2023年8月28日 · Prostaglandin I2 (PGI), or prostacyclin, is one of the prostanoids, a group of local hormones that are best known for their roles in mediating inflammation. However, they also perform many other roles in maintaining homeostasis.[1][2] PGI2 acts as a vasodilator and a potent inhibitor of platelet aggregation.

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.

2024年8月14日 · Prostaglandin I2 (PGI2), also known as prostacyclin, is another important prostaglandin synthesized from arachidonic acid. It is primarily produced by endothelial cells and plays a crucial role in vascular homeostasis.

Prostacyclin, or PGI (2), is an end product derived from the sequential metabolism of arachidonic acid via cyclooxygenase and PGI synthase (PGIS). The receptor for PGI (2), IP, can be found on a variety of cell types and signaling through this receptor exhibits broad physiological effects.

Continuous intravenous infusion of prostaglandin I2 (PGI2) analog, epoprostenol, has improved the survival rate for severe pulmonary hypertension, but longer treatment with PGI2 sometimes occurs hyperthyroidism.

Prostacyclin (PGI2) generated by the vascular wall is a potent vasodilator, and the most potent endogenous inhibitor of platelet aggregation so far discovered. Prostacyclin inhibits platelet aggregation by increasing cyclic AMP levels.

Prostacyclin (PGI 2) is a member of the prostaglandin family of bioactive lipids. Its best-characterized role is in the cardiovascular system, where it is released by vascular endothelial cells, serving as a potent vasodilator and inhibitor of platelet aggregation.

2024年6月21日 · PGI2 receptor agonists work by targeting and activating the prostacyclin receptor (IP receptor) on the surface of certain cells. When prostacyclin binds to its receptor, it triggers a cascade of intracellular events leading to various biological effects.

2012年7月18日 · Prostacyclin, or PGI 2, is an end product derived from the sequential metabolism of arachidonic acid via cyclooxygenase and PGI synthase (PGIS). The receptor for PGI 2, IP, can be found on a variety of cell types and signaling through this …
