  • Publication number: 20060269551
    Abstract: A method for treating IL-20 induced inflammation. An antagonist to IL-20 is administered to treat inflammation and associated diseases. The antagonist can be an antibody that binds to IL-20 or its receptor or a soluble receptor that binds to IL-20. Examples of such diseases are adult respiratory disease, psoriasis, eczema, contact dermatitis, atopic dermatitis, septic shock, multiple organ failure, inflammatory lung injury, bacterial pneumonia, inflammatory bowel disease, rheumatoid arthritis, asthma, ulcerative colitis and Crohn's disease.

  • Publication number: 20060263851
    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.

  • Publication number: 20060177447
    Abstract: The present invention relates to blocking, inhibiting, reduceing, antagonizing or neutralizing the activity of IL-22, IL-20, or both IL-20 and IL-22 polypeptide molecules. 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.

  • Patent number: 7084253
    Abstract: The present invention relates to polynucleotide and polypeptide molecules for PAR4, a novel member of the protease-activated receptor family. The polypeptides, and polynucleotides encoding them, mediate biological responses and/or cellular signaling in response to proteases. Protease cleavage of PAR4 exposes a PAR4 extracellular amino terminal portion that serves as a ligand for the PAR4 receptor. PAR4 may be used as a target in drug screening, and further used to identify proteinaceous or non-proteinaceous PAR4 agonists and antagonists. The present invention also includes antibodies to the PAR4 polypeptides.

  • Publication number: 20060067933
    Abstract: Soluble, secreted tumor necrosis factor receptor polypeptides, polynucleotides encoding the polypeptides, and related compositions and methods are disclosed. The polypeptides comprise one cysteine-rich repeat that is homologous to other tumor necrosis factor receptors, such as transmembrane activator and CAML-interactor (TACI). The polypeptides may be used for detecting ligands, agonists and antagonists. The polypeptides may also be used in methods that modulate B cell activation.

  • Publication number: 20050266485
    Abstract: Novel polypeptides, polynucleotides encoding the polypeptides, and related compositions and methods are disclosed for zcytor19, a novel class II cytokine receptor. The polypeptides may be used within methods for detecting ligands that stimulate the proliferation and/or development of hematopoietic, lymphoid and myeloid cells in vitro and in vivo. Ligand-binding receptor polypeptides can also be used to block ligand activity in vitro and in vivo. The polynucleotides encoding zcytor19, are located on chromosome 1p36.11, and can be used to identify a region of the genome associated with human disease states. The present invention also includes methods for producing the protein, uses therefor and antibodies thereto.
