膜片箝技术的问世促进了离子通道研究的飞速发展。但是消化道平滑肌细胞离子通道的研究相对滞后于神经和心肌等其它可兴奋细胞。1 离子通道的分类胃肠平滑肌细胞的离子通道有三种类型 :①电压门控通道 :电压门控的钠通道、钾通道、钙通道等 ;②配体门控通道 :乙酰胆碱受体通道
The advent of patch clamp technology has promoted the rapid development of ion channel research. However, the study of ion channel of gastrointestinal smooth muscle cells lags behind that of other excitable cells, such as nerve and myocardium. 1 Classification of ion channels There are three types of ion channels in gastrointestinal smooth muscle cells: voltage-gated channels: voltage-gated sodium channels, potassium channels, calcium channels, etc .; ② ligand gated channels: acetylcholine receptor channels
