神经细胞死亡：新的杀手对神经元而言，谷氨酸扮演着双重角色。一方面，它几乎是脑内最为重要的兴奋性神经递质，介导兴奋性信号的跨膜传递；而另一方面，在中风、脑损伤及神经退行性变时，谷氨酸又可作为兴奋性毒素大量涌入神经元，造成神经元的死亡。最近，对谷氨酸兴奋... Neuronal cell death: a new killer For neurons, glutamate plays a dual role. On the one hand, it is almost the most important excitatory neurotransmitter in the brain that mediates the transmembrane transmission of excitatory signals; on the other hand, glutamate acts as a neurotrophic factor in stroke, brain injury and neurodegeneration Excitotoxin poured into neurons in large numbers, resulting in the death of neurons. Recently, excited about glutamic acid ...
