The Impact of Paeoniflorin on α-Synuclein Degradation Pathway

Figure 4

Change in proteasome activity following MPP+ and PF treatment. Under normal circumstances, the impact of PF on proteasome activity was not statistically significant (). MPP+ inhibited the ubiquitin-proteasome activity (). Paeoniflorin reversed the decline of proteasome activity caused by MPP+ () ( MPP+ group versus control group; versus MPP+ group; mean ± SD, ).
