The debate supports carrying forward microglial priming as a partially upstream causal node rather than a pure disease-stage correlate only if a proximal endpoint changes before the late outcome. The decisive validation path is: triangulate cell-type-specific MR, scVelo trajectory direction, and longitudinal CSF cytokine Granger causality with disease-specific sensitivity analyses.
## 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
