  • Patent number: 8124089
    Abstract: Human anti-human IL-21 monoclonal antibodies and the hybridomas that produce them are presented. Certain of these antibodies have the ability to bind native human IL-21, a mutant recombinat IL-21 protein and/or peptide regions of human IL-21. These human anti-IL-21 antibodies are useful in therapeutic treatment of autoimmune and inflammatory diseases, particularly diseases mediated by T follicular helper cells, B cells TH cells or TH17 cells.

  • Publication number: 20110177083
    Abstract: The present invention relates to blocking, inhibiting, reducing, antagonizing or neutralizing the activity of IL-17F, IL-17A, or both IL-17A and IL-17F polypeptide molecules. IL-17A and IL-17F are cytokines that are involved in inflammatory processes and human disease. ZcytoR14 is a common receptor for IL-17A and IL-17F. The present invention includes soluble ZcytoR14, anti-ZcytoR14 antibodies and binding partners, as well as methods for antagonizing IL-17F, IL-17A or both IL-17A and IL-17F using such soluble receptors, antibodies and binding partners.

  • Publication number: 20110172399
    Abstract: 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.

  • Patent number: 7977309
    Abstract: The present invention is directed to polynucleotides, polypeptides and peptide fragments thereof, and uses thereof for a novel cDNA sequence which has homology to motilin. Tissue distribution of the mRNA for the novel polypeptide is specific to the stomach, small intestine and pancreas. The present invention further includes agonists, antagonists, antibodies, host cells expressing the cDNA encoding the novel motilin homologs and methods for increasing gastric motility using the novel molecules.

  • Publication number: 20110159589
    Abstract: The present invention relates to blocking, inhibiting, reducing, antagonizing or neutralizing the activity of IL-17A, IL-17F, and IL-23. Antagonists include antibodies and antibody fragments that bind IL-23 and that bind IL-17A or IL-17F, such as antibodies that are cross-reactive for IL-17A and Il-17F. Antagonists that include an antibody or antibody fragment that binds IL-23 and an antibody or antibody fragment that binds IL-17A or IL-17F on one molecule are also disclosed. Antibodies and antibody fragments that bind IL-23 and IL-17F but that do not bind IL-17A are also disclosed. IL-17 and IL-23 are cytokines that are involved in inflammatory processes and human disease.

  • Publication number: 20110150872
    Abstract: A soluble receptor that binds to IL-20 having two polypeptide subunits, IL-22R and IL-20RB. The two subunits are preferably linked together. In one embodiment one subunit is fused to the constant region of the light chain of an immunoglobulin, and the other subunit is fused to the constant region of the heavy chain of the immunoglobulin. The light chain and the heavy chain are connected via a disulfide bond.
