Processes of astrocytes wrap tightly around capillaries in the brain. Tight junctions tightly seal endothelial cells of capillaries in the brain. Gap junctions tightly seal endothelial cells of capillaries in the brain. Spot desmosomes tightly link capillary endothelial cells together. The basement membrane of capillaries in the brain contains extremely small pores.
