**Molecular Mechanism and Rationale**
The P2Y12 purinergic receptor represents a critical molecular determinant of microglial territorial organization and synaptic surveillance within the central nervous system. P2Y12, encoded by the P2RY12 gene, functions as a Gi/Go-coupled metabotropic receptor that exhibits exquisite sensitivity to extracellular nucleotides, particularly ADP and ATP. Under physiological conditions, active synapses release ATP through pannexin-1 channels and vesicular nucleot
**Molecular Mechanism and Rationale**
The differential expression of complement regulators CD55 (decay-accelerating factor, DAF) and CD46 (membrane cofactor protein, MCP) on synaptic membranes represents a sophisticated molecular mechanism for spatial regulation of complement-mediated synaptic pruning. CD55 functions as a membrane-bound glycoprotein that accelerates the decay of both classical and alternative pathway C3 and C5 convertases (C4b2a, C3bBb, and C3b2Bb) by dissociating the enzymatic
