Figure 7From: Cellular and temporal expression of NADPH oxidase (NOX) isotypes after brain injury Neurons were positive for NOX4 in the brain ipsilateral to the injury site. NeuN+ (green) cells were also immunolabeled with NOX4 (red) in sham-injured brains, at 24 hours and at 28 days post-injury, but not in 7 days post-injury brains. Arrows indicate double-labeled cells. Bar = 50 μm (sham and 7 days); 20 μm (24 hours).Back to article page
