NDI1 can maintain normal morphology and survival of neurons in SN of MPTP-induced PD mouse model. A: The morphology of neurons in SN (scale bar: 50 μm). B: Tyrosine hydroxylase (TH)-positive surviving neurons in SNpc (indicated by black circle) and ventral tegmental area (VTA) (scale bar: 500 μm). C, D: Statistical analysis of surviving number of neurons in VTA and SNpc. ns: no significant difference, *: P < 0.05, ***: P < 0.001
