Endothelial cells and pericytes show AD-related transcriptional changes affecting blood-brain barrier integrity, including tight junction gene downregulation (CLDN5, OCLN), altered pericyte contractile gene expression, and upregulation of adhesion molecules (VCAM1, ICAM1). However, vascular cell RNA is severely degraded by post-mortem interval, tight junction gene downregulation is a known PMI artifact, and BBB dysfunction is inconsistent across AD patients. Major confounding limits interpretabi
# Vascular-Glial Interface Restoration as a Therapeutic Target in Neurodegeneration
## Introduction and Conceptual Framework
The blood-brain barrier (BBB) represents a highly specialized interface where vascular cells—endothelial cells, pericytes, and surrounding glial populations—coordinate to maintain CNS homeostasis. This neurovascular unit (NVU) extends far beyond simple barrier function; it actively regulates cerebral blood flow, controls the clearance of metabolic waste products, and mod
