Endosomal escape is the critical intracellular bottleneck for propagation
🧪 Overview
Mechanistic rationale: Following endocytosis, tau seeds must escape from endosomes to the cytoplasm where they can template endogenous tau. I propose that endosomal acidification and vacuolar ATPase activity are the key determinants of propagation efficiency. Acidic endosomes allow proteolytic processing of tau that exposes cryptic seeding domains; proton pump inhibition blocks propagation in vitro.
Debate provenance: derived from debate `sess_SDA-2026-04-04-gap-tau-prop-20260402003221` on question: Tau propagation mechanisms and therapeutic interception points. Consensus signal: domain_expert, skeptic, theorist discussed the mechanism terms Endosomal, bottleneck, critical, escape, inhibition, intracellular, propagation. Novelty signal: skeptic-discussed-with-qualified-concession.
