Abstract: Neurological disorders including neurodegenerative diseases, brain tumors, and stroke are the second leading cause of death and the greatest cause of disability worldwide. However, it remains challenging to achieve effective drug delivery to the central nervous system for treatments of neurological diseases due to the blood-brain barrier (BBB). The function of the BBB is regulated by the physiological interactions between various types of cells in the neurovascular unit (NVU). In the NVU, the brain vasculature of the BBB is surrounded by brain pericytes, brain astrocytes, neurons, and microglia (Figure 1). Moreover, the NVU at the levels of arteries and veins includes contractile smooth muscle cells (Schaeffer and Iadecola, 2021).
