Antiseizure effect of 2-deoxyglucose is not dependent on the presynaptic vacuole ATP pump or the somatic ATP-sensitive K+ channel

Abstract

Inhibition of glycolysis with 2-deoxyglucose (2-DG) represents a novel metabolic antiseizure approach, yet the mechanisms remain elusive. Here, we show that 2-DG’s antiseizure action is both glycolysis and temperature dependent but not mediated by the vacuole ATP pump (V-ATPase) or ATP-sensitive K+ channel (KATP). Our data provide new insights to understand 2-DG’s cellular mechanisms of action and, more broadly, neuronal metabolism and excitability.
