We co-cultured primary rat brain microvascular endothelial cells (BMECs), pericytes, astrocytes and neurons in a Transwell BBB model in vitro. Then, we carried out quantitative analysis to compare transendothelial electrical resistance (TEER) values, as well as expression levels of tight junction proteins, ZO1 and JAM1, in the triple culture and the quadruple culture Transwell BBB models <italic>in vitro</italic>. According to the obtained data, the quadruple culture model of the BBB in vitro has advantages over the triple culture model, since the presence of pericytes is accompanied by higher TEER values and higher expression levels of tight junction proteins in endothelial cells. The results presented in the study are consistent with the world scientific literature and confirm the hypothesis that pericytes not only offer mechanical support for endothelial cells, but also play a key role in signaling networks between different cell types of the neurovascular unit (NVU) and thus regulate the barrier functions of the BBB. According to this, co-culture of BMECs, astrocytes, and neurons with pericytes is essential for BMECs optimum phenotype and offers a closer representation of the <italic>in vivo</italic> environment.</p></abstract><trans-abstract xml:lang="ru"><p id="idm45181326204688">Цель настоящей работы заключалась в демонстрации преимущества четырехклеточной модели гематоэнцефалического барьера (ГЭБ) <italic>in vitro</italic> в сравнении с традиционной трехклеточной моделью, а также влияния перицитов на фенотип эндотелиальных клеток. В работе описан способ сокультивирования первичных эндотелиальных клеток микрососудов головного мозга, перицитов, астроцитов и нейронов в Tr-answell-модели ГЭБ <italic>in vitro</italic>. Проведен количественный анализ между показателями трансэндотелиального электрического сопротивления (ТЭС), а также между содержанием маркеров плотных контактов эндотелиальных клеток в трех- и четырехклеточной Transwel-моделях ГЭБ. Согласно полученным данным, присутствие перицитов сопровождается более высокими показателями ТЭС и более высоким содержанием белков плотных контактов. Представленные результаты согласуются с мировой научной литературой и подтверждают гипотезу о том, что перициты выполняют не только опорную функцию для эндотелиальных клеток, но и являются важным метаболическим звеном, регулирующим барьерные функции ГЭБ. Таким образом, сокультивирование клеток нейроваскулярной единицы (НВЕ) головного мозга с перицитами необходимо для формирования у эндотелиальных клеток фенотипа, приближенного к условиям в микроокружении НВЕ <italic>in vivo</italic>.</p></trans-abstract><kwd-group xml:lang="en"><kwd><italic>:</italic> blood-brain barrier</kwd><kwd>Transwell</kwd><kwd>pericytes</kwd><kwd>neurovascular unit</kwd><kwd>tight junctions</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>гематоэнцефалический барьер</kwd><kwd>Transwell</kwd><kwd>перициты</kwd><kwd>нейроваскулярная единица</kwd><kwd>плотные контакты</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Хилажева Е.Д., Бойцова Е.Б., Пожиленкова Е.А., Солончук Ю.Р., Салмина А.Б. 2015.
