Site-specific TREM2 cleavage fragments (N-terminal vs C-terminal ratios) serve as the primary readout for microglial priming state, with CHI3L1 (YKL-40) and neurogranin as confirmatory cascade markers that validate the temporal sequence of neuroinflammation. The mechanistic foundation centers on ADAM10/17-mediated TREM2 shedding as the proximal event that defines microglial transition from homeostatic surveillance to priming phase. This transition triggers downstream CHI3L1 expression and synapt
## Mechanistic Overview
H1: TREM2 Agonism to Redirect APOE4-Enhanced Microglia from Synapse Pruning to Amyloid Clearance starts from the claim that modulating TREM2 within the disease context of neurodegeneration can redirect a disease-relevant process. The original description reads: "Background and Rationale Alzheimer's disease (AD) represents the most common cause of dementia worldwide, yet therapeutic strategies targeting amyloid-β have shown limited clinical efficacy, highlighting the need
