**Molecular Mechanism and Rationale**
The P2RY12-mediated autophagy inhibition hypothesis centers on the purinergic receptor P2RY12, a G-protein coupled receptor (GPCR) that responds to adenosine diphosphate (ADP) and plays critical roles in platelet aggregation and microglial activation. In cerebral vascular smooth muscle cells (VSMCs), P2RY12 activation triggers a downstream signaling cascade that fundamentally disrupts the cellular autophagy machinery responsible for amyloid-β (Aβ) clearance
**Molecular Mechanism and Rationale**
The purinergic receptor P2RY12, traditionally recognized for its critical role in platelet aggregation and microglial activation, has emerged as a potential mediator of neurovascular dysfunction through its expression in cerebral vascular smooth muscle cells (VSMCs). This hypothesis proposes that sustained P2RY12 activation in cerebral arterial VSMCs disrupts autophagy flux through mTOR pathway engagement, ultimately compromising blood-brain barrier (BBB) i
