Question

Quizplus · Accepted Answer

PGIS (prostacyclin synthase) is the prostaglandin produced in the endothelium that acts as a vasodilator and potent inhibitor of platelet aggregation. It is produced in response to various stimuli, including shear stress, and helps to regulate blood flow through the vasodilatory effects on smooth muscle cells in blood vessels. It also inhibits platelet activation and aggregation by increasing cAMP, thus preventing thrombus formation.
