Abstract
AbstractThe blood‐brain barrier (BBB) poses daunting challenges in treating diseases associated with the central nervous system (CNS). Recently, the traditional notion of the absence of the lymphatic system in the brain is evolving. The discovery of the glymphatic system in the brain has stimulated tremendous interest in developing new strategies for the treatment of CNS diseases. Leveraging the glymphatic system for CNS drug delivery may pave a new avenue to circumvent the BBB and achieve efficient drug delivery. The review focuses on the glymphatic system of the brain, discussing potential factors affecting its functions and exploring their connections with the meningeal lymphatic system. Finally, the review provides an overview of the drug delivery methods through the glymphatic system to circumvent BBB and regulate brain immunity. These innovative drug delivery methods may significantly improve drug utilization and create new avenues for the treatment of brain diseases.
