查询词典 postsynaptic

However, a growing number of studies suggest that excessive extracellular glutamate and resultant overstimulation of its receptors cause excitotoxic roles and lead to neuronal damage in several pathological conditions such as cerebral ischemia. Normally, the excitatory postsynaptic roles of glutamate are terminated by the activities of high-affinity sodium dependent glutamate transporters that locate on neuroglial cells and neurons near the synaptic cleft, which are thought to play important roles in inactivating released glutamate and keep it below toxic levels in the extracellular space.

在生理状态下，突触间隙中谷氨酸的清除取决于邻近神经胶质细胞及神经元上高亲和力、钠依赖性谷氨酸载体的活动，通过该载体的再摄取机制保持细胞外谷氨酸浓度于正常范围，这在预防谷氨酸的神经毒中起着重要的作用。
