Abstract

Permeability of the blood-brain barrier (BBB) represents a significant problem for most promising drugs used for treating brain diseases due to its high selectivity. The neurovascular unit, which includes neurons, interneurons, astrocytes, the basal membrane, smooth muscle cells, pericytes, endothelial cells, and the extracellular matrix, forms an anatomically and functionally cohesive structure that ensures effective regulation of cerebral blood flow. In vitro modeling of the BBB is a relevant and practically significant task for studying the penetration of therapeutic agents into the brain. This study presents a BBB model consisting of endothelial cells, pericytes, and astrocytes, which partially mimics the in vivo layers of the BBB. Despite some limitations, such as incomplete matching of astrocyte location, the model demonstrates high expression of tight junction proteins and optimal TEER values of the endothelial cell monolayer, making it suitable for studying the permeability of the BBB to various substances, including drugs and nanoparticles.
