Method of treating autoimmune conditions are disclosed comprising administering to a mammalian subject IL-12 or an IL-12 antagonist. In certain preferred embodiments the autoimmune condition is one which is promoted by an increase in levels of IFN-&#x3b3; or TNF-&#x3b1;. Suitable conditions for treatment include multiple sclerosis, systemic lupus erythematosus, rheumatoid arthritis, autoimmune pulmonary inflammation, Guillain-Barre syndrome, autoimmune thyroiditis, insulin dependent diabetes melitis and autoimmune inflammatory eye disease.

Use of IL-12 and IL-12 antagonists in the treatment of autoimmune diseases

The instant invention provides compositions and methods for downmodulation of immune responses, e.g., autoimmune responses. For example, methods of downmodulating an immune response using agents that specifically block CD28-mediated signaling are provided. The subject methods are useful for both prophylactic and therapeutic downmodulation of immune responses.
