Abstract
Many researchers worldwide are currently trying to develop targeted molecular therapies such as nucleic acid medicines or antibody-drug conjugates for various diseases. Writing in Extracellular Vesicles and Circulating Nucleic Acids, Kim et al. summarized existing technologies for encapsulating therapeutic molecules into exosomes and introduced some human cell lines which are able to produce safe, effective therapeutic exosomes. Their review article offers the "magic bullet" for fighting threats to humanity such as the current coronavirus pandemic.
