Figure 2From: Cellular and temporal expression of NADPH oxidase (NOX) isotypes after brain injury Microglia were positive for NOX2 ipsilateral to the injury site. Microglia were labeled with CD11b (green) and immunostained with an antibody against NOX2 (red) in sham-injured tissue and at 24 hours, 7 days, and 28 days post-injury. Co-labeled cells are indicated with arrows. NOX2+ cells increased by 24 hours post-injury and increased further by 7 days post-injury, but by 28 days post-injury staining resembled sham. Bar = 20 μm (A, B, D); 50 μm (C).Back to article page
