## **Molecular Mechanism and Rationale**
The triggering receptor expressed on myeloid cells 2 (TREM2) represents a critical immunoreceptor that orchestrates microglial activation and survival in the central nervous system. TREM2 is a single-pass transmembrane glycoprotein belonging to the immunoglobulin superfamily, expressed exclusively on microglia within the brain parenchyma. Upon ligand binding, TREM2 associates with the DNAX-activating protein of 12 kDa (DAP12) adaptor protein through char
## 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
