缩胆囊素在神经系统中的作用

Effect of Cholecystokinine on Nervous System

目的总结缩胆囊素(cholecystokinine,CCK)的生物学特性及其在中枢神经系统中的生物学作用。方法通过检索近年来相关文献,分析总结关于CCK作为神经肽/神经递质在信号传递、神经保护及镇痛等方面的研究进展。结果CCK作为神经递质能够拮抗致痫剂的致痫作用;CCK8还能够对抗神经元的手术和化学损伤以及延缓神经元老化;CCK在痛觉传导过程中起到了重要的整合作用。结论CCK是大脑中最丰富的神经递质/神经肽之一,同时也是中枢和外周神经系统中一重要的信号因子,在神经系统中有着非常重要的生物学作用。

Objective To review the biologic characteristics and biologic effect of cholecystokinine （CCK） on the central nervous system. Methods The literatures of recent years on research advancement of cholecystokinine as neurotransmitters/peptides in signal transduction, neuron protection and pain management in the central nervous system are reviewed. Results CCK possesses the ability to suppress the convulsant effects of convulsants. CCK8 is able to reduce the neural damage caused and delay the neural aging. CCK antagonists play an important role in human pain transduction. Conclusion CCK has been proven to be one of the richest neurotransmitters/neuropeptides as well as an important signal factor in the brain, and its important biologic effect is being confirmed.
