K^+通道维持着血管平滑肌细胞的静息膜电位。目前发现血管微动脉平滑肌细胞上主要表达内向整流型K^+通道、ATP敏感型K^+通道、电压依赖型K^+通道和大电导钙激活型K^+通道等四种K^+通道。本文对微动脉平滑肌细胞K^+通道最新进展做一综述。
K^+ channels contribute to the regulation of the resting membrane potential in smooth muscle cells. Four distinct types of K^+ channels have been identified in vascular smooth muscle: inward rectifier K^+ channels, ATP-sensitive K^+ channels, voltage-gated K^+ channels, and big conductance Ca^2+-activated K^+ channels. This article reviewed recent advance on potassium channels in the peripheral microcirculation.
