了解视网膜神经节细胞(retinal ganglion cells,RGCs)的电生理学特性及其影响因素,有助于深入了解其正常状态下独特的生理功能,对于从细胞功能学角度阐明青光眼等视神经变性疾病的发病机制具有重要意义。本文就近年来随着膜片钳技术的应用,有关RGCs电压门控离子通道、配体门控离子通道,以及一些神经调质对这些通道的影响等方面的研究进展作一综述。
The knowledge about electrophysiological properties of retinal ganglion cells(RGCs), as well as modulation of these properties, is important not only for understanding the unique physiological functions of RGCs under normal conditions, but also for exploring the cellular mechanisms of retinal neurodegeneration diseases, such as glaucoma. In this paper, we reviewed the progress in electrophysiological studies of RGCs by using patch-clamp techniques, concerning the voltage-gated ion channels, the ligand-gated ion channels and the effects of neuromodulators on these channels.
