Luteolin reduced hippocampal neuroinflammation through PPARγ in MCAO/R treated rats. The GFAP (A) and Iba-1 (B) expression levels in damaged CA1 hippocampal region were observed using immunofluorescence, Scar bar = 20 μm. The mean gray value counted through Image J software. Vs. sham group, ^**p < 0.01; Vs. vehicle group, ^##p < 0.01; Vs. luteolin-25 group, ^&p < 0.05, ^&&p < 0.01; Vs. luteolin-50 group, ^{^^}p < 0.01
