Abstract:
An agonist of a non-proteolytically activated thrombin receptor can be used in a method for treating peripheral arterial disease. The agonist can be a thrombin peptide derivative. In some embodiments, the peripheral arterial disease is characterized by intermittent claudication. The thrombin peptide derivatives to be used in the methods can have amino acid sequences similar to a region of thrombin. Usually, the thrombin peptide derivatives are 12-23 amino acid residues in length. In some cases, the thrombin peptide derivatives are dimers, and in particular, dimers that result from formation of a disulfide bond between two cysteine residues of peptide monomers.
Abstract:
Endothelial dysfunction (ED) is associated with a number of diseases and disorders. Agonists of the non-proteolytically activated thrombin receptor can be used in methods to treat ED or ED-related diseases and disorders.
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 subj ect in need of such treatment are disclosed.
Abstract:
Disclosed is a method of promoting healing of a chronic dermal skin ulcer, such as a diabetic ulcer, on a subject. The method comprises the step of contacting the chronic dermal skin ulcer with an effective amount of an agonist of the non-proteolytically activated thrombin receptor.

Abstract:
Agonists of a non-proteolytically activated thrombin receptor, and more particularly, thrombin peptide derivatives, can be used in methods to cause smooth muscle relaxation. Compositions comprising thrombin peptide derivatives can be administered to a subject with a disease or disorder that can be ameliorated by relaxation of smooth muscle. Such compositions can also be administered to a subject to facilitate medical, diagnostic or surgical procedures.
Abstract:
Disclosed are thrombin peptide derivative dimers comprising two polypeptides having the amino acid sequence Arg-Gly-Asp-Ala-Cys-Glu-Gly-Asp-Ser-Gly-Gly-Pro-Phe-Val (SEQ ID NO:2), or a C-terminal truncated fragment of the polypeptide having at least six amino acids. Zero, one, two, or three amino acids in the polypeptide or polypeptide fragment differ from the corresponding position of SEQ ID NO:2. Also disclosed are methods of treating a subject in need of treatment with a thrombin receptor agonist. The methods comprise the step of administering an effective amount of the thrombin peptide derivative described above.
