Prostaglandin E(2) (PGE(2)) has intriguing effects on platelet function in the presence of agents that raise cyclic adenosine 3'5'-monophosphate (cAMP). PGE(2) reverses inhibition of platelet aggregation by agents that stimulate cAMP production via a G(s)-linked receptor, but adds to the inhibition of platelet function brought about by agents that raise cAMP through other mechanisms. Here, we used the EP receptor antagonists DG-041 (which acts at the EP3 receptor) and ONO-AE3-208 (which acts at… CONTINUE READING
