**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-Dependent Astrocyte-Microglia Cross-talk 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 (Triggering Receptor Expressed on Myeloid cells 2) signaling cascade represents a critical node in neuroinflammation regulation, with its dysfunction fundamentally altering astrocyte-microgli
