Abstract: Exosomes are nanoscale vesicles derived from the inner membrane of cells, containing life information such as nucleic acids, proteins and lipids. They play an important role in life activities as a mechanism of intercellular communication. Compared to liposome carriers, exosomes are more stable, biocompatible and less immunogenic, and can penetrate biological barriers such as the blood-brain barrier and the placental barrier. This article focused on the basis of exosome vector targeting, the method of carrier loading and the current application progress and prospects.
