  • Publication number: 20100113748
    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. IL-17RC is a common receptor for IL-17A and IL-17F. The present invention includes methods of using a soluble IL-17RC receptor, IL-17RCx4 for treating inflammation.

  • Publication number: 20090156495
    Abstract: The present invention provides a newly identified B7 receptor, zB7R1 that functions as lymphocyte inhibitory receptor, which is a PD-1-like molecule and is expressed on T cells. The present invention also provides the discovery of zB7R1's ability to bind to CD155. Methods and compositions for modulating zB7R1-mediated negative signaling and interfering with the interaction of its counter-receptor for therapeutic, diagnostic and research purposes are also provided.

  • 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.

  • Publication number: 20080299129
    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: 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: 4871175
    Abstract: A portable and foldable two-piece alignment training device for golfers includes two sets of elongated strips, each set having three strips hingeably joined at their first ends. The two strip sets are joined together by an adjustable slide clip and placed on the ground to form an "I". The "I" pattern keys the golfer to align his swing thereto.
