Abstract: The present invention is directed towards immunoglobulin polypeptides that specifically bind to the extracellular domain of the human type beta PDGF receptor. The binding of the immunoglobulin polypeptides to the receptor inhibits PDGF-induced (or stimulated) receptor activation as indicated by inhibition of receptor phosphorylation and dimerization, and by inhibition of PDGF-mediated mitogenesis, chemotaxis and migration of cells displaying the human PDGF type beta receptor on the cell surface. Nucleic acids encoding the immunoglobulin polypeptides are also included in the invention. The immunoglobulin polypeptides have diagnostic and therapeutic uses.

Abstract: The invention relates to novel compounds of formula (I) containing fused heterocyclic ring systems which are effective platelet ADP receptor inhibitors: In formula (I), W is carbon or nitrogen, wherein at least one W is a carbon; and Y is nitrogen, oxygen, or sulfur. Such compounds including pharmaceutically acceptable salts are useful in various pharmaceutical compositions for the prevention and/or treatment of cardiovascular disease particularly those related to thrombosis.

Abstract: Defined constructs of modified human platelet-derived growth factor receptor polypeptides are provided. Extracellular region domain structures are identified and modifications and combinatorial rearrangements of the receptor segments are provided. Both cell bound and soluble forms of modified segments are made available, as are methods for assays using them, allowing for screening of ligand analogues.

Abstract: This invention provides antibodies that bind to epitopes of human platelet-derived growth factor receptor (hPDGF-R) fragments, wherein the fragments comprise one or more platelet-derived growth factor (PDGF) ligand binding regions from extracellular domains D1, D2, and D3. Also provided are antibodies specific for domain D3, such as monoclonal antibodies directed to the intra-cysteine portion of domain D3.

Abstract: Methods and compositions are provided for treating several acute disease states associated with smooth muscle cell proliferation as well as the chronic process of atherogenesis utilizing oligopeptides corresponding to regions of the PDGF receptor protein. The oligopeptides can be used to block PDGF binding and activation for numerous applications, and can serve as immunogens to raise receptor-specific antibodies.
