Fig. 5From: Ginsenoside Re protects methamphetamine-induced dopaminergic neurotoxicity in mice via upregulation of dynorphin-mediated κ-opioid receptor and downregulation of substance P-mediated neurokinin 1 receptorMA-induced changes in substance P-immunodistribution. Substance P-immunoreactivity was localized in the NeuN-labeled neurons (a), GFAP-labeled astrocytes (b), and Iba-1-labeled microglial cells (c). Arrow indicates co-localization.
