P2Y receptor

P2Y receptor is a type of purinergic receptor, denoted by the symbol P2Y. P2Y receptors are a family of G-protein coupled receptors that are activated by extracellular nucleotides such as adenosine triphosphate (ATP) and uridine triphosphate (UTP). They are present in a wide variety of tissues in the body, including the brain, heart, smooth muscle, and immune system.

Function

P2Y receptors play a crucial role in many physiological processes. They are involved in the regulation of platelet aggregation, vasodilation, apoptosis, immune response, and neurotransmission. They also play a role in the release of calcium from intracellular stores.

Subtypes

There are eight known subtypes of P2Y receptors: P2Y1, P2Y2, P2Y4, P2Y6, P2Y11, P2Y12, P2Y13, and P2Y14. Each subtype has a unique pharmacological profile and is activated by different nucleotides.

Clinical significance

P2Y receptors are potential therapeutic targets for a variety of diseases, including cardiovascular disease, cancer, neurodegenerative diseases, and inflammatory diseases. For example, P2Y12 inhibitors are used as antiplatelet drugs to prevent thrombosis in patients with acute coronary syndrome or stroke.
