Drugs delivered by exosomes may be efficiently absorbed by target tissues and cells with high specificity and lack of immunologic reactions. Thus, exosomes function as a popular tool to deliver multiple drugs to various target tissues. https://www.creative-biolabs.com/exosome/therapeutic-application-of-exosome.htm

Fuse with lysosome, which
degrade multivesicular
endosomes (MVE) contents.
