Abstract: Prostaglandin (PG)D2 is one of unsatur-ated fatty acids with 20 carbon atoms,which is synthe-sized by PGD synthase (PGDS)in the brain.PGD2 has been identified to be a sleep-inducing substance that be-comes bound to the DPreceptor(DPR)exclusively local-ized on the surface of the basal forebrain,leading to an increase in extracellularadenosine levels there.Through A2A receptors (A2A R),the adenosine activates neurons in the ventrolateral preoptic area (VLPO),a putative sleePcenter,and inhibits neurons in the histaminergic tube-romammillary nucleus (TMN),a putative wake center,via GABA to induce sleep.Studying the effect and the molecularmechanismsof sleep-induced by PGD2 would be helpful in the development of novel sleeping drugs formore rational treatment of sleePdisorders.

Key words: PGD2, sleep, PGD synthase, DPre-ceptor, Adenosine, A 2A receptor, histamine
