Aspirin modulates production of pro-inflammatory and pro-resolving mediators in endothelial cells.

ABSTRACT: Endothelial cells synthesize biochemical signals to coordinate a response to insults, resolve inflammation and restore barrier integrity. Vascular cells release a variety of vasoactive bioactive lipid metabolites during the inflammatory response and produce pro-resolving mediators (e.g., Lipoxin A4, LXA4) in cooperation with leukocytes and platelets to bring a halt to inflammation. Aspirin, used in a variety of cardiovascular and pro-thrombotic disorders (e.g., atherosclerosis, angina, preeclampsia), potently inhibits proinflammatory eicosanoid formation. Moreover, aspirin stimulates the synthesis of pro-resolving lipid mediators (SPM), so-called Aspirin-Triggered Lipoxins (ATL). We demonstrate that cytokines stimulated a time- and dose-dependent increase in PGI2 (6-ketoPGF1α) and PGE2 for
