| Research Abstract |
It is necessary to develop drug delivery system (DDS) to give a treatment using miRNA which targets HCV. In this study we examined to apply exosome to DDS for miRNA. We purified the exosomes from the cells which produced GE11 with the partial aliment of the ligand for EGFR and gave the target cell specificity. We produced the exosomes contain miRNA to gene transfer into the exosome-producing cells and confirmed that it was included in purified exosomes. We confirmed that the exosomes specifically performed delivery to the xenografted human cancer cells in mice. So we showed possibility to apply to treatment of the HCV by the exosomes containing miRNA which targets HCV in this system.
