Western blot analysis of microglia/astroglial markers in rat brain 2, 8 and 12 weeks after surgery. Western blot analysis of Iba1 and GFAP (Aa) 2 weeks, (Ab) 8 weeks, and (Ac) 12 weeks after surgery. Integrated density histograms of Iba1 and GFAP after 2, 8 and 12 weeks (Ba–c), respectively. β-Actin was used as an internal control. The characters a, b, and c indicate significant differences (p < 0.05) among the SNI groups. SHAM OP represents the normal control.
