Abstract
The present disclosure relates to therapeutic exosomes enriched in proteins that are present in the luminal surface of exosomes. The present disclosure provides methods of manufacturing exosomes enriched in proteins that are present in the luminal surface of exosomes, method of associating a therapeutic peptide or protein to the luminal surface of exosomes, and method of use, e.g., methods of therapeutic or diagnostic use. The methods of manufacture involve generating of luminal-surface-engineered exosomes that include one or more of the EV, e.g., exosome proteins at concentrations higher that those observed in wild type exosomes, a modification or a fragment of the EV, e.g., exosome protein, or a fusion protein of the EV, e.g., exosome protein, and a payload, e.g., biologically active molecule such as a therapeutic protein.
