Requirement of Glycogenolysis for Uptake of Increased Extracellular K+ in Astrocytes: Potential Implications for K+ Homeostasis and Glycogen Usage in Brain

The importance of astrocytic K + uptake for extracellular K + ([K + ] e ) clearance during neuronal stimulation or pathophysiological conditions is increasingly acknowledged. It occurs by preferential stimulation of the astrocytic Na + ,K + -ATPase, which has higher K m and V max values than its neu...
