Neurons uniquely express the PP2A Bβ1 regulatory subunit forming a phosphatase complex that selectively dephosphorylates and activates ULK1 at Ser757 but not Ser317, creating a dominant-negative ULK1 activation state refractory to most autophagy induction strategies. SKEPTIC critique weakened this by noting PPP2R2B is 'neuron-enriched' not 'neuron-exclusive', and the selective dephosphorylation specificity lacks structural validation. DOMAIN_EXPERT identifies this as high-risk requiring structur
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
