摘　　要：内源性大麻素系统在脊椎动物视网膜中广泛分布。大麻素受体(cannbinoid receptor)主要有CB1和CB2两个亚型,与内源性配体N-花生四烯酸氨基乙醇(N-arachidonoylethanolamide,anandamine,AEA)和2-花生四烯酸甘油(2-arachidonyl glycerol,2-AG)结合调控视网膜神经元和胶质细胞的功能,从而参与调控视网膜视觉信息的处理。本文结合我们研究组近年在视网膜大麻素受体系统的研究结果,综述了有关大麻素CB1和CB2受体对视网膜细胞离子通道和突触传递调控及其机制的研究进展。Endocannabinoid receptor system is extensively expressed in the vertebrate retina. There are two types of cannabinoid receptors, CB1 and CB2. Activation of these two receptors by endocannabinoids N-arachidonoylethanolamide （anandamine, AEA） and 2-arachidonyl glycerol （2-AG） regulates multiple neuronal and glial ion channels, thus getting involved in retinal visual information processing. In this review, incorporating our results, we discuss the modulation of cannabinoid CB1 and CB2 receptors on retinal neuronal and glial ion channels and retinal synaptic transmission.
