Our own evidence suggests that increased Mic60 availability in dopaminergic cells is protective against PD-relevant stressors in vitro, and Tsai et al. demonstrated that Mic60 overexpression can rescue PD phenotypes in vivo in PINK1-mutant Drosophila (Van Laar et al., 2016; Tsai et al., 2018). This evidence concerns the gene PINK1 and Parkinson disease.
