MLKL and Parkinson disease: This study revealed more pMLKL+/TH+ and pMLKL+/Ub+ cells measured through histological data, and higher ubiquitylated pMLKL levels measured using co-immunoprecipitation assay in MPTP-intoxicated SN than in the control group, and the reversal effects of NSA exposure implied that repeated treatment with NSA hinders the cell death-inducing activity of MLKL in PD mice.
