20080233115ANTI-IL-20 ANTIBODIES AND BINDING PARTNERS AND METHODS OF USING IN INFLAMMATION - The present invention relates to blocking, inhibiting, reducing, antagonizing or neutralizing the activity of IL-20 polypeptide molecules. IL-20 and IL-22 are cytokines that are involved in inflammatory processes and human disease. The present invention includes anti-IL-20 and anti-IL-22RA antibodies and binding partners, as well as methods for antagonizing IL-20 using such antibodies and binding partners.09-25-2008
20090018080METHODS FOR TREATING VIRAL INFECTION USING IL-28 AND IL-29 CYSTEINE MUTANTS - IL-28A, IL-28B, IL-29, and certain mutants thereof have been shown to have antiviral activity on a spectrum of viral species. Of particular interest is the antiviral activity demonstrated on viruses that infect liver, such as hepatitis B virus and hepatitis C virus. In addition, IL-28A, IL-28B, IL-29, and mutants thereof do not exhibit some of the antiproliferative activity on hematopoietic cells that is observed with interferon treatment. Without the immunosuppressive effects accompanying interferon treatment, IL-28A, IL-28B, and IL-29 will be useful in treating immunocompromised patients for viral infections.01-15-2009

IL-20 and IL-22 are cytokines that are involved in inflammatory processes and human disease. IL-22RA (zcytor11) is a common receptor for IL-20 and IL-22. The present invention includes anti-IL-22RA antibodies and binding partners, as well as methods for antagonizing IL-22 or both IL-20 and IL-22 using such antibodies and binding partners.03-19-2009
20090075341IL-21 ANTAGONISTS - Monoclonal antibodies are identified that bind the IL-21 protein. These antibodies are used to identify regions of the IL-21 protein to where binding neutralizes IL-21 activity. Hybridomas and methods of producing anti-IL-21 monoclonal antibodies are described. The monoclonal antibodies are useful in treating IL-21-mediated diseases, which may include autoimmune and inflammatory diseases such as pancreatitis, type I diabetes (IDDM), Graves Disease, inflammatory bowel disease (IBD), Crohn's Disease, ulcerative colitis, irritable bowel syndrome, multiple sclerosis, rheumatoid arthritis, diverticulosis, systemic lupus erythematosus, psoriasis, ankylosing spondylitis, scleroderma, systemic sclerosis, psoriatic arthritis, osteoarthritis, atopic dermatitis, vitiligo, graft vs. host disease (GVHD), cutaneous T cell lymphoma (CTCL), Sjogren's syndrome, glomerulonephritis, IgA nephropathy, graft versous host disease, transplant rejection, atopic dermatitis, anti-phospholipid syndrome, and asthma, and other autoimmune diseases.03-19-2009
