Fig. 4From: Inhibition of Astrocyte Glutamate Uptake by Reactive Oxygen Species: Role of Antioxidant Enzymes Hydrogen peroxide-induced inhibition of Glu uptake: effect of reagents inducing a decrease in cellular glutathione Various concentrations of hydrogen peroxide were added either alone (●) or in the presence of 500 µM BSO (○) or 100 µM DEM (◻). BSO and DEM were added 18 hr before incubation with 3H-Glu.Back to article page
