Comparing 2 hypotheses side-by-side
## Mechanistic Overview Pericyte Contractility Reset via Selective PDGFR-β Agonism starts from the claim that modulating PDGFRB within the disease context of neurodegeneration can redirect a disease-relevant process. The original description reads: "## **Molecular Mechanism and Rationale** Pericytes are contractile cells that wrap around capillaries and play a crucial role in maintaining blood-brain barrier (BBB) integrity, regulating cerebral blood flow, and facilitating interstitial fluid drai
## Mechanistic Overview Vascular mural cell degeneration precedes and exacerbates parenchymal pathology starts from the claim that modulating PDGFRB within the disease context of Alzheimer's disease can redirect a disease-relevant process. The original description reads: "# Vascular mural cell degeneration precedes and exacerbates parenchymal pathology ## Overview The neurovascular unit represents a complex, integrated system essential for maintaining central nervous system homeostasis, comprise
