**Molecular Mechanism and Rationale**
The TREM2 (Triggering Receptor Expressed on Myeloid cells 2) signaling cascade represents a critical convergence point where microglial phagocytic responses intersect with neuronal mitochondrial quality control mechanisms. TREM2, a transmembrane glycoprotein predominantly expressed on microglia and macrophages, functions as a damage-associated molecular pattern (DAMP) receptor that recognizes phosphatidylserine (PS) exposed on damaged cellular membranes, in
## 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
