Combination therapy of beta-glycolipids and antibodies for the treatment of immune-related disorders
The present invention relates to a combination therapy for the treatment of immune-related disorders. More particularly, the invention relates to oral or mucosal synergistic compositions combining beta-glycolipids, preferably, β-glycosphin-golipids with immunoglobulin molecules specific for at least one antigen derived from a component of the immune system, specifically an anti-CD3 antibody. The invention further provides methods kits and uses of the combined compositions of the invention for immune-modulation and thereby for the treatment of immune-related disorders. In a preferred embodiment, anti-CD3 antibody (OKT3) is orally administered in combination with β-glucosylceramide (also known as glycocerebroside) in an animal model of type 2 diabetes.
1. A method of treating non-alcoholic fatty liver disease in a subject, the method comprising
selecting a subject who has non-alcoholic fatty liver disease; and
orally administering to the subject a therapeutically effective amount of a composition, wherein the active ingredients in the composition consist of an anti-CD3 monoclonal antibody, or antigen-binding fragment thereof, and
glucosylceramide (GC).
2. The method of claim 1 , wherein said orally administering said therapeutically effective amount of said composition comprises administering said composition in a therapeutically effective amount to reduce fat accumulation in the liver.
3. The method of claim 1 , wherein said orally administering said therapeutically effective amount of said composition comprises administering said composition in a therapeutically effective amount to reduce a level of at least one liver enzyme.
4. The method of claim 1 , wherein said therapeutically effective amount is sufficient to decrease at least one of IL-2, IL-17, IL-23, IFN-γ, IL-6 and to increase at least one of TGF-β and IL-10.
5. The method according to claim 1 , wherein said therapeutically effective amount is sufficient to modulate a Th1/Th2, Th3 cell balance in the subject.
6. The method according to claim 5 , wherein said therapeutically effective amount modulates the Th1/Th2, Th3 cell balance toward an anti-inflammatory Th2, Th1/Th3 immune response in the subject.
