Purinergic P2Y12 Inverse Agonist Therapy

**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...
