TREM2 signaling controls the spatial distribution of complement regulators CD55 and CD46 on synaptic membranes, determining which synapses are vulnerable to complement-mediated pruning. Under normal conditions, TREM2 activation promotes the expression and clustering of CD55/CD46 at perisomatic inhibitory synapses through DAM pathway signaling, while maintaining low regulator density at distal excitatory synapses. This creates a protective gradient where inhibitory circuits are preserved while al
## 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
