CUMS induced M1 marker iNOS expression in the prefrontal cortex and hippocampus of both adolescent and adult rats, while minocycline treatment reduced the expression. (A) iNOS expression in the prefrontal cortex and hippocampus in immunohistochemistry (× 400); (B) iNOS-positive cell counts in the prefrontal cortex; (C) iNOS-positive cell counts in the hippocampus; (D) Western blot analysis of iNOS in the prefrontal cortex; (E) Western blot analysis of iNOS in the hippocampus. Results are expressed as the mean ± SEM (n = 4 each group; n = 5 each group). #, ##, and ### indicate p < 0.05, p < 0.01, and p < 0.001 vs. C group, respectively; *, **, and *** indicate p < 0.05, p < 0.01, and p < 0.001 vs. S group, respectively. AdoC, adolescent control group; AdoS, adolescent CUMS group; AdoS+M, adolescent CUMS and minocycline group; AduC, adult control group; AduS, adult CUMS group; AduS+M, adult CUMS and minocycline group.
