Prostaglandin I2 (prostacyclin).

Open full text 39 citations

Abstract

Prostaglandin I2 (PGI2), or prostacyclin, is a recently discovered prostaglandin that affects many organ systems. It is both a potent inhibitor of platelet aggregation and a powerful vasodilator. The recent demonstration that it is the main prostaglandin synthesized by the blood vessel wall suggests that it may play an important role in limiting platelet-mediated thrombosis. However, despite considerable investigation, the exact physiological role of PGI2 has yet to be elucidated.
