**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
The activity-dependent trafficking of complement regulators CD55 and CD46 to synaptic surfaces represents a dynamic regulatory mechanism controlling complement-mediated synaptic pruning through vesicular transport and membrane insertion. Rather than static differential expression, CD55 and CD46 undergo rapid, activity-dependent translocation from intracellular vesicular pools to synaptic membranes via SNARE-mediated exocytosis. High-frequency synaptic activity triggers calcium influx through NMD
