Shared mechanism across PD, AD, ALS: Mitochondrial damage normally recruits PINK1/Parkin quality control; failure of this pathway increases mtDNA leakage, oxidative stress, and aggregate toxicity. PD is genetically anchored in the pathway, AD models improve when mitophagy is restored, and ALS models show PINK1/Parkin-dependent rescue of proteotoxic stress.
Falsifiable prediction: Enhancing PINK1/Parkin-dependent mitophagy should lower mitochondrial ROS and aggregate burden by at least 20% in PD dopaminergic, AD amyloid/tau, and ALS motor-neuron models, but the effect should disappear after PARK2 knockout.
Proposed experiment: Run parallel iPSC neuron assays with PINK1/Parkin activator, PARK2 knockout, and rescue arms; quantify mitophagy reporters, mtDNA-cGAS-STING activation, ROS, alpha-synuclein/tau/TDP-43 aggregate burden, and cell survival.
Cross-disease confidence rationale: Pathway is causal in PD and experimentally rescuable in AD/ALS models.
