Description: METHODS AND COMPOSITIONS FOR MODULATING IMMUNE RESPONSE AND FOR THE TREATMENT OF INFLAMMATORY DISEASE BACKGROUND OF INVENTION This invention relates to the use of N,N-dιmethylglycme (DMG) in combination with at least one component denved from Perna canaliculus to modulate immune responses and to treat inflammatory diseases in man or animals N' N-dimethylglycine (DMG), which is a tertiary ammo acid, is an intermediary metabolite found in low levels in many foods. It is produced m the body from chohne and has been used as a non-fuel nutπent The physiological and potential therapeutic effects of N,N-dιmethylglycine have been evaluated in recent years. References in the literature pertaining to N,N-dιmethylglycme and its potential uses include the following: Graber et al., 1981, J. of Infectious Diseases 143:101-105 (DMG stimulation of both humoral and cellular immunity), Kendall and Graber, U.S Pat.

years since the mid-seventies The nutπtional and therapeutic properties of freeze-dπed Perna canaliculus in alleviating the symptoms of arthritis were reported in Croft, 1979, Relief From Arthritis (Thorsons Publishing Group, Rochester, Vermont) Studies in both animal and human expeπments have given mixed results, but indicate overall that certain components in the mussels were potentially helpful in relieving inflammation and pain associated with arthritis Certain of these studies are as follows McFarlane, June 1975, New- Zealand Medical Journal, pg 569 (the results of a study of the effects of a Perna canaliculus product called "Seatone" on a small group of arthritic individuals were reported), Ramsford and Whitehouse, 1980, Arzeim-Forsch, pg 2128-2131 (a freeze-dπed powdered

discovered that a combination of N,N-dιmethylglycιne (DMG) and a component derived from Perna canaliculus (referred to herein as Perna canaliculus extract (PCE)) has a synergistic effect in the treatment of inflammatory disease In particular, it has been discovered that the combination has a synergistic effect in the treatment of autoimmune disease, including lupus erythmatosus, and m the modulation of immune responses to inflammatory disease Also in accordance with this invention it has been discovered that the aberrant immune response profiles in humans with rheumatoid arthπtis or osteoarthπtis may be beneficially altered by the administration of a combination of DMG and PCE Treatment, as used herein, pertains to the therapeutic administration of the compounds of the invention for the prevention, amelioration, or cure of disease Inflammatory diseases that may be treated in accordance with this invention include systemic autoimmune diseases such as, for example, lupus erythmatosus, rheumatoid arthπtis, and multiple sclerosis, and organ specific autoimmune diseases such as, for example, myasthenia gravis, Grave's disease, Hashimoto's thyroiditis, Crohn's disease, autoimmune hemolytic anemias, insulin dependent diabetes mellitus, glomerulonephπtis, and rheumatic fever Other inflammatory diseases that may be treated in accordance with this invention include other inflammatory arthπtic conditions such as osteoarthπtis and gouty arthπtis, as well as other inflammatory conditions such as conjunctivitis, dermatitis, bronchitis, rhinitis etc , brought about by injury, allergies, infections, microorganisms, trauma, or physical or chemical agents Additionally, the treatment of inflammatory aspects of asthma is also contemplated as part of this invention One aspect of the invention is a composition compπsing a combination of a DMG component and at least one PCE component The PCE component may be am therapeutically active component derived from the flesh of the mussel or its organs, which are suitable for use in the preparation of food supplements or pharmaceutical preparations. The invention contemplates the use of unrefined components of the mussel, such as whole mussel, or any therapeutically active extracts thereof. As used herein, a therapeutically active PCE component according to this invention is a component that is effective in reducing inflammation in animals or humans or that has immunomodulating effects in humans or animals. For example, several animal models for arthritis that are well known in the art may be used to determine therapeutic activity of a PCE component. Such models include, for example, collagen induced arthritis in rats or mice, carrageenan-induced inflammatory oedema in rats as described in Miller et al., 1980, New Zealand Medical Journal 92:667, and arthritis induced in rats and mice by the injection of adjuvants prepared from dried Mycobacterium tuberculosis as described in Whitehouse, et al., 1997, Inflammopharmacology 5:237-246. Therapeutic activity of a PCE component may also be determined by evaluating whether the PCE component is effective for reducing anti-nuclear antibodies, particularly anti-ssDNA antibodies or anti-dsDNA antibodies, in humans with SLE or in the mouse model for SLE, as described in the examples. In particular, the PCE may be a preparation of whole mussel which has been freeze-dried and ground such as, for example, the Sea Mussel product available from FoodScience Corporation, Essex Junction, Vermont or the Perna product available from DaVinci Laboratories, Essex Junction, Vermont. Additionally, therapeutically active extracts of Perna canaliculus may also be employed. Such therapeutically active extracts have been described as follows: Macrides and Kalafatis, PCT/AU95/00485, WO 96/05164 (a purified Hpid extract); Whitehouse et al., 1997, Inflammopharmacology 5:237-246 (a purified lipid extract); Kosuge and Sugiyama, U.S. Patent No. 4,801,453 (stabilized mussel extract); Couch et al., 1982, 77ze New Zealand Medical Journal 95:803 (a protein fraction); Miller et al., 1993, Agents Actions 38: 139 (an aqueous fraction). The DMG component may be Ν,Ν-dimethylglycine or a pharmacologically acceptable salt thereof. A composition containing both DMG and PCE may be formulated as a pharmaceutical or dietary supplement using techniques that are well known in the art. A preferred formulation of the composition is a formulation for oral administration. Another aspect of this invention is a method of treating inflammatory disease comprising administering to an animal a combination of both a DMG component and at least one PCE component. As used herein, the term animal includes, but is not limited to, mammals. Preferred mammals include humans, horses, farm animals and household pets. The DMG and PCE components may be administered via the same route or they may be administered via different routes. For example, the DMG and PCE may both be administered orally, either simultaneously or at different times. A preferred route for administration of PCE, particularly ground whole mussel, is via oral administration. A preferred route for the administration of DMG is via oral administration, particularly as an admixture with water. DMG or PCE can also be administered by intramuscular injection, intra peritoneal injection, parenteral administration, etc. The DMG and PCE used in this invention can be employed in admixture with conventional excipients, i.e. pharmaceutically acceptable organic or inorganic carrier substances suitable for parenteral, enteral (e.g., oral) application which do not deleteriously affect the active compound. Suitable pharmaceutically acceptable carriers include but are not limited to water, salt solutions, alcohols, gum arabic, vegetable oils, benzyl alcohols, polyethylene glycols, gelatine, carbohydrates such as lactose, amylose or starch, magnesium sterate, talc, silicic acid, viscous paraffin, perfume oil, fatty acid monoglycerides and diglycerides, pentaerythritol fatty acid esters, hydroxy methylcellulose, polyvinyl pyrrolidone, etc. The pharmaceutical preparations can be sterilized and, if desired, mixed with auxiliary agents such as, for example, lubricants, preservatives, stabilizers, wetting agents, emulsifiers, salts for influencing osmotic pressure, buffers, coloring agents, flavoring agents and/or aromatic substances and the like which do not deleteriously affect the active compound. Other pharmaceutically acceptable carriers include aqueous solutions, non toxic excipients, including salts, preservatives, buffers and the like, as described for instance, in Remington 's Pharmaceutical Sciences, 18th ed. (1990). Mack Publishing Co., Easton, PA, the contents of which are hereby incorporated by reference.

Without further elaboration, it is believed that one skilled in the art can, using the preceding description, utilize the present invention to its fullest extent. The following preferred specific embodiments are, therefore, to be construed as merely illustrative, and not limitative of the remainder of the disclosure. E M P S In the following examples, all parts and percentages are by weight unless otherwise indicated. Example 1 - Preparation of a therapeutically active PCE component A therapeutically active formulation of Perna canaliculus is prepared by freeze-drying the flesh of the mussel and grinding it into a powder. The product is formulated into capsules with the excipients of alfalfa, cellulose and magnesium stearate. Example 2 - Treatment of systemic lupus erythmatosus with a combination of DMG and PCE extract. Systemic lupus erythmatosus (SLE) is considered to be the prototypic autoimmune disease. SLE is characterized by various degrees of severity with mild forms resulting in minor skin rash and joint pain and severe forms resulting in glomerulonephritis, immune complex disease, severe lymph node enlargement, and multiple organ failure. SLE is further characterized by the development of auto- antibodies against cytoplasmic and nuclear components. In addition to clinical symptoms, the presence of anti-nuclear antibodies is a hallmark of the disease, and its presence is an important indication in the diagnosis of the disease (Tan, 1989, Adv. Immunolog}- 44:93). MRI-lpr mice are an accepted and well documented model for SLE (Cohen and Eisenberg, 1991 , Ann. Rev. Immunol 9:203; Kotzin, 1996, Cell 85:303). These mice display a homozygous genetic defect in the Fas-TNF receptor related to apoptosis. Fas protein is an important pathway for the induction of apoptosis and the Fas protein is responsible for lymphocyte removal. These mice produce a broad spectrum of auto-antibodies against nuclear and cytoplasmic proteins. and the MRI-lpr mice die from classical lupus-like symptoms. MRI-lpr mice were used to study the effects of a combination of DMG and PCE on components of the immune system and on the progression of the SLE disease. Forty MRI-lpr mice were divided into four groups of ten mice each: a control group, a PCE treated group, a DMG treated group, and a PCE-DMG treated group. The control group was given standard mouse chow and water. The DMG group was given standard mouse chow and water mixed with 34 mg/L of DMG (AANGAMIK® DMG, FoodScience Corporation, Essex Junction, Vermont). The PCE group was given a PCE-mouse chow mix and water. The PCE-DMG combination group was given a PCE-mouse chow mix and DMG water. The PCE supplement used in the studies was a product containing freeze-dried, ground whole Perna canaliculus mussel (Perna, FoodScience Corporation, Essex Junction, Vermont). The mice were given food and water ad libitum. It is estimated that the mice, with a size range of SO- 50 grams, consumed about 1-3 mg/day of DMG and 2-6 mg/day of PCE. The mice were weighed weekly and 100 ul of blood was collected via orbital bleed on a weekly- basis. The collected blood was centrifuged and the serum was recovered and stored at -20 °C for analysis at the end of the twelve week experiment. After twelve weeks, the mice were sacrificed and the spleens, kidneys, and livers were harvested. When the mice were sacrificed, blood was also collected via a cardiac stick. The serum was collected and stored as described above. The spleens were processed and the cells recovered were quantified by flow cytometry using fluorescent anti-CD4, anti-CD8 and anti-CD19 antibodies (Pharmingen, San Diego, CA). Cytokine levels in the serum and anti-single stranded and double stranded DNA antibody levels in the serum were determined using an enzyme linked immunosorbent assay (ELISA). Animals whose diets were supplemented with PCE alone or the DMG-PCE combination experienced a higher weight gain than control or DMG treated animals, indicating that the mice treated with the combination were not adversely affected by the treatment (Figure 1). A significant decrease in CD8 * T cells was noted with animals fed the standard DMG-PCE combination, with a trend toward lower levels in animals fed only PCE (Figure 3). A trend toward lower CD 19" B cell percentages was also observed with DMG-PCE treated animals, while animals treated with PCE alone had CD 19" B cell levels comparable to those of controls. No effect of DMG alone on CD8" T-cell or CD19 ' B-cell levels could be detected (Figure 3). The effects on cytokine production in mice treated with the DMG-PCE combination was also examined. As shown in Figure 2, animals treated with the DMG-PCE combination showed significantly lower levels of serum il-6 than either control animals or animals treated with DMG alone. Although animals treated with either DMG or PCE alone had significantly lower levels of il-6 than control animals, animals treated with a combination of the two had even lower levels. DMG-PCE treated animals also showed significantly lower levels of serum il-10 than either control animals or animals treated with either DMG or PCE alone. These changes in cytokine serum levels are indicative of a shift from a Th2 response to a Thl response. The significant rise in serum levels of tumor necrosis factor (TNF) in DMG-PCE treated animals is also indicative of this shift from a Th2 response to a Thl response. Treatment of animals with DMG alone resulted in higher levels of IL-10 than in controls, indicating a shift toward a Th2 response. Although DMG is a known enhancer of antibody production, it is not known whether the enhanced antibody production observed represents pathological IgG2a production. Levels of serum il-10 and TNF-α were comparable in control animals and in animals treated with PCE alone. Therefore, DMG-PCE treatment appeared to shift the lymphocyte response from a Th2 response to a Thl response, with a concomitant decrease in excess antibody production, including anti-nuclear antibody production as discussed below. Levels of anti-nuclear antibodies were also examined in control and treated mice. After eleven weeks of treatment, anti-dsDNA antibody levels in the serum of DMG-PCE treated animals were significantly lower than in control animals or in animals treated with DMG alone or PCE alone (Figure 4). Even more significantly, anti-ssDNA antibody levels in the serum of DMG-PCE treated animals were in tandem with levels in control animals until the 7th week, when these serum concentrations were found to be lower (Figure 5). This significant difference was observed to continue until animals were euthanized after the 1 1th week. Serum levels of anti-ssDNA antibodies in control animals and in animals treated with PCE alone continued to increase throughout the course of treatment. By the 11th week, serum levels in animals treated with DMG alone appeared to be leveling out. Example 3 - Comparison of lymphocyte populations in healthy human subjects with lymphocyte populations in human subjects with osteoarthritis or rheumatoid arthritis. Lymphocyte populations were measured and compared in healthy human subjects versus human subjects with osteoarthritis or rheumatoid arthritis (Figure 6). Lymphocyte populations measured included total T cells (T Cells), helper T cells (Th) (CD4 cells), cytotoxic T cells (Tc) (CD8 + cells), B cells (B), and natural killer cells (NK). The cell populations were identified by external staining of whole blood lymphocytes using the following antibodies: anti-CD3 antibodies for total T cells; anti-CD4 antibodies for helper T-cells; anti-CD8 antibodies for cytotoxic T; anti-CD5 and anti-CD 19 antibodies for B cells; anti-CD56 antibodies for natural killer cells; and anti-CD45 antibodies for monocytes. The antibodies were obtained from either Caltag Corp. or Coulter Corp. and were tagged for analysis on an EPICs 751 flow cytometer (Coulter FI) with a Cicero acquisition module and cyclops analysis software (Cytomation, CA). As shown by the data in Figure 6, a CD47CD8 * T cell switch was observed in both diseases when compared to healthy controls, with a significant decrease in CD4 + cells in subjects with either disease and a significant mcrease in CD8 cells in subjects with either disease Example 4 - Companson of cytokine concentrations in healthy human subjects with cytokine concentrations in human subjects with osteoarthntis or rheumatoid arthntis. Cytokine levels were measured and compared in healthy human subjects versus human subjects with osteoarthritis or rheumatoid arthritis (Figure 7) Cytokines measured included gamma interferon, interleukin 1 - beta, mterleukm 2 mterleukm 4, interleukin 6, mterleukm 10 and TNF-α Cytokines w ere measured using specific ELISA kits according to the manufacturers instructions (Immunotech, France) Interleukin 6 levels were significantly higher in subjects w ith either disease than for control subjects TNF-α levels were significantly increased m subjects with rheumatoid arthπtis compared to normal controls, but were not increased in patients with osteoarthπtis The preceding examples can be repeated with similar success by substituting the genencally or specifically described reactants and/or operating conditions of this invention for those used in the preceding examples Without further elaboration, it is believed that one skilled in the art can, using the preceding descnption, utilize the present invention to its fullest extent The preceding preferred specific embodiments are. therefore, to be construed as merely illustrative, and not limitative of the remainder of the disclosure m any way whatsoever The entire disclosure of all patent applications, patents, and publications cited herein are hereby incorporated by reference From the foregoing descnption, one skilled m the art can easily ascertain the essential characteristics of this invention and, without departing from the spirit and scope thereof, can make various changes and modifications of the invention to adapt it to vaπous usages and conditions
