The debate supports carrying forward TREM2 enhancement as a way to restore protective microglial response and reduce downstream tau spread only if a proximal endpoint changes before the late outcome. The decisive validation path is: stage-stratified TREM2 gain-of-function perturbation with microglial lipid handling, plaque compaction, and tau propagation endpoints.
## Mechanistic Overview
TREM2-Mediated Astrocyte-Microglia Crosstalk 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-mediated astrocyte-microglia crosstalk hypothesis centers on the disruption of critical intercellular communication networks that maintain brain homeostasis. TREM2 (Triggering Receptor Expressed o
