Mislocalized tau impairs dendritic endosome-lysosome and autophagy flux, trapping tau species in the somatodendritic compartment and sustaining synaptotoxic signaling after Aβ has been removed. This is best viewed as a persistence amplifier rather than the leading initiating 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.
Convergent vs Divergent Predictions
This summary checks where the selected hypotheses point toward the same target or mechanism, and where they pull in opposite directions.
MAPT recurs across 2 selected hypotheses with aligned directionality in autophagy lysosome, protein aggregation.
