## Molecular Mechanism
The microglial TREM2-complement axis represents a fundamental regulatory network controlling neuroinflammation and synaptic homeostasis in neurodegenerative diseases. TREM2 (Triggering Receptor Expressed on Myeloid cells 2) is a type I transmembrane glycoprotein exclusively expressed on microglia within the central nervous system, functioning as a critical immunoreceptor that orchestrates microglial activation, survival, and phagocytic responses. The extracellular immunog
## 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
