Comparing 2 hypotheses side-by-side
Sustained P2RY12 activation in cerebral arterial VSMCs inhibits autophagy flux via mTOR pathway engagement, leading to accumulation of damaged organelles and protein aggregates within the vascular wall. This compromises neurovascular unit integrity, resulting in BBB leakage, pericyte detachment, and downstream neuronal toxicity from plasma protein infiltration. Plausible mechanistic extension of the P2RY12-autophagy axis, but BBB integrity is dominated by endothelial tight junctions, pericytes,
**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
