Comparing 2 hypotheses side-by-side
**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
## Mechanistic Overview Purinergic P2Y12 Inverse Agonist Therapy starts from the claim that modulating P2RY12 within the disease context of neurodegeneration can redirect a disease-relevant process. The original description reads: "**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 ad
