horse blood, Schaedler agar (Becton Dickinson) or Brain Heart Infusion agar (Becton Dickinson). After culture at 37° C. for 2 days, each single colony was picked up (250 colonies in total) and stocked in Schaedler Broth (Becton Dickinson) containing 10% glycerol at −80° C. To identify the isolated strains, the 16S rRNA genes were amplified by colony-PCR using KOD FX (TOYOBO) and 16S rRNA gene-specific primer pairs: 8F (5′-AGAGTTTGATCMTGGCTCAG-3′) (SEQ ID NO.: 25) and 1492R (5′-GGYTACCTTGTTACGACTT-3′) (SEQ ID NO.: 26). The amplification program consisted of one cycle at 98° C. for 2 min, followed by 35 cycles at 98° C. for 10 s, 57° C. for 30s and 68° C. for 90s. Each amplified DNA was purified from the reaction mixture using AMPure XP. Sequence analysis was performed using BigDye Terminator V3.1 Cycle Sequencing Kit (Applied Biosystems) and Applied Biosystems 3730x1 DNA analyzer (Applied Biosystems). The resulting sequences were compared with sequences in the RDP database to determine the closest relatives. BLAST search of 16S rRNA gene sequences of these picked-up colonies revealed that we succeeded in isolating 20 strains (Table 1).

Example 3

To investigate whether the isolated 20 strains (Table 1) have the ability to induce Th17 cells, all 20 strains were cultured and mixed to make a cocktail, and the cocktail was orally inoculated into GF mice. The isolated 20 strains were individually cultured in Schaedler or PYG broth under a strictly anaerobic condition (80% N₂, 10% H₂, 10% CO₂) at 37° C. in an anaerobic chamber (Coy Laboratory Products), and then mixed at equal amounts of media volume to prepare the bacterial mixture. The aliquot of bacterial mixture was orally inoculated into mice (0.5 ml/mouse). After 4 weeks, the colons and small intestines were collected and analyzed for Th17 and Th1 cells. The percentages of IL-17+ cells and IFN-g+ within the CD4+T cell population in the colon lamina propria and small intestine lamina propria of the indicated mice are shown in FIG. 3. In mice colonized with the 20 strains, a strong induction of Th17 cells was observed.

INDUSTRIAL APPLICABILITY

As has been described above, the compositions and methods described herein make it possible to provide an excellent and well-characterized composition for inducing proliferation or accumulation of Th17 by utilizing certain human-derived bacteria or supernatants or the like derived from the bacteria. Since the bacterial composition has the effects of promoting immune responses, the bacterial composition can be used, for example, to treat infections, as well as to prevent infections as a component of a mucosal vaccine. In addition, healthy individuals can easily and routinely ingest the bacterial composition, such as in food or beverage, (e.g., a health food), to improve their immune functions.
This application is based on U.S. provisional patent application No. 61/978,182 (filing date: Apr. 10, 2014), the contents of which are incorporated in full herein.
