Upon autophagy induction, neurons uniquely accumulate p62/SQSTM1 due to inefficient recognition of polyubiquitinated aggregates, creating an mTORC1-activating domain (MAZ)-mediated feedback loop that terminates the autophagic response prematurely. This hypothesis was substantially weakened by SKEPTIC critique due to mechanistic non-uniqueness and lack of demonstrated neuronal specificity in the p62 accumulation response compared to other cell types.
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
