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
Impaired autophagic flux and lysosomal degradation capacity represents a convergent failure point across AD, PD, ALS, and FTD. Multiple druggable nodes exist: TFEB activation, GBA1 enhancement, TMEM175 modulation, and VPS35/retromer stabilization. Cross-disease genetic evidence (GBA1, VPS35, TMEM175, SORL1) and postmortem tissue validation support this mechanism. Best near-term path is biomarker-enriched trials in GBA1-PD or prodromal carriers. CNS druggability remains the primary development ba
