Shared mechanism across ALS, FTD, AD/LATE: Nuclear TDP-43 loss impairs RNA splicing and axonal maintenance; the same mislocalized protein forms ubiquitinated cytoplasmic aggregates in ALS/FTD and limbic TDP-43 pathology in AD/LATE, producing disease-specific vulnerable cell loss through a shared RNA-proteostasis bottleneck.
Falsifiable prediction: Restoring nuclear TDP-43 localization in TARDBP iPSC motor neurons and AD/LATE hippocampal neurons should normalize STMN2-like splicing markers and r
Shared mechanism across PD, DLB, MSA: SNCA mutations and alpha-synuclein inclusions define neuronal Lewy pathology in PD/DLB, while MSA shows oligodendroglial alpha-synuclein inclusions. A shared misfolded-alpha-synuclein seeding axis likely diverges by host cell proteostasis and lipid environment, explaining overlapping proteinopathy with distinct anatomy.
Falsifiable prediction: Patient-derived alpha-synuclein seeds from PD/DLB and MSA should induce different neuronal-versus-oligodendroglial
