**Molecular Mechanism and Rationale**
The P2Y12 receptor, encoded by the P2RY12 gene, represents a critical component of microglial surveillance and activation machinery in the central nervous system. This Gi/Go-coupled purinergic receptor responds to extracellular adenosine diphosphate (ADP) and adenosine triphosphate (ATP) released from neurons and other glial cells. Under physiological conditions, P2Y12 receptors maintain microglial processes in a dynamic, highly motile state that enables co
**Molecular Mechanism and Rationale**
The P2Y12 receptor (encoded by P2RY12) represents a critical nexus in microglial purinergic signaling that governs neuroinflammatory responses and tau pathology propagation in neurodegenerative diseases. P2Y12 is a Gi/Go-coupled metabotropic purinergic receptor that serves as the primary ADP sensor on microglial cells, functioning as a molecular switch between homeostatic surveillance and pathological activation states. Under physiological conditions, P2Y12
