Nitrotyrosine levels are significantly different among groups in the ventral midbrain (F_(3,23) = 4.56;p < 0.05) but not in cerebellum (F_(3,23) = 0.618; p > 0.05).

↵* p < 0.05, more than saline-injected and minocycline-injected control mice.

↵F1-160 p < 0.05, less than MPTP-injected mice but not different from both control groups. Saline, Mice injected with saline; Minocycline, mice injected with minocycline only (45 mg/kg twice daily); MPTP, mice injected with MPTP only (18 mg/kg MPTP for 4 injections in one day); MPTP–minocycline, mice injected with both MPTP and minocycline. Values are means ± SEM (n = 6–8 per group).
