KEAP1 and Parkinson disease: Emerging evidence also suggests that inhibiting Keap1 can ameliorate neuronal degeneration, with Keap1 RNA interference (RNAi) protecting against Aβ42[30] and MPTP[31] toxicity in cells, and heterozygous loss of Keap1 protecting against neuronal pathology in Drosophila models of PD[32,33].
