Aβ initiates tau missorting, but persistent degeneration is then maintained by activated microglia through C1q/C3-CR3-mediated pruning and inflammatory remodeling. This model best explains continued synapse loss after amyloid reduction, though it may maintain degeneration more clearly than tau polarity failure itself.
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.
No same-target convergence detected in this selection.
Divergent signals
No direct polarity conflicts detected among the selected hypotheses.
