Those skilled in the art may use and adopt alternative methods to test the binding of such antibodies such as but not limited to scatchard analyses for cell binding, BIACORE analysis, Western blot analysis, or Dot blot analysis for antigen binding. Those skilled in the art may also use other Core-1 carrying molecules for testing a Core-1 binding such as (Gal betal-3 GalNAc alphal-) coupled with or without a suitable linker to KLH, biotin or BSA, however, the above described preferred embodiments are preferred in sense of the invention.

[0018] In accordance with the present invention the term "Core-1 positive microorganism" means any microorganism which is bound by at least one Core-1 specific antibody. In another embodiment said Core-1 positive microorganism is bound by at least two different lectins, a lectin is a carbohydrate binding molecule which is no antibody molecule, which is binding to Core-1.

In the most preferred embodiment said Core-1 positive microorganism is bound by NEMOD-TFI and NEM0D-TF2 or NEMOD-TFI and A76-G/A7 and the binding is periodate sensitive.

[0019] The methods for testing if a Core-1 specific antibody binds to a micoorgansim in this invention are ELISA and immunofluorescence (see examples), but those skilled in the art might use other test systems such as flow cytometry or several adsorption technique in order to identify Core-1 positive microorganisms.

[0020] The periodate treatment to test the periodate sensitivity of the binding of a Core-1 specific antibody towards a microorganism is described in detail in example 9. In accordance with the present invention the term "Core-1 periodate sensitivity of a microorganism" means that the binding of a Core-1 specific antibody to said microorganism is less or higher when said microorganism was treated with periodate than its binding to the same microorganism which was treated without periodate as described in detail in the examples. In a preferred embodiment said binding of a Core-1 specific antibody to said microorganism is less when said microorganism was treated with periodate than its binding to the same microorganism which was treated without periodate. In a more preferred embodiment said reduced binding of the Core-1 specific antibody to said microorganism after periodate treatment of the microorganism is less than 80% of the non-periodate treated counterpart, and even more preferred less than 50% and most preferred less than 30%.

In a preferred embodiment the Core-1 positive microorganism is a microorganism which originates from the human gastrointestinal system.

[0022] In accordance with the present invention the term fraction of a core-1-positive microorganism means preparations or purifications of smaller parts of said microorganisms such as cell wall preparation, envelope preparation, lysates, lipopolysaccharid preparation, preparation of capsules, or capsule polysaccharide preparation. They preferably comprise at least one Core-1 positive component of said Core-1 positive microorganism. They can be obtained by preparations or purifications from at least one Core-1 positive microorganism. Said preparations and purifications can be obtained by methods known to those skilled in the art such as those described above, or single or sequential cell fractionation, phenol water extractions, ether extractions, lysozyme digestions or chromatographic methods. The Core-1 positive component or the fraction containing the Core-1 positive component is detected by binding of the fraction to at least one Core-1 specific antibody in test systems such as but not limited to ELISA or Dot blots which are known to those skilled in the art. In a preferred embodiment of the invention the fraction comprising a Core-1 positive component is obtained by affinity chromatography using at least one Core-l specific antibody. In a preferred embodiment a single preparation or purification step is used. In another preferred embodiment a combination of at least two preparation or purification steps are used.

[0023] In accordance with the present invention the term Core-1 positive component means any component of a Core-1 positive microorganism which is bound by at least one Core-1 specific antibody. Said Core-1 positive component comprises at least one Core-1 carbohydrate structure or Core-1 mimicking structure which can be available in form of its natural molecule where it is part of on the microorganism, such as a peptide, oligopeptide, polypeptide, lipid, ceramide, carbohydrate, lipoprotein, polysaccharide, oligosaccharide, polysaccharide, proteoglycan or glycoprotein, or as a part of said natural molecule, or alone. The Core-1 I positive component can be used in sense of the invention as a fraction of the Core-1 positive microorganism as such or coupled to other non-natural carrier structures such as proteins, lipids, chemical molecules such as polyacrylamide. Preferably it is used in its natural form. The Core-1 positive component can comprise a single Core-1 carbohydrate structure or Core-1 mimicking structure or repeating units of said structures and can contain additional carbohydrate structures or units or other biomolecule structures. Said Core-1 mimicking structure is a structure which can be bound by at least one Core-1 specific antibody and/or can induce an immune response against Core-1, preferentially a humoral immune response against Core-1 or a cellular immune response against Core-1, and more preferentially a humoral immune response against Core-1 and a cellular immune response against Core-1.

[0024] In accordance with the present invention the term coreotic means a nutraceutical or nutraceutical formulation comprising at least one Core-1-positive microorganism or fraction thereof.

[0025] In accordance with the present invention the term "Core-1 positive disease" means any disease which is associated with a virus, microorganism, eukaryotic cell, tumor cell or other biological material which can be bound by at least one of the Core-1 specific antibodies or which is associated with a component of the body or occurring in the body of a human or animal such as but not limited to a cell, tumor cell, microorganism, virus or particle which is bound by at least one of the Core-1 specific antibodies.

[0026] A "therapeutic agent", as used herein, comprises at least one Core-1 positive microorganism or fraction thereof and can further comprise other components or elements or preferred a carrier of a pharmaceutical composition, drug and medicament known to those skilled in the art. Said carrier is a substance that may be associated with an active compound prior to administration to a human or a patient, generally for the purpose of controlling stability or bioavailability of the compound. Carriers for use within such formulations are generally biocompatible, and may also be biodegradable. Carriers include, for example, monovalent or multivalent molecules such as serum albumin (e.g., human or bovine), egg albumin, peptides, polylysine and poly-saccharides such as aminodextran and polyamidoamines. Carriers also include solid support materials such as beads and microparticles comprising, for example, polylactate polyglyco-late, poly(lactide-co-glycolide), polyacrylate, latex, starch, cellulose or dextran. A carrier may bear the compounds in a variety of ways, including covalent bonding either directly or via a linker group, noncovalent interaction or admixture.

[0027] The induction of an immune response against Core-1 as described elsewhere herein does also mean in sense of the invention the enhancement of an already existing immune response against Core-1.

BACKGROUND OF THE INVENTION

[0028] Aberrant glycosylation is a typical hallmark of cancer cells. The Core-1 antigen is masked by other carbohydrate components in healthy and benign-diseased tissue but uncovered in a majority of carcinomas and in some non-epithelial malignancies. Therefore, the core-1 antigen is a specific pancarcinoma antigen.

[0029] Core-1 is the disaccharide GalÅZÅ2 1-3 GalNAc, which is O-glycosidically linked in an AZA±-anomeric configuration to the hydroxy amino acids serine or threonine of proteins in carcinoma cells. Core-1 is expressed on over 60% of primary colon carcinomas and over 90% of liver metastases from colon cancer as well as on the majority of the carcinomas of other major indications including breast, lung, ovarian, prostate, and other gastrointestinal cancers such as gastric, and pancreatic carcinomas. Core-1 is an independent prognostic marker for patients with colon carcinomas, the mortality rate increases and the medium survival decreases in accordance with the increasing intensity of Core-1 expression. The development of liver metastases correlates with the expression of Core-1. Patients with Core-1 positive primary carcinomas develop liver metastases in nearly 60% of the cases, while the risk for liver metastasis with Core-1-negative tumours is significantly lower (less than 20%). Besides mediating metastasis into the liver Core-1 may also play a role in the metastasis via the endothelium.

[0030] The exceptionally high pan-carcinomic specificity, prognostic relevance and direct involvement in liver metastasis renders Core-1 a prime target for cancer immunotherapy. Due to the complexity and species specificity of the glycosylation machinery no immunotherapy based on Core-1 is available to cancer patients. Even more important, there is no agens available to patients which can prevent the development of Core-1 positive tumors. Conventional therapies usually start after tumor diagnosis , when tumors are often well established and difficult to treat. Therefore, aggressive therapies with severe side effects (chemotherapy, radiotherapy, surgery) are used to free the patients from tumor bulk. Immunotherapeutical options are mainly applied in the adjuvant setting with minimal residual disease.

[0031] On the contrary, the present invention focuses on preventing the development of Core-1 positive tumors by establishing an immunosurveillance mechanism that eliminates newly arising tumor cells, thereby preventing primary tumor growth. Conventional probiotics and prebiotics result in an overall unspecific stimulation of the immune system. There is no tumor-specific system involved. On the contrary, the present invention activates the immune system in a tumor-specific manner by inducing high anti-Core-1 antibody levels. To our knowledge, the present invention is the first antigen-specific food additive/ nutraceutical which is able to activate a specific immune shield against tumors and the first food-additive which is able to induce a carbohydrate tumor antigen-specific immune response. In addition, there is no systemic immune therapy against Core-1 positive tumors which comprises Core-1 positive microorgansims in a pharmaceutical composition nor methods available for providing such mircoorganisms.

[0032] The object of the present invention is to provide a technical teaching which would not involve the above mentioned drawbacks of the prior art, permitting easy, safe and efficient prophylaxis and treatment of Core-1 positive tumours and gastrointestinal disorders.

SUMMARY OF THE INVENTION

[0033] In a first aspect, the present invention provides a formulation selected from the group comprising a nutraceutical and/or a pharmaceutical composition, comprising at least one Core-1 positive microorganism selected from the group consisting of AG6 (DSM 18726) and Mill (DSM 18728), and/or at least one lysate or fraction thereof.

[0034] In a second aspect, the present invention provides a Core-1 positive microorganism selected from the group consisting of AG6 (DSM 18726) and Mill (DSM 18728), and/or a lysate or fraction thereof for use as a medicament and/or nutraceutical for therapy or prophylaxis of a tumor, or for in vivo or in vitro use in a method of inducing or enhancing a Core-1 specific immune response and/or for generating functional dendritic cells or activated T cells, T cell lines or T cell clones or antibodies against Core-1. In the following, AG6 and MUl are also referred to as the microorganism(s) or Core-1 positive microorganism(s) of or according to the invention.

[0035] In a third aspect, the present invention provides a bacterial strain selected from the group consisting of AG6 (DSM 18726) and MUl (DSM 18728), and/or a lysate or fraction thereof.

[0036] In a fourth aspect, the present invention provides a kit for inducing a specific humoral and/or cellular immune response in a human or animal against Core-1, the Core-1 antigen or Core-1 positive tumor cells, comprising a neutraceutical or pharmaceutical formulation comprising at least one Core-1 positive microorganism selected from the group consisting of AG6 (DSM 18726) and MUl (DSM 18728), and/or at least one lysate or fraction thereof, or comprising at least one Core-1 positive microorganism selected from the group consisting of AG6 (DSM 18726) and MUl (DSM 18728), or a fraction thereof, and an information about the use of the kit.

[0037] In a fifth aspect, the present invention provides a kit for reducing or preventing the occurrence of a core-1 positive disease or a tumor, comprising a neutraceutical or pharmaceutical formulation comprising at least one Core-1 positive microorganism selected from the group consisting of AG6 (DSM 18726) and MUl (DSM 18728), and/or at least one lysate or fraction thereof, or comprising at least one Core-1 positive microorganism selected from the group consisting of AG6 (DSM 18726) and MUl (DSM 18728), or a fraction thereof, and an information about the use of the kit.

[0038] The present invention provides the means for the induction or elevation of anti- Core-1 antibody levels in humans thereby inducing a protective immune response against tumors, especially Core-1 positive tumors. In addition, the invention provides for the first time the means for the induction of a specific cellular immune response against a carbohydrate target and especially against a tumor specific carbohydrate target. The present invention provides also for the first time the means for inducing a specific immune response and not a tolerance against a tumor target via oral administration. The invention also discloses for the first time methods for identification and isolation of suitable microorganism. Another advantage of the present invention is that due to the nature of the formulation the production causes very low costs. Furthermore, the formulation can be rapidly produced in large scale fermentors.

[0039] It was surprising that anti-Core-1 antibodies, induced by the formulation of the present invention, serve as an immunosurveillance mechanism which prevents the development of primary tumours and the distribution of metastases in most (unrecognised) cases, if the specific immune response is sufficiently high. Therefore, the aim of the invention is to provide the means to induce a high specific anti-Core-1 titre, preferably combined with a specific cellular response, by using Core-1 positive microorganisms firm the intestinal flora of healthy donors as food additives in order to build a specific immune shield against tumors or prevent or reduce the incidence of Core-1 positive tumours and/or their metastases.

[0040] Surprisingly, the provided microorganisms of the invention were capable of activating human T cells in a Core-1 specific manner when presented by human dendritic cells (in vitro). There are no reports documenting a cellular immune response and especially a cytotoxic cellular immune response against a carbohydrate tumor antigen and especially a small non-charged carbohydrate. There are no reports of presentation of human tumor carbohydrate antigens on human dendritic cells, the key regulators of the immune system, and especially not of human carbohydrate structures originating from microorganism. In contrast, the general scientific opinion is that humans do not develop a carbohydrate specific cellular immune response and especially not against carbohydrate tumor antigens. The microorganisms of this invention were processed and presented by human dendritic cells and those coreotic-loaded dendritic cells could be used to activate primary human T cells specifically against Core-1. Those T cells generated by sensitization with lysates from Core-1 positive bacteria of the present invention showed strong immune responses after restimulation with Core-1 positive human tumor cell lysates as documented by secretion of cytokines which document the specific T cell response and especially the cytotoxic T cell response.

[0041] It is surprising that it is possible to load human dendritic cells with Core-1 positive microorganism according to the present invention or with Core-1 carrying molecules and achieve a Core-1 specific activation of human T cells. It is even more surprising that immune cells activated by human dendritic cells loaded with said Core-1 positive microorganisms can be further activated or restimulated using human dendritic cells loaded with the Core-1 carrying molecules such as lysates from NM-D4 or NM-F9 or asialoglycophorin showing that (i) Core-1 specific T cells can be activated by Core-1 positive microorganism, and that (ii) this immune responses comprises Core-1 specific T cells which can be further activated or restimulated by DC loaded with Core-1 carrying molecules. It is further surprising that the Core-1 structure can be detected by Core-specific antibodies on DC loaded with Core-1 positive microorganism as well as on DC loaded with asialoglycophorin. It is further surprising that not only the secretion of GM-CSF and the proliferation of T-cells can be potently induced using Core-1 positive microorganism of the invention but also the secretion of INFgamma (interferon gamma) and even more surprising TNFalpha (tumor necrosis factor alpha) showing the activation of Core-1 specific cytotoxic T-cells. It is further surprising that the Core-1 specific T-cells can be restimulated for at least 4 times in vitro which indicates a strong and specific cellular immune response against the tumor antigen and tumor mediated by the T-cells. These immune responses are a proof to those skilled in the art that the Core-1 positive microorganisms provided by the present invention are able to induce a potent anti-Core-1 cellular immune response in humans.

[0042] Activation of cellular immunity in addition to humoral immunity strongly enhances the prophylactic and therapeutic potential of the microorganisms of the present invention. The usage of bacteria that usually inhabit the gastro-intestinal tract of humans results in a prophylactic and therapeutic agens that does not cause undesired side effects. The carbohydrate nature is responsible for the lack of relevant tolerogencity and shows no relevant allergic reactions.

[0043] Surprisingly, the formulation according to the present invention (e.g. food or drug comprising the Core-1 positive microorganism) can be used for prophylactic and therapeutic purposes and in supporting immunological activities. The pharmaceutical formulation of the invention contains Core-1 positive microorganism and a pharmaceutically acceptable carrier. The preparation and administration of formulation of this invention (e.g. drug comprising core-1 positive microorganism) is in accordance with known techniques. For example, the formulation can be combined with conventional galenic adjuvants to form a composition suitable for the desired method of application. For example, the compounds of this invention can be employed in mixture with conventional excipients, i.e., pharmaceutically acceptable organic or inorganic carrier substances suitable for parenteral or enteral application which do not deleteriously react with the active compounds. Suitable pharmaceutically acceptable carriers include but are not limited to water, salt solutions, alcohols, vegetable oils, polyethylene glycols, gelatin, lactose, amylose, magnesium stearate, viscous paraffin, perfume oil, fatty acid monoglycerides and diglycerides, pentaeyritol fatty acid esters, hydroxy methylcellulose, polyvinyl pyrrolidone, talc, etc. DESCRIPTION OF THE INVENTION: [0044] The invention provides nutraceuticals and pharmaceutical compositions comprising at least one Core-1 positive microorganism selected from the group consisting of AG6 and Mill or fractions thereof as well as Core-1 positive microorganism selected from the group consisting of AG6 and Mill and fractions thereof suitable to induce immune responses against Core-1 carrying tumor cells and Core-1 carrying molecules.

For example, a formulation intended for the oral administration of humans may vary from about 5 to about 95% of the total composition. Dosage unit forms will generally contain between from about 1 mg to about 10 g of active ingredient. It will be understood, however, that the specific dose level for any particular patient will depend upon a variety of factors including the activity of the specific compound employed, the age, body weight, general health, sex, diet time of administration, route of administration, rate of excretion, drug combination and the severity of the particular disease undergoing therapy. The dosage effective amount of compounds according to the invention will vary depending upon factors including the particular compound, toxicity, and inhibitory activity, the condition treated, and whether the compound is administered alone or with other therapies. Typically a dosage effective amount will range from about 0.0001 mg/kg to 1500 mg/kg, more preferably 1 to 1000 mg/kg, more preferably from about I to 150 mg/kg of body weight, and most preferably about 50 to 100 mg/kg of body weight. The invention relates also to a process or a method for the treatment of the abovementioned pathological conditions. The compounds of the present invention can be administered prophylactically or therapeutically, preferably in an amount that is effective against the mentioned disorders, to a warm-blooded animal, for example a human, requiring such treatment, the compounds are preferably being used in the form of pharmaceutical compositions or nutraceuticals.

[0179] Formulation of pharmaceutically-acceptable excipients and carrier Solutions is well-known to those of skill in the art, as is the development of suitable dosing and treatment regimens for using the particular compositions described herein in a variety of treatment regimens, including e.g., oral, parenteral, intravenous, intranasal, and intra-muscular administration and formulation. A. Oral Delivery [0180] In certain applications, the formulations disclosed herein may be delivered via oral administration to a human or an animal. As such, these compositions may be formulated with an inert diluent or with an assimilable edible carrier, or they may be enclosed in hard- or soft-shell gelatin capsule, or they may be compressed into tablets, or they may be incorporated directly with the food of the diet.

[0181] The active compounds may even be incorporated with excipients and used in the form of ingestible tablets, buccal tables, troches, capsules, elixirs, suspensions, syrups, wafers, and the like. The tablets, troches, pills, capsules and the like may also contain the following: a binder, as gum tragacanth, acacia, cornstarch, or gelatin; excipients, such as dicalcium phosphate; a disintegrating agent, such as corn starch, potato starch, alginic acid and the like; a lubricant, such as magnesium stearate; and a sweetening agent, such as sucrose, lactose or Saccharin may be added or a flavoring agent, such as peppermint, oil of wintergreen, or cherry flavoring. When the dosage unit form is a capsule, it may contain, in addition to materials of the above type, a liquid carrier. Various other materials may be present as coatings or to otherwise modify the physical form of the dosage unit. For instance, tablets, pills, or capsules may be coated with shellac, sugar, or both. A syrup of elixir may contain the active compound sucrose as a sweetening agent methyl and propylparabens as preservatives, a dye and flavoring, such as cherry or orange flavor. Of course, any material used in preparing any dosage unit form should be pharmaceutically pure and substantially non-toxic in the amounts employed. In addition, the active compounds may be incorporated into sustained-release preparation and formulations.

[0182] Typically, these formulations may contain at least about 0.1 % of the active compound or more, although the percentage of the active ingredient (s) may, of course, be varied and may conveniently be between about 1 or 2% and about 60% or 70% or more of the weight or volume of the total formulation. Naturally, the amount of active compound(s) in each therapeutically useful composition may be prepared is such a way that a suitable dosage will be obtained in any given unit dose of the compound. Factors such as solubility, bioavailability, biological half-life, route of administration, product shelf life, as well as other pharmacological considerations will be contemplated by one skilled in the art of preparing such pharmaceutical formulations, and as such, a variety of dosages and treatment regimens may be desirable.

[0183] For oral administration the compositions of the present invention may alternatively be incorporated with one or more excipients in the form of a mouthwash, dentifrice, buccal tablet, oral spray, or sublingual orally-administered formulation. For example, a mouthwash may be prepared incorporating the active ingredient in the required amount in an appropriate solvent, such as a sodium borate solution (Dobell's Solution). Alternatively, the active ingredient may be incorporated into an oral solution such as one containing sodium borate, glycerin and potassium bicarbonate, or dispersed in a dentifrice, or added in a therapeutically-effective amount/ effective dose to a composition that may include water, binders, abrasives, flavoring agents, foaming agents, and humectants. Alternatively the compositions may be fashioned into a tablet or solution form that may be placed under the tongue or otherwise dissolved in the mouth. B. Injectable Delivery [0184] In certain circumstances it will be desirable to deliver the formulations disclosed herein parenterally, intravenously, intramuscularly, or even intraperitoneally. Solutions of the active compounds as free base or pharmacologically acceptable salts may be prepared in water suitably mixed with a surfactant, such as hydroxypropylcellulose. Dispersions may also be prepared in glycerol, liquid polyethylene glycols, and mixtures thereof and in oils. Under ordinary conditions of storage and use, these preparations contain a preservative to prevent the growth of microorganisms.

[0185] The pharmaceutical forms suitable for injectable use include sterile aqueous solutions or dispersions and sterile powders for the extemporaneous preparation of sterile injectable solutions or dispersions. In all cases the form must be sterile and must be fluid to the extent that easy syringability exists. It must be stable under the conditions of manufacture and storage and must be preserved against the contaminating action of microorganisms, such as bacteria and fungi. The carrier can be a solvent or dispersion medium containing, for example, water, ethanol, polyol (e.g., glycerol, propylene glycol, and liquid polyethylene glycol, and the like), suitable mixtures thereof, and/or vegetable oils. Proper fluidity may be maintained, for example, by the use of a coating, such as lecithin, by the maintenance of the required particle size in the case of dispersion and by the use of surfactants. The prevention of the action of microorganisms can be facilitated by various antibacterial and antifungal agents, for example, parabens, chlorobutanol, phenol, sorbic acid, thimerosal, and the like. In many cases, it will be preferable .to include isotonic agents, for example, sugars or sodium Chloride. Prolonged absorption of the injectable compositions can be brought about by the use in the compositions of agents delaying absorption, for example, aluminum monostearate and gelatin.

[0186] For parenteral administration in an aqueous solution, for example, the solution should be suitably buffered if necessary and the liquid diluent first rendered isotonic with sufficient saline or glucose. These particular aqueous Solutions are especially suitable for intravenous, intramuscular, subcutaneous and intraperitoneal administration. In this connection, a sterile aqueous medium that can be employed will be known to those of skill in the art in light of the present disclosure. For example, one dosage may be dissolved in 1 ml of isotonic NaCI solution and either added to 1000 ml of hypodermodysis fluid or injected at the proposed site of infusion. Some Variation in dosage will necessarily occur depending on the condition of the subject being treated. The person responsible for administration will, in any event, determine the appropriate dose for the individual subject. Moreover, for human administration, preparations should meet sterility, pyrogenicity, and the general safety and purity Standards as required by national or regional Offices of biologies Standards.

[0187] Sterile injectable Solutions are prepared by incorporating the active compounds in the required amount in the appropriate solvent with various of the other ingredients enumerated above, as required, followed by filtered sterilization. Generally, dispersions are prepared by incorporating the various sterilized active ingredients into a sterile vehicle which contains the basic dispersion medium and the required other, ingredients from those enumerated above. In the case of sterile powders for the preparation of sterile injectable Solutions, the preferred methods of preparation are vacuum-drying and freeze-drying techniques which yield a powder of the active ingredient plus any additional desired ingredient from a previously sterile-filtered solution thereof.

[0188] The compositions disclosed herein may be formulated in a neutral or salt form. Pharmaceutically-acceptable salts, include the acid addition salts (formed with the free amino groups of the protein) and which are formed with inorganic acids such as, for example, hydrochloric or phosphoric acids, or such organic acids as acetic, oxalic, tartaric, mandelic, and the like. Salts formed with the free carboxyl groups can also be derived from inorganic bases such as, for example, sodium, potassium, ammonium, calcium, or ferric hydroxides, and such organic bases as isopropylamine, trimethylamine, histidine, procaine and the like. Upon formulation, Solutions will be administered in a manner compatible with the dosage formulation and in such amount as is therapeutically effective. The formulations are easily administered in a variety of dosage forms such as injectable Solutions, drug-release capsules, and the like.

[0189] As used herein, "carrier" includes any and all solvents, dispersion media, vehicles, coatings, diluents, antibacterial and antifingal agents, isotonic and absorption delaying agents, buffers, carrier Solutions, suspensions, colloids, and the like. The use of such media and agents for pharmaceutical active substances is well known in the art. Except insofar as any conventional media or agent is incompatible with the active ingredient, its use in the therapeutic compositions is contemplated. Supplementary active ingredients can also be incorporated into the compositions.

[0190] The phrase "pharmaceutically-acceptable" refers to molecular entities and compositions that do not produce an allergic or similar untoward reaction when administered to a human. The preparation of an aqueous composition that contains a protein as an active ingredient is well understood in the art. Typically, such compositions are prepared as injectables, either as liquid Solutions or suspensions; solid forms suitable for solution in, or Suspension in, liquid prior to injection can also be prepared. The preparation can also be emulsified.

[0191] In a preferred embodiment of the invention the nutraceutical or formulations thereof comprising at least one Core-1 positive microorganism or fraction thereof are applied to humans as a food additive. In a preferred embodiment of the invention the nutraceutical or formulations thereof comprising at least one Core-1 positive microorganism or fraction thereof are applied to humans as a medical food.

[0192] The invention relates also to the nutraceutical or a formulation thereof which comprise at least one Core-1 positive microorganism or fraction thereof according to the invention as a food-additive or as food or as a component thereof. Food in the context of invention is any substance consumed by living organisms, including liquid drinks. Food is the main source of energy and of nutrition for animals/humans, and is usually of animal or plant origin. The food is preferred vegan food which is generally all types of food that are free of animal products, like meat, milk or eggs. The food in the context of the invention is also preferred non-vegan food containing animal products. Food in the context of the invention is: (i) any substance or product, whether processed, partially processed or unprocessed, intended to be, or reasonably expected to be ingested by humans whether of nutritional value or not; (ii) water and other drinks; (iii) chewing gum or candy products; and/or (iv) articles and substances used as an ingredient or component in the preparation of food. Food in the context of the invention is traditionally obtained through farming, ranching, and fishing, with hunting, foraging and other methods of subsistence locally important for some populations, but minor for others. In the modern era, in developed nations, food supply is increasingly dependent upon agriculture, industrial farming, aquaculture and fish farming techniques which aim to maximise the amount of food produced, whilst minimising the cost. These include a reliance on mechanised tools which have been developed, from the threshing machine, seed drill, through to the tractor and combine, etc. These have been combined with the use of pesticides to promote high crop yields and combat those insects or mammals which reduce yield. More recently, there has been a growing trend towards more sustainable agricultural practices. This approach - which is partly fuelled by consumer demand - encourages biodiversity, local self-reliance and organic farming methods.

[0204] In a study with healthy human volunteers serum antibody titers against Core-1 are determined by determining the existing antibody response against Core-1 before first application of the nutraceutical and preferably volunteers with no or lower anti-Core-1 antibody levels are selected for the human trial. In those volunteers the nutraceutical comprising AG6 or MU1 or a placebo are orally given over a period of 3 to 30 weeks. Oral application of at least two different dosages is performed. Immune responses are followed by determination of the antibody and/or T cell response against Core-1 prior to and in suitably intervals after start of oral administration of the nutraceutical. There is a significant elevation of the antibody response against Core-1 and/or T cell response against Core-1 observed in a significant number of volunteers in the volunteer group that receives the nutraceutical in comparison to the titer before the study as positively tested by being positive. In the placebo group elevation of antibody or T-cell response against Core-1 is less frequently observed or to a lesser extend. This shows the effectiveness of the nutraceutical in humans for building an immune response against Core-1 which functions as a shield against Core-1 positive cancer cells for the prevention, reduction or spread of Core-1 positive tumors or metastasis or its treatment.

[0205] In a study with human immuno competent cancer patients with Core-1 positive tumors serum antibody titers against Core-1 are determined by determining the existing antibody response against Core-1 before first application of the pharmaceutical composition. The pharmaceutical composition comprising AG6 or MU1 or a placebo are administered several times orally, intra peritoneally or intra venously over a period of 3 to 70 weeks. Administration of at least two different suitable dosages is performed. Immune responses are followed by determination of the antibody and/or T cell response against Core-1 and /or the clinical response are followed by determination of time to progression, tumor free survival and/or tumor volumes and/or sites, each prior to and in suitably intervals after start of the administration of the pharmeutical composition.

EXAMPLES

Example 1 Anaerobic culture techniques and media [0276] Anaerobic techniques employed in the cultivation of bacteria were based on methods previously described (3, 5, 9, 11), which have been summarised by Breznak and Costilow (4). Media prepared with cysteine-HCI as a reducing agent were dispensed into anaerobic culture tubes (Ochs, Bovenden, Germany) or glass serum bottles, leaving approximately half to a third of the total vessel volume as gas head space, and sealed with butyl rubber stoppers. Solutions prepared without reducing agents (e.g. PBS-a) were boiled prior to dispensing. Before autoclaving, the gas phase was replaced with N2/CO2 (80/20,v/v). To achieve this, needles were thrust through the butyl rubber-stoppered bottles and the bottles were evacuated by means of a vacuum pump (Vacuubrand, Wertheim, Germany). Following evacuation, bottles, which were repeatedly shaken during the entire process, were gassed with N2/CO2 (80/20,v/v). This evacuation and gassing procedure was carried out three times in total. Prior to entering the vessels, the gas mixture was passed over a hot palladium catalyst to remove residual traces of oxygen present in the gas mixture. Resazurin (1 mg 11) was used as a redox indicator.

[0277] Media for plating were poured under a laminar flow hood and stored under anoxic conditions for at least 24 h before use. This was achieved in either pressurised (1.5xl03 Pa) anaerobic jars with a 3.5 1 AnaeroGen (Oxoid, Basingstoke, England) or with a repeatedly flushed N2/CO2/H2 (80/10/10, v/v/v) anaerobic chamber airlock (Don Whitley Scientific, Shipley, England). Manipulation of samples was carried out in an anaerobic chamber (MACS variable atmosphere workstation, Don Whitley Scientific, Shipley, England or Coy Laboratory Products, Grass Lake, USA).

[0278] Non-sterile solutions and materials were sterilised by autoclaving (121 C, 1.2 x 105 Pa, 15 min). Heat-labile compounds were made as concentrated stock solutions in milli-Q water, sterile-filtered (0.22 pm, mixed cellulose ester, Roth, Karlsruhe, Germany) and added to media at the concentrations required.

Example 2: Affinity enrichment of core-1 positive microorganisms 2.1 Preparation of TF1 and TF2 coated Dynabeads®

[0279] A volume of 100 pi Dynabeads® (M-450 Rat Anti-Mouse IgM, Dynal Biotech ASA, Oslo, Norway) each was placed in 2 ml Safe-Lock Eppendorf tubes (Eppendorf, Hamburg, Germany), washed twice with 2 ml phosphate buffered saline a (PBS-a: 8.1 g r1 NaCI, 0.16 g l'1 NaH2P04-H20, 0.98 g 1 1 Na2HP04-2H20, 1 g l'1 BSA, pH 7.4) using the Dynal Magnetic Particle Concentrator®-S (MPC®-S, Dynal Biotech, Oslo, Norway) and suspended in 25 pi of PBS-a. Lyophilised TF1 or TF2 cell culture supernatants were dissolved in 1 ml milli-Q synthesis grade water (Millipore, Billerica, MA, USA). Dissolved TF1 or TF2 cell culture supernatant (1 ml) were added to the tubes with Dynabeads® and incubated for 30 min at 4 C on a test tube rotator (model 34528, Snijders Scientific, Netherlands). Tubes were placed in the MPC®-S and left to stand for 3 min before removing the fluid with a pipette. The Dynabeads® were re-suspended in 2 ml PBS-a, placed in the MPC®-S and the fluid removed by pipetting. This washing step was performed three times. Washed Dynabeads® were suspended in their original volume of 100 pi PBS-a. Dynabeade prepared in this manner were either used immediately or within two weeks of preparation after a repeated three-fold wash step with 2 ml PBS-a. 2.2 Collection and processing of faecal samples for Dynabeads® enrichment [0280] Faecal samples of eight volunteers (Table 3) were collected in perforated plastic tubes, maintained under anoxic conditions using an AnaeroGen Compact (Oxoid, Basingstoke, England) and stored at 4 C for a maximum of 4 h before processing. Volunteers were healthy adults who had not taken antibiotics for at least 3 months prior to the sampling date and consumed their usual diets.

Table 3: Individual parameters at the time of faecal sample collections

[0281] A tenfold (w/v) dilution of the faecal samples was prepared in PBS-b (PBS-b: 8.5 g I"1 NaCI, 0.3 g 11 KH2PO4, 0.6 g I 1 Na2HP04, pH 7.0 containing 0.1 g I"1 peptone and 0.25 g I"1 cysteine-HCI). Six sterile 3 mm diameter glass beads were added and the diluted samples were homogenised by low speed vortexing. The homogenised sample was centrifuged (300 x g, 1 min, 21 C) to sediment debris. A 200 pi portion of the resulting supernatant was added to 1.8 ml PBS-b resulting in an approximately 100-fold dilution of the original faecal sample. These dilutions were washed once with 2 ml PBS-b (8000 x g, 5 min, 21 C) and the pellets suspended in 2 ml PBS-b. 2.3 Dynabeads® enrichment procedure [0282] A volume of 20 μΙ from the 100-food dilution was added to a 2 ml tube containing 180 μΙ of PBS-a and 5 μΙ of either TF1 or TF2 antibody coated Dynabeads®. The tubes were incubated for 30 min at 4 C on a test tube rotator. Tubes were placed in the MPC ®-S and left to stand for 3 min before removing as much of the supernatant as possible by aspiration with a syringe and needle. The samples were washed three times with 2 ml PBS-a, again removing as much of the supernatant as possible. 2.4 Plating on selective and non-selective media [0283] Washed samples were suspended in 1 ml PBS-b and 100 μΙ aliquots were spread-plated on various selective and non-selective media (Table 4) and incubated for 48h at 37°C in an anaerobic chamber.

Table 4: Media employed for spread-plating

[0284] Solid media were prepared according to the manufacturers' instructions. The composition of ST agar was as follows: 1 g I"1 proteose peptone, 9 g I"1 peptone from meat, 3 g I"1 NaCI, 2 g 11 Na2HP04-2H20, 3 g I 1 meat extract, 4 g I"1 yeast extract, 6 g I"1 D (+)-glucose, 0.5 ml l"1 Tween 80, 0.25 g I 1 cysteine-HCI, 1 mg 11 resazurin, 0.1 g I"1 MgSC>4-7 H20, 5 mg I"1 FeS04·7 H20, 0.5 g I"1, 3.4 mg I"1 MnS04-2H20, 1.5 g 11 bacteriological agar, pH 7.0.

[0285] For subjects 1 to 4, colonies from one enrichment procedure were selected for ELISA-based screening. For subjects 5 to 8, the Dynabeads® enrichment procedure was repeated twice as follows: Following 48 h incubation, colonies were scraped from the plates, suspended in PBS-b within the range of McFarland turbidity standards 3 to 5 (prepared as in (13)). As before, a 20 pi aliquot of this suspension was added to 180 μΙ of PBS-a. The enrichment and plating procedure was performed three times in total, as previously described.

[0286] The faecal samples of a further four subjects (5 AB, 6 MU, 7 LH and 8 CA) were enriched for Core 1 positive bacteria. The enrichment procedure was modified slightly in that the enrichment was carried out three times in total. I.e. colonies obtained after the initial isolation were scraped from the plates and subjected to a further enrichment. Sixty new isolates were obtained in this manner. 3 Identifcation of isolates 3.1 Biochemical [0287] Bacteria were identified with the VITEK system (Biomérieux, Marcy I'Etoile, France). Bacteria were prepared according to the manufacturer's instructions and the identification cards used were as follows: ANI cards for anaerobic isolates and faculatively anaerobic Gram-positive rods able to grow in MRS broth (suspected lactobacilli), GPI cards for Gram-positive isolates and GNI+ cards for Gram negative aerobic isolates.

[0288] The biochemical identity of the isolates obtained using the VITEK system (Biomérieux, Marcy I'Etoile, France) is summarised in Table 5. The anaerobic isolates AG6, MU (1, 3-5) and AB12 all belong to the Bacteroides fragilis group, whereas the aerobic isolates are all members of the Enterobacteriaceae; both are Gram-negative. Table 5: Identification of the Isolated strains based upon biochemical characteristics (VITEK)

3.2 Molecular (Sequencing) [0289] DNA was extracted with the Invisorb Genomic DNA Kit III (Invitek, Berlin, Germany) following manufacturer's instructions for protocol III B with washed cell pellets obtained from liquid cultures suspended in 1 ml of lysis buffer D. Primers 27f (5' AGA GTT TGA TCC TGG CTC AG) and 1492r (5' TAC CTT GTT ACG ACT T) (10) were used to amplify the bacterial 16S ribosomal RNA gene.

[0290] Each PCR was performed in triplicate and the reaction mixture (50 pi) contained: 50 mM KCI, 20 mM Tris-HCI, 1 mM MgCl2, 0.25 mM each dNTP, 1 μΜ each primer, 2.5 units Taq DNA polymerase (Invitrogen, Karlsruhe, Germany) and 1 pi of the template DNA. The PCR program was: 94°C for 5 min, 30 cycles of 94°C for 1 min, 55°C for 1 min and 72°C for 1 min, and finally 72°C for 10 min. PCR products were purified with the High Pure PCR Product Purification Kit (Roche, Indianapolis, USA) following manufacturer's instructions. The products were analyzed by electrophoresis on a 1 % agarose gel (w/v) in Tris-Acetate-EDTA buffer (4.84 g Γ1 Tris, 1.142 ml l"1 glacial acetic acid 0.372 g 1 1 EDTA, pH 8.0). The DNA concentration was estimated using the Low DNA Mass Ladder (Invitrogen, Carlsbad, USA).

[0291] For sequencing, we used either primer 27f, 338f (5' GCT GCC TCC CGT AGG AGT) (2), 338r (5’ ACT CCT ACG GGA GGC AGC), 968f (5' AAC GCG AAG AAC CTT AC) (14), or 1492r. Sequencing reactions were performed with the DYEnamic™ ET Dye Terminator Cycle Sequencing Kit (Amersham Biosciences, Little Chalfont, England) following manufacturer's instructions. Sequencing products were analyzed with the MegaBACE 1000 System (Molecular Dynamics, Sunnyvale, USA). Sequences were assembled and manually adjusted using the ContigExpress function of the Vector NTI Suite 9.0.0 (Invitrogen, Carlsbad, USA). They were subsequently aligned with highly similar sequences (92% similarity or more) obtained with the BLAST function of the National Center for Biotechnology Information (NCBI) (1). Percentages of similarity were calculated from unambiguously aligned sequences using the Sequence Identity Matrix function of the Bioedit software version 5.0.9 or the Similarity Matrix version 1.1 of the Ribosomal Database Project. Sequencing results were confirmed by comparison with sequences obtained from a 16S rRNA gene sequencing service provider (AMODIA, Braunschweig, Germany).

[0292] The identity of the isolates is depicted in Table 6 and an unrooted phylogenetic tree based on the sequences of the isolates AG6, MU1, their closest relatives and the E. coli ATCC 11755 type strain is depicted in Fig. 1.

I 3.3 Random Amplified Polymorphic DNA (RAPD) [0293] Some Core 1 positive isolates obtained with the repeated Dynabead® enrichment procedure appeared very similar in their cell and colony morphology, despite having being isolated from different media. The strains were also very similar with regard to their biochemical profiles obtained with the VITEK system. The question arose, whether the isolated bacteria are identical strains. RAPD is a method that does not require sequence information, which can be applied to distinguish strains. Briefly, total genomic DNA is PCR amplified with a 10 base pair primer at low stringency so that random sequences of DNA are amplified based on homologous sequences to the primer being present in the target DNA. The resulting PCR products can be separated by agarose gel electrophoresis and the resulting pattern can be compared between strains. The resulting band patterns for all LH strains were analogous for the five RAPD primers (OPL07, M13, 0PX14, OPA16, OPA18) employed. The pattern clearly differs from that of E. coli strain DSMZ 8697 (Fig. 2a), a strain that has been reported to have blood group B activity. The MU strains also appear very similar (Fig. 2b); however their band pattern clearly differs from that of other Bacteroides strains, including AG6. It would appear that one Core 1 positive strain was repeatedly enriched from each positive donor during the isolation process. The strains isolated differed between individuals.

Example 4 Growth and fixation of bacteria for the ELISA-based screening [0294] Well separated colonies were randomly picked from selective and non-selective agar plates and restreaked three times on non-selective media. Single colonies were picked and inoculated into ST (as above, omitting the agar), WC or MRS broth, depending on which afforded best growth, and grown overnight at 37°C. These cultures were inoculated (1 %) into 300 ml fresh ST, WC or MRS broth and grown overnight at 37°C. Cells were pelleted (8000 x g, 15 min, 4 C) and re-suspended in 10 ml PBS-c (8 g Γ1 NaCI, 0.2 g Γ1 KCI, 1.44 g Γ1 Na2HPC>4, 0.24 g 1 1 KH2PO4) (12). This suspension was fixed 3 for to 4 h at 4 C by the addition of 30 ml of 4 % paraformaldehyde (PFA) solution (prepared according to (8)) in PBS-c. Next, samples were washed with 40 ml PBS-c (8000 x g, 15 min, 4 C) and the pellets suspended in 15 ml PBS-c, followed by addition of an equal volume of 96 % ice-cold ethanol. Samples were stored at -20 C until analysis.

[0295] The purity of cultures was checked by comparing cell morphology, as well as Gram staining behaviour. Cultures were plated aerobically on CBA to determine their ability to grow in the presence of oxygen and to check for the absence of aerobic contaminants.

Example 5 Maintenance of isolates [0296] Cryo-stocks were maintained in Microbank tubes (MAST Diagnostica, Reinfeld, Germany) according to the manufacturer's instructions and stored at -80 °C. Working stocks were maintained in WC, ST or MRS broth. These were sub-cultured every 14 days. The purity of the cultures was ascertained by observation of Gram-staining behaviour, cell morphology and periodic comparison of colony morphologies on CBA streak plates under both aerobic and anaerobic conditions.

Example 6 Growth, fixation and lyophilisation of bacteria for animal experiments [0297] For use in animal experiments the bacteria were grown and fixed as described in section 3 with the following modifications: The initial culture volume amounted to approximately 4 1. Before fixation, bacteria were washed once with 100 ml PBS-b (8000 x g, 15 min, 4 C) and re-suspended in the minimal possible volume of PBS-b. This suspension was split into two equal portions, one for fixation (7.1), the other for lyophilisation (7.2). 6.1 Fixation [0298] The portion for fixation was washed (8000 x g, 15 min, 4 C) and re-suspended in 30 ml PBS-c. This suspension was added to 90 ml of the 4 % PFA solution in PBS-c and fixed for 3 to 4 h at 4 C. To improve the removal of PFA, samples were washed three times with 120 ml PBS-c (8000 xg, 15 min, 4 C). Cell pellets were suspended in 45 ml PBS-c, followed by addition of an equal volume of 96 % ice-cold ethanol. Samples were stored at -20 °C. Before administration to the animals, fixed bacteria were lyophilised under sterile conditions in Lideac tubes (Eppendorf, Hamburg, Germany) to evaporate the ethanol. To ensure non-viability of the fixed bacteria, they were inoculated (1 %) into WC broth and plated on CBA and monitored for absence of growth for the period of one week. 6.2 Pasteurization [0299] Bacterial suspensions were washed twice in PBS and resuspended in a small volume of PBS. Bacterial suspension were incubated at 72°C for 30min. As a control for successful inactivation bacteria were incubated in a suitable culture medium as described in example 4. 6.3 Lyophiiisation [0300] The portion for lyophiiisation was added to an equal volume of 24 % sterile-filtered sucrose and aliquoted in 300 pi portions into 2 ml LidBac tubes. These aliquots were snap-frozen in liquid nitrogen for 1 h and lyophilized (Alpha 2-4, Christ, Osterode, Germany) after placing them into racks pre-cooled to -80 °C. Following lyophiiisation, the lids of the tubes were closed and they were stored at 4 °C using the Anaerocult® C mini gas generator system (Merck, Darmstadt, Germany) with the addition of silica gel orange (Roth, Karlsruhe, Germany) as a desiccant. 6.4 Enumeration of bacteria preparations [0301] Total cell numbers of fixed and lyophilised bacteria preparations were determined with a 0.41 mm depth Thoma-chamber (LO-Laboroptik, Friedrichsdorf, Germany). For lyophilised bacteria, the colony-forming units (CFU) were determined by plating 10-fold serial dilutions on WC agar of the overnight cultures and immediately before and after lyophiiisation. For this purpose, the lyophilate was dissolved in 300 μΙ WC broth, left to stand for 15 min, re-suspended by low speed vortexing and serially diluted. The CFU of lyophilised preparations were enumerated before and after use in animal experiments to ensure viability. The purity of the preparations was checked as described in section 4.

Example 7 Serum samples [0302] Blood was collected with the S-monvette system (Sarstedt, Numbrecht, Germany) and serum was prepared according to the manufacturer's instructions. Serum samples were stored in aliquots at -80°C prior to analysis.

Example 8 Faecal IgA Extraction [0303] Faecal samples were collected, stored at -80 °C. Faeces were lyophilised and net dry weights recorded. All manipulations were carried out on ice. Faecal IgA was extracted according to Grewal (6) with some modifications. Lyophilised samples (~30 mg) were suspended at a ratio of 15 μΙ/mg dry weight in IgA extraction buffer (PBS-Dulbecco (Biochrom, Berlin, Germany) with 1 g I"1 BSA) with protease inhibitors (5 pg ml"1 leupeptin (Calbiochem, Merck), 48 pg ml1 4-(2-aminoethyl)benzenesulfonylfluoride (Merck), 1 pg ml'1 aprotinin, 2 pg ml1 bestatin (Sigma, Steinheim, Germany) and homogenised. The samples were mixed by vortexing every 10 min. Following a 1 h incubation period, the samples were centrifuged (16000 x g, 10 min, 4 °C) and the supernatant was collected in a new tube. The remaining pellet was suspended at a ratio of 10 μΙ/mg dry weight in IgA extraction buffer and homogenised. The extraction procedure was repeated and the resulting supernatant combined with the supernatant from the first extraction step. These supernatants were centrifuged (16000 x g, 10 min, 4 °C) and the resulting supernatant was dispensed into new tubes, snap-frozen in liquid nitrogen and stored at -80 °C until analysis.

Example 9 Screening of bacterial strains by enzym-linked immunosorbent assay [0304] Fixed bacteria were diluted in PBS,cell numbers were adjusted to lxlO3, lxlO6, 5x 106, lxlO7, lxlO8 or 5xl08cells/ml. 50 μΙ of bacterial solution were coated per well of a 96 well microtiterplate over night at 37°C. Plates were washed 3 times with PBS/ 0,02 % Tween 20 (Identical washing steps were performed after each incubation step.)· After blocking of plates with PBS/2% BSA, ELISA plates were incubated with hybridoma culture supernatants containing different Core-1 recognizing monoclonal antibodies (Nemod-TFl, Nemod-TF2 or A68/BA11,) or control antibody (A63-B/C2) in different dilutions. As secondary antibody served a peroxidase-conjugated polyclonal goat-anti-mouse immunoglobulin (Dako P0260). The assay was developed with TMB as substrate, reaction was stopped by addition of 2.5 N H2SO4 and extinction was measured at 450 / 630 nm. For determination of periodate sensitivity of the antibody binding, coated ELISA plated were incubated with sodium periodate prior to the incubation with antibodies. Therefore, plates were washed with sodium acetate buffer (50mM, pH 4,5) for 5 min and afterwards incubated with lOmM periodic acid in sodium acetate buffer for lh in the dark. Plates were washed with sodium acetate buffer (5min) and the reaction was stopped by addition of 50mM sodium borohydrid in PBS (30min).

[0305] An example of such ELISA results is shown in figure 3.

Example 10: Preparation of Core-l-containing components of bacteria 10.1. Analysis of crude capsule preparations by SDS-PAGE and Western blot analyses [0306] Crude capsule preparations of strain AG6 were performed according to Pantosti et al. (1991, Infect. Immun. 59, 2075-2082).

[0307] Capsule preparation was analysed by SDS-PAGE and polysaccharide in the preparation were detected by alcian blue staining after Karlyshev et al. (2001, J. Clin. Microbiol. 39, 279-284) showing a variety of carbohydrate containing bands and high percentage of high molecular weight carbohydrates within the preparation (fig. 4A). After Western blot, polysaccharides were detected by the DIG-Glycan Detection Kit (LaRoche Diagnostics). Showing strong bands at 37 and 26 kDa. (fig. 4B). Detection of core-l-containing polysaccharige on the western blot was performed using the core-1-specific antibody NEMOD-TF2 (culture supernatant) showing a core-1-positive band at 37kDa (fig. 4C). 10.2. Chromatographic enrichment of core-1 positive polysaccharides [0308] Within the capsule preparation of strain AG6 there were still contaminants of lipopolysaccharides as shown by the measurement od KDO content of ll,2pmol/pg after Haraet al. 1989, Anal. Biochem. 179, 162-166) and by SDS-PAGE.

[0309] Therefore capsule polysaccharides and lipopolysaccharides were separated by reversed phase chromatography on a C18 column using a propanol/methanol-gradient (see fig. 5) according to Hashimoto et al. (2001, Eur. J. Biochem. 268, 3139-3144). Polysaccharides were eluted by a gradient of eluent B (72% propanol/ 8% methanol in 0,1M ammonium acetate pH 4.5). Detection of polysaccharides within the fractions was perform by dot blot and DIG-Glycan-Kit. Detection of core-1 was performed using the core-1 specific antibodies Nemod-TFl and Nemod-TF2. Polysaccharides were eluted at propanol concentrations of 14-19% and 25-43%. Core-1 specific carbohydrate were only detected at 29-29,4% propanol (RP1) and 39-42% propanol (RP2), see fig. 5 showing strong enrichment of core-1 positive polysaccharide by this method.

[0310] Core-1 positive fractions were used for additional chromatographic separations by mild acid hydrolysis followed by DEAE-chromatography using a 0-0.5M NaCI gradient according to Tzianabos et al. (1992, J. Biol. Chem. 267, 18230-18235). By this method the Core-1-positive polysaccharides were separated into three fractions eluted at 0 M NaCI (Dl), 0,04 M NaCI (D2) and 0,9-0,17 M NaCI (D3), resulting in a further enrichment of core-1-positive polysaccharides.

[0311] Capsular polysaccharides of B. ovatus AG6 are purified and the structure is analysed by mass spectrometry. Preferable, the capsular polysaccharidee of B. ovatus AG6 are accumulated by the phenol water extraction followed by ether extraction as already described by Pantosti et al. 1991. Thereafter, the core-1-positive polysaccharide is accumulated from rough capsular preparation (CPS) by reverse phase chromatography (C18 Synergi 4μ Fusion-RP 80i, 250 mm x 10mm, Phenomenex). The monosaccharide contents of rough capsular polysaccharide extract and purified core-1-positive polysaccharide are determined by HPAEC-PAD analyses (high pH anion exchange chromatography, pulsed amperometric detection). Finally the structure of the core-1-positive capsular polysaccharide is analysed by mass spectrometry. 10.3Monosaccharide analyses of rough capsular preparation extract and purified capsular extract of B. ovatus AG6 [0312] In the first step, the core-1-positive polysasccharide of the rough capsular preparation of B. ovatus AG6 was accumulated by reverse phase chromatography as already described before. Thereafter, the yield of purification as well as the monosaccharide content of accumulated core-1-positive polysasccharide was determined by HPAEC-PAD analyses.

[0313] Before monosaccharide analyses occurred, polysaccharide extracts was completely hydrolysed by 2 N trifluoroacetic acid (TFA) at 100 °C for 4 h. During the TFA hydrolyses the acetyl groups were lost. Therefore the monosaccharides glucosamin and galactosamin (GlcNH2 and GalNH2) could not distinguish from N-acetylglucosamin and /V-acetylgalactosamin (GIcNAc and GalNAc). Monosaccharides were separated by high pH anion exchange chromatography and detected by pulsed amperometry as already described before. To identify the monosaccharides and to determine their concentrations, external and internal monosaccharide standards were used.

[0314] The proportional monosaccharide content of rough CPS extract, which was determined for LPS and CPS comparision (mentioned before), obviously vary from the proportional monsaccharide content of rough CPS extract determined for this comparision. Both rough CPS extracts were prepared from different cultures of B. ovatus AG6, which might be an explication for the mentioned variety of monosaccharide contents.

[0315] The yield of core-1-positive polysaccharides accumulated by reverse phase chromatography was 30 %. Comparision of proportional monosaccharide contents of rough and purified capsular extracts revealed an increased amount of fucose, GalNAc/GalNH2, galactose and glucose, whereas glucose might be a contamination (table 7). The proportional content of rhamnose, GlcNH2/GlcNAc and mannose could be reduced by reverse phase chromatography (table 7). Galacturonic acid and glucuronic acid, which are characters components of capsular polysaccharides, could not be identified in the purified core-1-positive polysaccharide extract. These might indicate, thatB. ovatus AG6 have more than one capsular polysaccharide. Both capsular polysaccharides might be separated from each other by reverse phase chromatography. Tzianabos et al. (1992) also described, that the capsule of B. fragilis consists of two different polysaccharides.

Table 7: Monosacchride analyses of rough capsular polysaccharide extract (CPS) and core-1-positive polysaccharide extract purified by reverse phase chromatography. The proportional monosaccharide content is related to the total amount of monosaccharides.

[0316] The accumulation of fucose, GalNH2/GalNAc and galactose might be an indication, that these monosaccharides are components of the repeating units of the core-1-positive polysaccharide. Whereas the stongly reduced monosaccharides could be low contaminations. 10.4Structure analyses of the core-1 positive polysacchide by mass spectrometry [0317] The structure of core-1-positive polysaccharide was analysed by matrix-assisted laser time-off flight mass spectrometry (MALDI-TOF-MS) as already described above and by electrospray-Ion-Trap-mass spectrometry (ESI-Ion-Trap-MS).

[0318] For ESI-Ion-Trap mass spectrometry the accumulated core-1-positive polysaccharide was fragmentated either by hydrolysis with 1% acidic acid (l,5h, at 100°C) or enzymatic digestion with chondroitinase ABC (cleavage of ÅZÅ2l-4GalNAc/GlcNAc bounds) or with AZA2l-3 galactosidase. Furthermore, fragmentation by dobble digestion with chondroitinase ABC/AZA±l-3,4 fucosidase or 1% acidic acid / AZA2l-3 galactosidase occurred (all enzyms were received from Glyko GmbH). All enzymatic digestions were incubated at 37°C overnight. Mass spectrometric analyses (MS as well as MS/MS) were carried out in the positive and in the negative mode. Before analyses occurred, all samples were desalted by Carbograph SPE (Aalltech Associates Inc.) as described by manufactors manual and diluted in 2,5 mM NH3/ 40% acetonitril.

[0319] The structure of core-1-positive glycan fragments, which was already identified by MALDI-MS analyses, could be verified by ESI-Ion-Trap determination. Additional fragments could also be identified by ESI-Ion-Trap mass spectrometry (table 8).

Table 8: structure analyses by ESI-Ion-Trap mass spectrometry (positive mode). The purified core-l-positive polysaccharide was fragmentated by hydrolyses with 1% acidic acid for 1,5 h at 100°C.

[0320] The sequence of repeating units of core-l-positive capsular polysaccharide was determined by overlapping fragments (figure 6).

[0321] Mass spectrometric analyses of enzymatically digested core-l-positive polysaccharides gave indications of glycosidic bounds between the monosaccharides. Furthermore galactose (successful cleavage by AZA2l-3 galactosidase) and fucose (successful cleavage by AZA±l-3,4 fucosidase) could be identified (figure 7).

[0322] This result is in accordance with the monosaccharide analyses mentioned before, which revealed an accumulation of fucose, galactose and GalNAc. 10. S Versification of core-1-structure as branching disaccharide of repeating unit of capsular polysaccharide [0323] The branching core-1-structure, GalAZA2l-3GalNAc, in the repeating unit should be identified by double digestion with the exoglycosidases AZA2l-3 galactosidase and HexNAcase (AZA2l-2,3,4,6 GalNAc/GIcNAc cleavage) followed by monosaccharid analyses as described above.

[0324] Two samples containing equal amounts of core-1-positive polyssaccharide were filtrated to purify them from free monosaccharides. Afterwards one of both samples was digested with AZA2l-3 galactosidase at 37°C overnight. Both samples were filtrated once again to separate free galactose from the digested sample, whereas the undigested sample were used as negative control. Subsequently, the retentats were collected and digested with HexNAcase. Finally both sample were filtrated again. All eluates were analysed by HPAEC-PAD.

[0325] To control, if the oore-1-structure was removed by double digestion but was untouched by HexNAcase digestion (negative control), the retentates were analysed by dot-blot using the DIG-Glykan Detection Kit (Roche Diagnostics) to detect polysaccharides and the core-1-specific antibody Nemod-TFl to identify the core-1-structure.

[0326] In both eluats of double digested sample galactose (first eluat) and GalNAc (second eluat) could by identified by monosaccharid analyses. While in the eluat of negative control, which was only digested with the exoglycosidase HexNAcase, neither galactose nor GalNAc could be identified. These ist a strong indication for the branching core-1-structure, GalAZA2l-3GalNAc.

[0327] Dot-Blot analyses of double digested retentat and HexNAcase digested sample using the DIG-Glykan detection Kit revealed similar polysaccharid concentrations, which was applied on the nitrocellulose membrane. The core-1-structure could not detected in the dobble digested sample any more, whereas in the HexNAcase digested sample the core-1-structure was still identified by immunoblot using Nemod-TF I antibody. 10.6 Verification of the core-1-positive polysaccharide structure by analyses of its separated fragments.

[0328] For further verification of core-1-positive polysaccharide structure, the glykan was fragmentated by hydrolysis with 1 % acidic acid (1,5 h, 100°C). The glycan fragments were labeled by the fluorophore 2-amino benzamide (2-AB) as already described by J.C. Bigge et al. (1995). For this procedure, samples were rendered particle-free and salt-free by purification at Carbograph SPE column (Alltech Associates Inc.) and lyophilized. The pellet was dissolved in 5 μΙ 2-AB in DMSO/glacial acetic acid/ sodium cyanoborohydride and incubated at 60 °C for 2 h. The 2-AB labeled fragments were separated from free 2-AB by paper chromatography. Finally 2-AB conjugated fragments were eluted by water. After lyophilization the pellet was dissolved in 50% acetonitril. Based on their size, fragments were separated by normal phase HPLC (column: Luna 3μ NH2 A100, Phenomenex, eluent A: 15 mM NH4-acetat, eluent B: acetonitril) with fluorescence detection. The sequence of fragments was analysed by ESI mass spectrometry. Finally, for verification of glycosidic bonds and better identification of monosaccharides being components of the fragments, the oligosaccharides were digested with the exoglykosidase AZA2l-3 galactosidase, AZA±l-3,4 fucosidase and HexNAcase as already described before. The success of digestion was controled by ESI mass spectrometry and the removal of terminal monosaccharides was identified by HPAEC-PAD as already described before.

[0329] The already identified structure of repeating units of core-1-positive polysaccharide was confirmed by both analyses getting the expected oligosaccharide fragments and cleaved monosaccharides (table 9).

Table 9:

[0330] In conclusion, the structure of repeating units of core-l-positive capsular polysaccharide (fig. 8) was confirmed by a variety of analyses.

Example 11 Animal model 11.1 Intra-peritoneal immunization of mice with dead bacteria 11-1.1 Analysis of mouse sera by humoral immune response test 1 [0331] Female Balb/c mice (Charles River, 4 per group) were treated with Cydophosphamid at a dosis of 50 mg/kg body weight at day -1. At days 0, 7 and 14 mice were intra peritoneally injected with 5 x 108 bacteria (core-1 negative strains AG3 (group I), 32 or 53 or core-1 positive strain AG6 (group K)) in PBS or with PBS alone (group L). Serum samples were taken at days -4, 21, 27 and 30.

[0332] Mouse sera were analysed for binding to core-1 in ELISA. As Core-1 carrying antigen served asialoglycophorin. As a negative control periodic acid-treated asialoglycophorin was used. Periodate treatment destroys the outer carbohydrate ring of the core-1 thereby destroying the Core-1 epitope..

[0333] 96-well flat-bottom microtiter plates were coated with asialoglycophorin A (AGP) at a concentration of 2pg/ml. Plate was washed 3 times with PBS/Tween.

[0334] Half the plate was treated with periodate as follows: [0335] Wells were incubated for 5 minutes with 50mM sodium acetate buffer pH 4.5 followed by a lh incubation with lOmM periodic acid in acetate buffer in the dark. Wells were incubated for 5 minutes with 50mM sodium acetate buffer pH 4.5. Reaction was stopped by incubation with sodium borohydride (50mM in PBS, 30 min). Next, plates were washed 5 times with PBS/Tween.

[0336] Plates were then blocked by addition of 2% BSA for 30min.

[0337] Incubation with different dilutions of mouse sera were performed for l,5h. Bound mouse immunoglobulin was detected with a peroxidase-conjugated goat anti-mouse IgM antibody (1:5000 in PBS/1% BSA). Assay was developed with TMB as substrate and reaction was stopped by addition of 2,5 N H2SO4.

[0338] Fig. 9 shows the binding of serum IgM-antibodies to core-1 positive AGP and core-1 negative AGP (AGP+PJ). Only sera of three out of 4 mice immunized with Core-l-positive bacteria (group K) showed strong binding to AGP, whereas the signal is reduced after cleavage of Core-1 with PJ.

[0339] Therefore, core-l-positive bacteria are capable of inducing core-l-directed humoral immunity in mice. 11.1.2 Analysis of mouse sera by humoral immune response test 2 [0340] Male C3H mice (Charles River, 4 per group) were intra-peritoneally immunized with 5x108 pasteurized bacteria from Core-1 postive and Core-1 negative strains in 200pl PBS at days 0, 7 and 14. Sera were collected prior to immunization and at days, 13, 21 and 28 and analysed in humoral immune response test 2.

[0341] 96-well flat-bottom microtiter plates were coated with different carbohydrate-PAA conjugates (GlcNAcÅZÅ2l-2GalÅZÅ2l-3GalNAcÅZA±-PAA, FucAZÅ±l-2GalÅZÅ2l-3GalNAcAZÅ±-PAA, GalNAcÅZÅ±l-3GalÅZÅ2-PAA, GalÅZÅ±l-3-GalNAcÅZÅ2-PAA, Gal betal-3GalNAc alphal-PAA) at 5pg/ml in coating buffer (8,4 g/l NaHC03, 3,56g/l Na2C03, pH=9,49) and incubated over night at 4°C.

[0342] Plate was washed 3 times with PBS/Tween.

[0343] Plates were then blocked by addition of 2% BSA for 30min.

[0344] Incubations with different dilutions of mouse sera were performed for l,5h. Bound mouse immunoglobulin was detected with a peroxidase-conjugated goat anti-mouse IgM antibody (1:5000 in PBS/1% BSA). Assay was developed with TMB as substrate and reaction was stopped by addition of 2,5 N H2SO4.

[0345] Figure 10 shows the mean value of ELISA signals against the PAA conjugate Gal betal-3GalNAc alphal-PAA relative to the ELISA signal against GlcNAcÅZÅ2l-2GalÅZÅ2l-3GalNAcÅZÅ±-PAA, for sera from 4 mice per group at day 0 (pre-immune serum) and day 21 [relative ELISA signal is calculated after the equation : (ELISA signals against Gal betal-3GalNAc alphal-PAA) * 100/ (ELISA signal against GlcNAcÅZÅ2l-2GalÅZÅ2l-3GalNAcÅZÅ±-PAA)]. Sera were calculated as positive if immune serum showed an increase of at least 50% compared with the pre-immune serum. It could be shown that only the Core-1-positive strains AG6 and MUI induced a Core-1 specific humoral immune response in mice. 11.1.3 Analysis of mouse sera by humoral immune response test 3 [0346] Female Balb/c mice (Charles River, 4 per group) were treated with Cyclophosphamid at a dosis of 50 mg/kg body weight at day -1. At days 0, 7 and 14 mice were intra peritoneally injected with 5 x 108 bacteria (core-1 negative strains AG3 (group I), 32 or 53 or core-1 positive strain AG6 (group K)) in PBS or with PBS alone (group L). Serum samples were taken at days -4, 21, 27 and 30.

[0347] Flow cytometric analyses were performed in order to analyze binding of mouse sera to Core-1 positive and core-1 negative human tumour cell lines (NM-wt and NM-D4, respectively; NM-wt is the parental cell of NM-D4 as described in W02005/017130 A2 and EP1654353, NM-D4 is deposited at the DSMZ under DSM ACC2605). 3 x 105 cells per tube were pelleted and the pellet was resuspended in 50μΙ murine serum (diluted 1:50 in PBS/10%FCS), control antibody or PBS/10%FCS alone. Samples were incubated for 20 min at 4°C, washed with PBS and centrifuged. Next, cells were incubated with Cy3-conjugated goat anti-mouse-IgM antibody (Jackson Immuno Research, 1:200 in PBS/10%FCS) for 20 min at 4°C, washed with PBS and resuspended in 200μΙ PBS for flow cytometric analysis.

[0348] Fig. 11 shows the binding of IgM antibodies from mouse sera to the human cell lines NM-wt (Core-1 negative) and NM-D4 (core-1 positive). Whereas binding to the Core-1 negative NM-wt line is comparable between mice immunized with Core-1 negative bacteria (group I) and Core-1 positive bacteria (group K), there is a significantly stronger binding of 3 out of 4 mice from group K to the Core-1 positive NM-D4 line. This is indicative of the core-1 specificity of the humoral immune response in mice immunized with Core-1 positive bacteria. 11.2. Oral Immunization of germ free mice with live Core-1 positive bacteria [0349] Germfree C3H-mice were orally immunized with 2xl69 live bacteria of strain AG6 at days 2,3,4, 9,10,11, 16, 17 and 18. Serum samples were taken at day 0 (pre-immune sera) and at days 14 and 21 and analysed for AGP- specific IgM antibodies in humoral immune response test 1.

[0350] Immunized mice showed increased anti-core-1 titers compare to control mice as shown by binding of mouse sera to AGP coated microtiterplates. Detection of bound mouse IgM was performed with peroxidase-coupled anti-mouse-IgM antibodies. Specificity of the signal for core-1 was shown by the decrease of the ELISA signal after treatment with periodic acid (destroying the carbohydrate structure). After 14 or 21 days 3 out of 3 mice had elevated IgM-antibody levels to Core-1 whereas control mice showed no increase of ELISA signals to AGP in comparison to AGP +PJ as shown in figure 12. 11.3 Oral immunization of C3H mice with pasteurized Core-1 positive bacteria [0351] C3H-mice were orally immunized with 2x1ο11 (group A) or 2xl010 (group B) pasteurized bacteria of strain AG6 daily at days 0 to 28. Serum samples were taken at day -1 (pre-immune sera) and at days 13, 21, 28 and 35 and analysed for AGP- specific IgM antibodies in humoral immune response test 1.

[0352] Immunized mice showed increased anti-Core-1 titers compared to control mice as shown by binding of mouse sera to microtiterplates coated with GP or AGP (with and without treatment with periodic acid). Detection of bound mouse IgM was performed with peroxidase-coupled anti-mouse-IgM antibodies. Specificity of the signal for core-1 was shown by the decrease of the ELISA signal after treatment with periodic acid (destroying the carbohydrate structuredecrease of at least 30%) and by the lower signal against GP (increase of AGP signal of at least 50%).

[0353] It was shown that 5 out of 6 mice from group A and 5 out of 8 mice from group B had developed Core-1 specific antibodies by day 21 (fig. 13).

[0354] In humoral immune response test 3 mouse sera were analysed for binding to the Core-1 positive tumor cell line NM-D4 in comparison to the Core-1 negative cell line NM-wt by flow cytometry. 3 x 105 cells per tube were pelleted and the pellet was resuspended in 50μΙ murine serum (diluted 1:300 in PBS/1%BSA), control antibody or PBS/1%BSA alone. Samples were incubated for 60 min at 4°C, washed with PBS and centrifuged. Next, cells were incubated with biotin-conjugated goat anti-mouse-IgM antibody (Jackson Immuno Research; 1:200 in PBS/1%BSA) for 60 min at 4°C and washed with PBS. Following cells were incubated with Cy3-conjugated streptavidin (Jackson Immuno Research, 1:200 in PBS/1%BSA) for 60 min at 4°C and resuspended in 200pl PBS for flow cytometric analysis.

[0355] Results were calculated after the following formula: positive cells on NM-D4jnununesnum- % positive cells on NM-D4pre.jmmuncscnim) / (% positive Cells on NM-Wtimmune serum ” % positive Cells on NM-Wt prr-im.nune serum) ϋ [0356] Mouse sera with a quotient X > 10 were seen as positive (with % positive cells on NM-wtjmmune serum -% positive cells on NM-wtpre.jmmune serum-1)· [0357] At day 28, 11 of 13 mice had developed a humoral immune response against the Core-1 positive human tumor cell line NM-D4 as shown in fig. 14.

Example 12. Potential of Core-1 positive bacteria for the induction of a cellular immune response (in vitro) 12. Generation of functional dendritic cells [0358] Dendritic cell line NemodDC (pNM-DC) has been used as source for antigen presenting cells (APC). The pNM-DCs were differentiated into iNM-DC, followed by loading with bacterial lysates (BaLy) of following bacteria strains: AG6, MU1, 52 and 53. 50pg/ml of every BaLy was added together with maturation cytokines to the culture media and iNM-DC were differentiated to their mature status (mNM-DC).

[0359] More detailed, in the first step pNM-DC (1 x 105 /ml) were differentiated into iNM-DC by 7days incubation in NemodDC medium (70% MEM-AZA±, 20% FCS, 10% CM5637) with addition of 1000 U/ml of GM-CSF, 100 U/ml IL-4 and 2,5 ng/ml TNF-AZA±. Next, lxl06/ml of immature NM-DC (iNM-DC) were loaded either with bacteria lysates (50pg/ml), tumor cell lysates (lx 106 lysed tumor cells for loading on lx 106 NM-DC) or AGP- and GP-proteins (20pg/ml) and maturated for 2 days by addition of 75 ng/ml TNF-AZA±.

[0360] The maturation phenotype of mNM-DC is very important for successful T-cell activation and was tested by means of flow cytometry for expression of CDla, CDllc, CD14, CD40, CD35, CD80, CD83, CD86, CD116, HLA-ABC and HLA-DR. Only those DC which had phenotype correspondent to the phenotype of mature DCs were used for T-cell activation.

12.2 Generation of activated T cells against Core-1 and detection of GM-CSF (cellular immune response test 1) and TNF-ÅZÅ± (cellular immune response test 2) production using ELISA

[0361] After 7-10 days of priming of T lymphocytes with NM-DC loaded with Core-1-positive bacterial lysates, resulting T cells (0,7-lxl06 /ml) were restimulated with mNM-DC (1x10s /ml) loaded with Corel-positiv tumor cell lysates (50pg/ml). Following 48 hours of incubation supernatants were harvested and assayed using for evaluation of the cytokine production in response to human Core-1-positive tumor cell line NM-D4 the GM-CSF- and TNF-ÅZÅ±- BD OptEIA™ Kits.

[0362] The 96-well plates were pre-coated with 50μΙ of appropriate capture anti-human (GM-CSF or TNF-AZA±) antibodies diluted 1:250 in coating buffer. After washing and blocking steps, ΙΟΟμΙ of supernatants or standards were added to microwells and incubated for 2 hours at room temperature. For standard curve the recombinant human GM-CSF in concentrations 0; 7,8; 15,6; 31,2; 62,5; 125; 250pg/ml and the recombinant human TNF-AZA± in concentrations 0; 4,7; 9,4; 18,8; 37,5; 75; 150; 300 pg/ml were used. After washing, ΙΟΟμΙ prepared Working Detector solution per well were added, and plate was incubated I hour at room temperature. In the next steplOO μΙ TMB One-Step Substrate Reagent were added per well. After final incubation for 30 minutes and addition of 50μΙ of Stop Solution the extensions were read at 450nm.

[0363] The results demonstrated in figures 15A and B show clear evidence that T cells generated to Corelpositive bacteria lysates are able to recognise DC loaded with Corel-positive cell-lysat from human cell line NM-D4 by production of tumor-inhibitory cytokines such as TNF-alpha and GM-CSF. In contrast, very low level of cytokines was released in response to Corel-negative cell lysates. Moreover, this recognition was specifically inhibited through pre-incubation of lysate-loaded NM-DC with Corel-specific antibody. 12.3 ELISPOT assay for evaluation of the secretion of IFN-ÅZÅ3 by activated T lymphocytes directed against Core-1 (cellular immune response test 2) [0364] ELISpot assay was used for evaluation of IFN-ÅZÅ3 secretion in response to antigen specific stimulation. This assay allows the quantification of functional ability of the pre-sensitised T cells to recognise Corel antigens in an antigen specific manner.

[0365] The T lymphocytes were first activated in vitro by being co-cultured with DC loaded with bacterial lysates. After 7 to 10 days of priming, activated T cells were harvested and re-challenged with DC (in ratio T cell to DC 10:1) loaded with Corel-positive (NM-D4) and Corel-negative (NM-wt) human tumor cell lysates.

[0366] The wells of the ELISpot plate were pre-coated with mouse-anti-human-IFN-ÅZÅ3 -antibody (Mabtech-Kit) that binds to the nitrocellulose base of the ELISpot plate. The re-challenged T cells were transferred into the wells, and cytokines are released during the incubation period. IFN-ÅZÅ3 that is released locally around each T cell binds to, and is therefore 'captured' by the specific antibody. After 24 hours of incubation the cells were removed. A second anti-human-IFN-ÅZÅ3 antibody in concentration lpg/ml is added to the wells; this biotinylated antibody is coupled to an enzyme that is capable of converting a substrate into an insoluble coloured product. The plates are washed once more, and streptavidin conjugated with enzyme-AP in a concentration of lpg/ml is added. Finally a precipitating substrate BCIP+NBT is added and the plate is incubated until spots emerge at the side of the responding T cells. The coloured spots are counted and analysed using a digital-imaging system.

[0367] The results showed that T cells generated to Corel-positive bacterial lysates (AG6 and MU1) are able to recognise DC loaded with Corel-positive cell-lysat from human tumor cell line NM-D4 by production of tumor-inhibitory cytokine IFN-gamma (Fig. 16). Very low level of cytokines was released in response to Corel-negative cell lysates (R+DC/wt). Furthermore, the specificity of recognition of Corel-positive cell-lysat (R+DC/D4) was proved by blocking of cytokine release with the Core-1 specific antibody Nemod-TFl (R+DC/D4+Ak). 12.4 Cellular immune response test 3: T-Cell Proliferation Assay [0368] The sensitised and re-stimulated T cells as described above for ELISpot analysis, were transferred after incubation from ELISpot plate into 96-well plate and were assayed using the colorimetric Cell Proliferation Reagent WST-1 (Roche Molecular Biochemicals), whose tetrazolium salt is cleaved by mitochondrial enzymes so that the amount of dye developed (read at 450 nm) directly correlates to the number of metabolically active cells in the culture. Absorbance of culture medium plus wst-1 in the absence of cells was the blank position for the enzyme-linked immunosorbent assay reader. The procedure consists of one-step-adding of ΙΟμΙ per well of WST-Proliferation reagent (Roche) and incubation for 3 hours at 37°C following measurement at 450nm.

[0369] The results demonstrated in figure 17, show clear evidence that T cells generated to Corel-positive bacteria lysates, recognise DC loaded with Corel-positive cell-lysat from human tumor cell line NM-D4 as shown by specific proliferation. Moreover, this recognition was specifically inhibited through pre-incubation of lysate-loaded NM-DC with Corel-specific antibody. 12.5 Cellular immune response test 4: Immunofluorescence test for Core-1 presentation on DCs loaded with bacterial lysates [0370] In order to analyse the processing and presentation of Core-1 by bacterial lysate-loaded NM-DC, immunofluorescence analyses were performed using core-1 specific monoclonal antibodies (Nemod-TFl, NEMOD-TF2). The presentation of the processed Corel-antigen on the surface of the mature DC was demonstrated with help of Immunofluorescence. Immunofluorescence (IF) is a technique allowing the visualization of a specific antigen (Corel) on cells by binding a specific Core-1 antibody following by addition of a secondary antibody labeled with fluorochrome, which is used to recognize a primary antibody.

[0371] In the first step pNM-DC (1 x 105 /ml) were differentiated into iNM-DC by 7days incubation in NemodDC medium (70% MEM-AZA±, 20% FCS, 10% CM5637) with addition of 1000 U/ml of GM-CSF, 100 U/ml IL-4 and 2,5 ng/ml TNF-AZA±. Next, lx 106 /ml of immature NM-DC (iNM-DC) were loaded either with bacteria lysates (50pg/ml), tumor cell lysates (lxlO6 lysed tumor cells for loading on lxlO6 NM-DC) or AGP- and GP-proteins (20pg/ml) and maturated for 2 days by addition of 75 ng/ml TNF-AZA±.

[0372] Matured and antigen loaded DC were washed and lxlO6 cells per 50 μΙ were placed on the microtiterplate for immunofluorescence staining. 3pg/ml of Core-l-specific antibody (Nemod-TFl) diluted in culture medium (10%FCS) was incubated with cell suspension for 1 hour at room temperature. After washing steps 50μΙ 1:200 diluted secondary goat anti-mouse IgM, Cy3-labeled Ab (Jackson/Dianova) were added and incubated for 30 minutes. Following washing steps, 20 μΙ of cell suspension were placed into each well of a Multitest slide (10 wells, Roth).

[0373] Immunofluorescence stained samples were examined with an Axioplan 2 fluorescence microscope equipped with the digital camera AxioCam (Zeiss).

[0374] Fig. 18 shows positive Core-l-specific staining of the mature mNM-DC, which have processed AG6- and NM-D4-Corel-positive lysates; and negative immunofluorescence on mNM-DC loaded with Corel-negative lysates (AG3 and NM-wt).
