P2 Receptor Expression Profiles in Human Vascular Smooth Muscle and Endothelial Cells.

Summary:P2 receptors mediate the actions of the extracellular nucleotides ATP, ADP, UTP, and UDP, regulating several physiologic responses including cardiac function, vascular tone, smooth muscle cell (SMC) proliferation, platelet aggregation, and the release of endothelial factors. P2 receptor char
