  • Patent number: 8907068
    Abstract: The present invention relates to blocking the activity of IL-20 polypeptide molecules. IL-20 is a cytokine that is involved in inflammatory processes and human disease. IL-20RA/IL-20RB is a common receptor for IL-20. The present invention includes anti-IL-20 antibodies and binding partners, as well as methods for antagonizing IL-20 using such antibodies and binding partners.

  • Publication number: 20130315919
    Abstract: The present invention relates to blocking, inhibiting, reducing, 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.

  • Publication number: 20130266562
    Abstract: Novel compositions derived from antigen-binding sites of immunoglobulins having affinity for IL-31 are provided. The compositions exhibit immunological binding properties of antibody molecules capable of binding specifically to a human IL-31. CDR regions derived from same or different immunoglobulin moieties are provided. Also provided are single chain polypeptides wherein VH and VL domains are attached. The sFv molecules can include ancillary polypeptide moieties which can be bioactive, or which provide a site of attachment for other useful moieties. The compositions are useful in specific binding assays, affinity purification schemes, drug or toxin targeting, imaging, and genetic or immunological therapeutics for inflammatory diseases. The invention thus provides novel polypeptides, the DNAs encoding those polypeptides, expression cassettes comprising those DNAs, and methods of inducing the production of the polypeptides.
