Abstract: Novel purinergic receptors are provided, having research, diagnostic and therapeutic applications. Also provided are nucleic acids encoding there receptors, as well as expression systems for their production.

Abstract: The present invention includes a novel subtype of the P2-purinergic receptor, referred to as the P2Y12 receptor. This receptor is expressed selectively in the platelets and brain, and couples to a pertussis toxin-sensitive G protein (Gi). Nucleic acids encoding the receptor and associated screening and therapeutic methods are also disclosed.

Abstract: Disclosed herein are nucleic acid sequences that encode novel polypeptides. Also disclosed are polypeptides encoded by these nucleic acid sequences, and antibodies, which immunospecifically-bind to the polypeptide, as well as derivatives, variants, mutants, or fragments of the aforementioned polypeptide, polynucleotide, or antibody. The invention further discloses therapeutic, diagnostic and research methods for diagnosis, treatment, and prevention of disorders involving any one of these novel human nucleic acids and proteins.

Abstract: A novel subtype of the P2-purinergic receptor, referred to as the P2U2 receptor, is disclosed. This receptor is activated by four of its agonists in the following order of specificity: UTP>UDP>ADP>ATP. Nucleic acids encoding the receptor, antibodies that bind to the receptor and associated screening and therapeutic methods also are disclosed.

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: Disclosed are polypeptides and nucleic acids encoding same. Also disclosed are vectors, host cells, antibodies and recombinant methods for producing the polypeptides and polynucleotides, as well as methods for using same.
