Aβ initially perturbs tau localization, but persistence depends on BIN1-regulated membrane and endocytic trafficking that prevents tau re-entry into the axon and stabilizes dendritic retention. This is a useful genetic-modifier hypothesis, but currently the least supported as a primary mechanism.
Transient Aβ exposure induces dendritic tau missorting that then converts into a locally self-propagating tau oligomer/seeding program. After verified Aβ clearance, continued degeneration is driven by tau seed formation, templated misfolding, and trans-synaptic spread rather than by ongoing amyloid signaling.
