Fig. 4From: Immune cells: potential carriers or agents for drug delivery to the central nervous systemThe utilization of immune cells as a delivery system for central nervous system drugs has been explored through various approaches. These include the direct use of immune cells as transport vehicles (a), the development of immune cell membrane-camouflaged nanoparticles (b), and the creation of exosome-loaded nanoparticles/drugs (c).
