What is PGD2 enzyme?
An enzyme which synthesizes it, prostaglandin D2 synthase (PTGDS or lipocalin-PGDS) is hormone responsive in multiple other organs. PGD2 has two known receptors, GPR44 and PTGDR. GPR44 was found to be necessary for the decrease in hair growth by PGD2.

Does aspirin cause vasodilation?
Consistent with the unique blood pressure effect, our results reveal that salicylates, including aspirin and sodium salicylate, have a unique vasodilator action.
Do prostaglandins cause hypotension?
Prostaglandin E2 (PGE2) is a major prostanoid with a wide variety of biological activities. PGE2 can influence blood pressure (BP) both positively and negatively. In particular, centrally administered PGE2 induces hypertension whereas systemic administration of PGE2 produces a hypotensive effect.
Do prostaglandins cause bronchoconstriction?
Prostaglandin D2 (PGD2) is a potent bronchoconstrictor, and is thought to have a role in the pathogenesis of asthma.
Do prostaglandins help asthma?
Prostaglandins may also play a role in the pathogenesis and treatment of asthma. The E prostaglandins are potent bronchodilators, whereas the F compounds are bronchoconstrictors. In addition, PGE2 prevents bronchoconstriction induced by agents such as histamine, serotonin, bradykinin, and acetylcholine.
