| Outline of Final Research Achievements |
The purposes of the research are (1) to show the usefulness of making exosome catalog by the analysis of exosome physicochemical property-pharmacokinetics relationship and (2) to establish drug incorporation method into exosomes without character changes for the development of exosome DDS. Through (1), we have established the evaluation method of exosome physicochemical property and pharmacokinetics (including cellular uptake). Especially, we succeeded in the potential of affinity difference against cancer cells between some types of exosomes. Moreover, we developed labeling method of positron emitter onto exosomes for pharmacokinetics analysis by PET imaging. In (2), we have developed the method of siRNA incorporation into exosomes by liposome-based membrane fusion without size changes. Using these techniques, we are going to evaluate the pharmacokinetics of the exosomes in mice, analyze the relationship and make a catalog for targeting cancer.
