摘要 多巴胺( DA)作为一种重要的儿茶酚胺类神经递质,经中脑腹侧被盖核区投射到前额叶皮质、海马、纹状体、伏隔核、杏仁核、中脑、下丘脑、延髓等部位的多巴胺受体( DAR),主要参与情感思维、运动功能以及认知活动,也参与突触可塑性的调控。广泛分布于各个脑区的 DAR 属于 G 蛋白偶联受体( GPCR)中的重要一员,根据其药理学和生化特性不同,可以分为D1样受体和D2样受体两大类,其中前者包括D1和D5受体2种亚型,后者受体包括D2、D3和D43种亚型。近几年研究发现DAR与中枢神经系统疾病如阿尔茨海默病( AD)关系密切,已经成为预防和治疗AD的重要靶点,然而,DAR的各个亚型在AD发病机制中的作用还不清楚,本文就DAR各个亚型的分布、信号传导及其与 AD 的发病机制的关系进行综述。
