摘要
超极化激活环核苷酸门控阳离子通(hyperpolarization-activated cyclic nucleotide-gated channel,HCN channel)广泛表达于中枢和周围神经系统,通过其介导的超极化激活阳离子电流(hyperpolarization-activated cation current,Ih)调节神经元的静息膜电位和兴奋性来影响听觉的精确加工和传导,对时间信息的精确分析起着至关重要的作用.因此,本文通过对HCN通道结构和分布以及电生理作用进行综述,进一步探讨HCN通道在正常及单侧聋或双侧聋情况下听觉传导通路中的作用及机制.
Abstract
Hyperpolarization-activated cyclic nucleotide-gated(HCN)channels are widely expressed in the central and peripheral nervous systems.They can generate hyperpolarization-activated current(Ih)that regulates the resting membrane potential and excitability of neurons.Furthermore,it can affect the precise processing and con-duction of hearing,which plays a crucial role in the accurate analysis of temporal information.Therefore,through the review of HCN channel structure and distribution,as well as electrophysiological effects,the role and mecha-nism of HCN channels in the auditory pathways of the normal and unilateral or bilateral deafness patients will be fur-ther investigated.
