日本生理学研究所久保义弘教授近日发现,大脑内与记忆相关的关键神经传导物质谷氨酸与受体结合时,通过使受体细胞内的蛋白质位置发生变化来传导记忆信号。此前科学家已经知道,这一受体在和谷氨酸结合时,受体细胞外部会产生结构变化,但内部结构如何变化一直是个谜。研究人员在实验中给受体细胞内蛋白质加上萤光物质,用激光照射的方法 Japan Institute of Physiology, Professor Kubo Yoshinobu recently discovered that the brain and memory-related key neurotransmitter glutamate and receptor binding, the receptor cells by changing the location of the protein to transmit the memory signal. Previously scientists have learned that this receptor and glutamate binding, the receptor cells will have a structural change outside, but how the internal structure has changed is a mystery. Researchers in the experiment to the receptor cell protein plus fluorescent substances, using laser irradiation method
