SCI induces upregulation of NOX2 expression predominantly in microglia/macrophages. (A-B) NOX2 elevation in injured spinal cord tissue. n=3–6 mice/group. *p<0.05, ***p<0.001 vs Sham. (C) At 24h after SCI, NOX2 expression by Iba-1+ microglia/macrophages at the lesion core. Scale bar = 25 μm. (D) NOX2+/Iba-1+ cells are significantly increased (3 fold) at the lesion site from 8 weeks SCI mice. N=5 mice/group. **p<0.01 vs Sham. (E) Representative images for NOX2+/Iba-1+ cells in the dorsal white matter at 0.2 mm rostral to the epicenter from Sham and 8 weeks SCI mice. Scale bar = 50 μm. Insets display high magnification images.
