Prostaglandins and inflammation. (a) Prostaglandin E2 (PGE2) stimulation of inflammatory response. Numbers indicate the sequence of events from PGE2 synthesis to stimulation of inflammation trough positive feedback on cyclooxygenase (COX)-2 and negative feedback on microsomal PGE synthase-1 (mPTGES-1); (b) The anti-inflammatory role of prostaglandin J2 (PGJ2); (c) prostaglandin F2α (PGF2α) signaling; (d) prostaglandin I2 (PGI2) signaling.
