Anti-miR oligonucleotides are often used for the functional inhibition of miRNAs; however, there are no studies regarding the regulation of exosomal miRNA functions. In this study, we attempted to develop a novel drug delivery system using anti-exosome antibody?anti-miR oligonucleotide complexes (ExomiR-Tracker) to hijack exosomes to carry anti-miR oligonucleotides inside exosome-recipient cells. We found that ExomiR-Tracker bound to the exosomes, and then the complexes were introduced into the recipient cells. We also found that anti-miR oligonucleotides introduced into the recipient cells can exhibit inhibitory effects on exosomal miRNA functions in vitro and in vivo. We believe that our strategy would be a promising one for targeting exosomal miRNAs., Pharmaceutics, 12(6), art.no.545; 2020}, title = {Development of Antibody?Oligonucleotide Complexes for Targeting Exosomal MicroRNA}, volume = {12}, year = {2020} }
