Astrocyte-specific deletion of Kir6.1/K-ATP channel aggravates cerebral ischemia/reperfusion injury through endoplasmic reticulum stress in mice.

ATP-sensitive potassium (K-ATP) channels, coupling cell metabolism to cell membrane potential, are involved in brain diseases including stroke. Emerging evidence shows that astrocytes play important roles in the pathophysiology of cerebral ischemia. Kir6.
