• because most drugs cannot cross the blood–brain barrier (BBB) [115][116]. Besides, the accumulation of drugs at damaged areas of the BBB can lead to an unprotected, disrupted BBB and to disturbances of the brain microenvironment. In contrast, the integrity of the BBB can decrease the accumulation of drugs

• cells have also been found to have the ability to penetrate the blood‒brain barrier (BBB) in some special cases [26][27]. As a highly specialized structure, the BBB maintains homeostasis of the central nervous system [48]. The targeted delivery of drugs to the brain is challenging because of the limited

• Central nervous system diseases are a heavy burden on society and health care systems. Hence, the delivery of drugs to the brain has gained more and more interest. The brain is protected by the blood–brain barrier (BBB), a selective barrier formed by the endothelial cells of the cerebral microvessels
