摘要 谷氨酸转运体EAAT2(啮齿类动物命名为GLT-1:谷氨酸转运体1)是海马和前额叶星形胶质细胞上一种非常重要的谷氨酸转运体,其承担了细胞外大部分谷氨酸的摄取和转运,由于谷氨酸转运体EAAT2的作用在于降低突触间隙过高的谷氨酸水平,避免过高浓度的谷氨酸对神经元和神经胶质细胞的兴奋毒性作用,使之逐渐成为近年来抑郁症研究的热点。该文主要就谷氨酸转运体EAAT2在抑郁症中可能的病理生理作用,以及其可能作为新一代抗抑郁药作用的靶点进行综述。 The glutamate transporter EAAT 2 ( rodent nomencla-ture GLT-1:glutamate transporter 1), which is a predominantly astroglial glutamate transporter in the hippocampus and the pre-frontal cortex , is responsible for the majority of extracellular glu-tamate uptake .The glutamate transporter EAAT 2 can decrease the high levels of glutamate in the synaptic cleft , avoiding gluta-matergic excitotoxicity to damage the glial cells and neurons . Currently, the transporter EAAT2 has become a research hotspot of depression .This article aims to summarize roles of glutamate transporter EAAT2 in the occurrence and treatment of depres-sion.
