PGI₂as a Regulator of Inflammatory Diseases

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. Historically, PGI(2) has been understood to play a role in cardiovascular health, specifically having powerful vasodilatory effects via relaxation of smooth...
