TDP-43 aggregates sequester hepatocyte growth factor-regulated tyrosine kinase substrate (HGS), a critical hub coordinating early endosome-to-autophagosome cargo delivery. In motor neurons where TDP-43 nuclear loss and cytoplasmic aggregation occurs early in ALS, HGS is functionally depleted, creating specific vulnerability where upstream autophagy induction cannot compensate for downstream cargo recognition failure. This hypothesis survived critique due to its mechanistic specificity for motor
Neurons express a distinct V-ATPase subunit isoform profile (ATP6V0C splice variants and ATP6V1G2 enrichment) resulting in slower lysosomal acidification kinetics and defective lysosomal transport along microtubules. This creates a bottleneck where fusion-competent autophanosomes cannot efficiently intersect with properly acidified lysosomes, misinterpreted as 'autophagy resistance'. This hypothesis survived SKEPTIC critique with intact mechanistic specificity and was prioritized by DOMAIN_EXPER
