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.
## Mechanistic Overview
TREM2-Dependent Astrocyte-Microglia Cross-talk in Neurodegeneration starts from the claim that modulating TREM2 within the disease context of neurodegeneration can redirect a disease-relevant process. The original description reads: "## **Molecular Mechanism and Rationale** The TREM2 (Triggering Receptor Expressed on Myeloid cells 2) signaling cascade represents a critical node in neuroinflammation regulation, with its dysfunction fundamentally altering astrocyte-microgli

Most investable survivors are `6 > 4 > 1 > 2`. I would not spend serious translational budget yet on `7`, and I would treat `3` and `5` as modifier mechanisms rather than lead programs.
