Mechanisms underlying the PNU-282987-mediated regulation of the immune balance in the PD rat model. The differences in the expression of the α7nAChRs, p-Erk/Erk and Foxp3 proteins among the three groups were determined using Western blotting. β-actin was used as a loading control to ensure equal protein loading. +p < 0.05 compared with the 6-OHDA-lesion group (n = 6 per group), and *p < 0.05 compared with the 6-OHDA-lesion + sham group (n = 6 per group).
