# 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, comprised of endothelial cells, pericytes, smooth muscle cells (collectively termed vascular mural cells), astrocytes, and neurons. This hypothesis posits that progressive degeneration of vascular mural cells—specifically pericytes and vascular smooth muscle cells (VSMCs)—consti
## **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 drainage through the glymphatic system. In neurodegenerative diseases, pericyte dysfunction manifests as loss of contractile tone, altered perivascular space dimensions, and compromised vascular integrity. The platelet-derived growth factor receptor-β (
