Shared mechanism across ALS, FTD, PD: TBK1 coordinates selective autophagy adaptors and innate immune tone. TBK1 haploinsufficiency causes ALS/FTD, while the same PINK1/Parkin/TBK1-adjacent mitochondrial quality-control network constrains PD-like mitochondrial and alpha-synuclein stress.
Falsifiable prediction: Partial TBK1 restoration should increase phospho-OPTN recruitment and reduce p62/TDP-43 aggregate load in ALS/FTD neurons; in PD dopaminergic neurons it should improve damaged-mitochondr
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
