  • Publication number: 20090191214
    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 recombinant 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: 20090155271
    Abstract: The present invention relates antagonists of IL-17A and IL-17F. The antagonists of the invention are based on IL-17RC alone or on both IL-17RC and IL-17RA (“IL-17RC/IL-17RA”). Such antagonists serve to block, inhibit, reduce, antagonize or neutralize the activity of IL-17F, IL-17A, or both IL-17A and IL-17F. IL-17A and IL-17F are cytokines that are involved in inflammatory processes and human disease. IL-17RA is a receptor for IL-17A and IL-17RC is a common receptor for both IL-17A and IL-17F. The present invention includes soluble IL-17A and IL-17F anatagonists, as well as methods for using the same.

  • Patent number: 7501497
    Abstract: Molecules that interfere with the binding of a tumor necrosis factor receptor with its ligand, such as a soluble receptor, have proven usefulness in both basic research and as therapeutics. The present invention provides improved soluble transmembrane activator and calcium modulator and cyclophilin ligand-interactor (TACI) receptors.

  • Publication number: 20080241138
    Abstract: Disclosed are antagonists of IL-17A and IL-17F. The antagonists are based on soluble IL-17RA and IL-17RC fusion proteins, including hybrid soluble receptors comprising portions of both IL-17RC and IL-17RA (“IL-17RC/IL-17RA”). Such antagonists serve to block, inhibit, reduce, antagonize or neutralize the activity of IL-17F, IL-17A, or both IL-17A and IL-17F. Also disclosed are methods of using such antagonists for treating disease, particularly inflammatory diseases mediated at least in part by IL-17A and/or IL-17F.

  • Patent number: 7387780
    Abstract: A soluble receptor to IL-20 having two polypeptide subunits, IL-20RA (formerly called ZcytoR7) and IL-20RB (formerly called DIRS1). 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.

  • Patent number: 6641999
    Abstract: This invention concerns a family of chimeric antibodies with high affinities to a high molecular weight, tumor-associated sialylated glycoprotein antigen (TAG-72) of human origin. These antibodies have (1) high affinity animal VH and VL sequences which mediate TAG-72 binding and (2) human CH and CL regions. They are thought to produce significantly fewer side-effects when administered to human patients by virtue of their human CH and CL antibody domains. The nucleotide and amino acid sequences of VH&agr;TAG VH, CC46 VH, CC49VH, CC83 VH, and CC92 VH, and CC49VL, CC83 VL, and CC92 VL idiotype sequences are disclosed, as well as in vivo methods of treatment and diagnostic assay using these chimeric antibodies.

  • Patent number: 6544505
    Abstract: Interferons represent an important class of biopharmaceutical products, which have a proven track record in the treatment of a variety of medical conditions, including the treatment of certain autoimmune diseases, the treatment of particular cancers, and the enhancement of the immune response against infectious agents. To date, four types of interferons have been found in humans: interferon-&agr;, interferon-&bgr;, interferon-&ggr;, and interferon-&ohgr;. The present invention provides new forms of human and murine interferon, “interferon-&egr;,” which have applications in diagnosis and therapy.
