Prostaglandins and chronic inflammation

Prostaglandins and inflammation.

Prostaglandins are lipid autacoids derived from arachidonic acid. They both sustain homeostatic functions and mediate pathogenic mechanisms, including the inflammatory response. They are generated from arachidonate by the action of cyclooxygenase isoenzymes, and their biosynthesis is blocked by nonsteroidal antiinflammatory drugs, including those selective for inhibition of cyclooxygenase-2.

Prostaglandins and inflammation: the cyclooxygenase controversy.

Prostaglandins (PGs) are arachidonic acid metabolites produced by the action of the enzyme cyclooxygenase (COX). Although PGs are important mediators of inflammation in various diseases, they also are key factors in the physiological regulation of gastrointestinal and renal homeostasis. The finding that two distinct COX isoforms are responsible for PG synthesis has provided basis to the opposit...

The effect of intravitreal and topical prostaglandins on intraocular inflammation.

We investigated the effects of prostaglandins (PG) E2, PGD2, PGI2, and its metabolites 6-keto-PGE1 and 6-keto-PGF1 alpha, and U46619 (stable analogue of the PG endoperoxide, PGH2) administered either intravitreally or topically on intraocular pressure (IOP), pupil diameter, aqueous protein, and the entry of polymorphonuclear cells (PMNs) in the aqueous. PGE2, 6-keto-PGE1, U46619, and PGI2 incre...
