## Mechanistic Overview
Vascular and Perivascular Cell Type Vulnerability: BBB Integrity Disruption starts from the claim that modulating CLDN5 within the disease context of neurodegeneration can redirect a disease-relevant process. The original description reads: "## Mechanistic Overview Vascular and Perivascular Cell Type Vulnerability: BBB Integrity Disruption starts from the claim that modulating CLDN5 within the disease context of neurodegeneration can redirect a disease-relevant process. T
Gut dysbiosis-driven butyrate deficit causes HDAC-mediated silencing of CLDN5 in brain endothelial cells; tributyrin prodrug restores CLDN5 expression via H3K27ac enrichment at the CLDN5 promoter, re-sealing the BBB in a virtuous cycle linking gut microbiome to neurovascular integrity.
