**Molecular Mechanism and Rationale**
The triggering receptor expressed on myeloid cells 2 (TREM2) represents a critical microglial receptor that orchestrates the clearance of pathological protein aggregates, including extracellular tau species. TREM2 is a single-pass transmembrane glycoprotein expressed predominantly on microglia in the central nervous system, functioning as a pattern recognition receptor that detects damage-associated molecular patterns (DAMPs) and lipid ligands. The receptor
## 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
