WebMay 11, 2024 · Previous studies have demonstrated that in vivo treatment with the PD toxin MPTP causes microglial activation [16, 30]. Therefore, we examined the response of our regionally isolated microglia to the active metabolite of MPTP, MPP + , to determine whether regionality results in differential activation profiles.
