Blood-brain barrier is a semipermeable border between the blood and brain. To keep homeostasis, the blood-brain barrier only allows essential substances to enter brain tissue. Astrocytes and pericytes in the brain and endothelial cells in the blood vessels are three types of cells that make up the blood-brain barrier. They work together to regulate the movement of molecules across the barrier.
