摘要: 前列腺素 D2 (PGD2)是由前列腺素 D2 合成酶合成的一种二十碳不饱和脂肪酸。研究表明PGD2 具有睡眠调节作用,其机理为 PGD2 与前列腺素D2 受体结合,升高基底前脑部位细胞外腺苷水平。腺苷通过腺苷 A2A 受体激活睡眠调节中枢(腹外侧视前区,VLPO)神经元,并通过 GABA 抑制觉醒调节中枢(结节乳头核,TMN)组胺能神经元而导致睡眠。对 PGD2睡眠调节作用及其机理进行研究,有望开发出新型的镇静催眠药物。

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
