Abstract:
Stimulation of astroglial glucose utilization by the Na(+)/H(+) exchanger monensin is only partially blocked by ouabain. The present studies show that monensin also raises intracellular pH in astroglia. Because increased pH stimulates phosphofructokinase activity, the ouabain-insensitive portion of the stimulation of cerebral glucose utilization (CMR(glc)) appears to be due to stimulation of glycolysis by intracellular alkalinization.
