Abstract: The present invention provides a porcine antigen that binds to human xenoreactive antibodies. The porcine antigen differs from the known porcine xenoantigens in that the antigen does not include an &agr;Gal epitope. The present invention also provides methods to purify the porcine antigen of the invention, as well as agents that bind to the antigen. The antigen may be used to generate antibodies against the antigen. The antigen is useful for detecting the presence of human xenoreactive antibodies against the antigen in blood and blood compositions, and antibodies against the antigen may be used to detect the presence of the antigen in samples. The invention also provides methods and pharmaceutical compositions for reducing a host rejection response to a porcine xenograft. Finally, a method to treat human blood or blood-derived compositions to reduce the level of human xenoantibodies is disclosed.
Abstract: This invention pertains to a method for treating ulcerative colitis. Specifically, the method comprises orally or rectally administering to a human having ulcerative colitis a therapeutically effective amount of an antibody which binds to a tropomyosin isoform associated with ulcerative colitis. In another embodiment, the invention pertains to a method for treating ulcerative colitis in a human which comprises the steps of (a) obtaining from a human a colon epithelial cell extract containing a tropomyosin isoform associated with ulcerative colitis; (b) purifying the tropomyosin isoform until the tropomyosin isoform is substantially homogeneous; (c) developing an antibody which binds to the tropomyosin isoform; and (d) orally or rectally administering to a human having ulcerative colitis a therapeutically effective amount of the antibody to bind to the tropomyosin isoform associated with ulcerative colitis.

Abstract: The present invention is directed to antibodies and antibody fragments that bind specifically to the active conformation of human von Willebrand factor. Most preferred are recombinantly produced single chain variable immunoglobulin fragments. Because the antibodies or antibody fragments act only at the sites of thrombus formation and do not interfere with the normal activity of circulating platelets, they are particularly well suited for use as antithrombotic agents in a wide variety of applications.

Abstract: Methods of detecting activated T-cells involve monitoring levels of MUC-1 mucin expression at the protein and/or mRNA level. Compositions for modulating immune function contain compounds that modulate the expression or function of MUC-1. Methods of treating disorders associated an inappropriate state of T-cell activation involve contacting a T-cell with a compound containing an inhibitor of MUC-1 expression or function.
Abstract: Methods and materials are disclosed for the production of purified, active recombinant human neutrophil protease, PR-3, via activation of a pro-form herein referred to as proPR-3. Human PR-3 is useful for discovering inhibitors of excessive release of mature, active TNF&agr;. Also disclosed are methods for the identification of inhibitors of the conversion of the pro-form of TNF&agr; to its mature active form.
