Ukgansan Protects Dopaminergic Neurons against MPTP-Induced Neurotoxicity via the Nurr1 Signaling Pathway
Figure 3
Protective effect of Ukgansan on dopaminergic neurons in differentiated PC12 cells. Dopaminergic neurons were visualized with TH-immunohistochemistry. Representative photomicrographs were taken of SNpc and ST (a) Effect of Ukgansan on changes of neurotransmitter levels in the striatum. ST was dissociated and lysed to measure the dopamine using ELISA kits 7 days after the last MPTP injection (b) Numbers of TH-positive neurons in the SNpc were counted or TH protein levels, and the optical density and TH protein levels in the ST were measured ((c) and (d)). Values are indicated as the mean ± S.E.M. compared with the control group, ## and ### compared with the MPTP-only treated group.
