内啡肽(Endorphins)是可以充当神经递质的内源性阿片肽(1)。在锻炼、兴奋、疼痛、刺激性食物、爱和性高潮的过程中,内啡肽由脊椎动物下丘脑和脑垂体产生。类似于阿片类药物,它们可以使人产生镇痛和幸福的感觉。内啡肽具有一定的药理活性,类似于皮质类固醇类,并非特定的化学制剂。它由两部分组成:endo-和-orphin,代表了内源性和吗啡(2), β-endorphin主要有两种产生方式:从脑垂体释放到血液和从下丘脑神经元释放进入脊髓和脑。由于存在血脑屏障,释放进入血液的β-endorphin不能大量进入脑中,虽然可以在血液测定β内啡肽,但其生理意义目前尚不清楚。β-endorphin是促肾上腺皮质激素(ACTH)的前体物质POMC的裂解产物。主要通过作用于脑和脊髓发挥其行为效应,据推测,β-endorphin主要来源于下丘脑神经元。在促肾上腺皮质激素(ACTH)水平升高的情况下(例如,库欣综合征),β-endorphin的水平也略有增加(3)。
