Abstract: Disclosed are antibodies and antigen-binding fragments that bind to a complementary peptide having an amino acid sequence that is encoded by the complement of a nucleotide sequence encoding thrombin or a portion thereof. Such antibodies and antigen-binding fragments can be agonists or antagonists of thrombin receptor-mediated events. Also disclosed are methods of using the agonist antibodies and antigen-binding fragments of the invention to activate the non-proteolytically activated thrombin receptor (NPAR) in a subject in need of such treatment. In addition, methods of using the antagonist antibodies and antigen-binding fragments of the invention to inhibit activation of the NPAR in a subject in need of such treatment are disclosed.

Abstract: Thrombin is now known to mediate a number of potent biological effects on cells bearing high-affinity thrombin receptors. These effects depend, at least in part, upon receptor occupancy signals generated by thrombin's interaction with the high affinity thrombin receptor. The present inventors have formulated synthetic thrombin derivatives capable of selectively stimulating or inhibiting thrombin receptor occupancy signals. The stimulatory thrombin derivatives to bind to cell surface thrombin receptors and stimulate DNA synthesis in cells treated with non-mitogenic concentrations of alpha-thrombin or phorbol myristate acetate. Thus, these peptides, which have both a thrombin receptor binding domain and a segment of amino acids with a sequence common to a number of serine proteases, appear to generate receptor-occupancy dependent mitogenic signals.

Abstract: These compositions are new synthetic peptides and antibodies which are potent chemotactic agents for human neutrophils, and methods for their use. The specificity of these peptides is amino acid sequence specific for binding to a heretofore unidentified receptor on the surface of neutrophils. Neutrophil response to this peptide is specific, since monocytes and fibroblasts do not show any expression of this receptor. Antibodies against these peptides block the chemotactic response. Such antibodies are useful to modulate neutrophil recruitment to a wound site for enhancing or inhibiting inflammation and early effects of wound healing.
