A human blood-brain barrier model reveals pericytes as critical regulators of viral neuroinvasion.

ABSTRACT: The blood-brain barrier (BBB) plays a vital role in regulating the passage of biomolecules between the bloodstream and the central nervous system (CNS) while also protecting the CNS from pathogens. Pericytes reside at the interface between endothelial cells and the brain parenchyma. These cells are critical for maintaining BBB integrity and regulating vessel permeability, blood flow, and immune cell migration. In this study, we developed a serum-free protocol to generate neural crest cell-derived pericytes (NCC-PCs) from human pluripotent stem cells (hPSCs). These NCC-PCs can be co-cultured with hPSC-derived brain microvascular endothelial cells (BMECs) in a co-culture BBB model that recapitulates the in vivo cellular interactions at the BBB. We used this model to evaluate the patho
