Outline of Final Research Achievements

Applicability of a particle immunoelectrophoresis to exosome diagnosis was studied using breast cancer-derived exosomes. First, to extend the particle size range, the signal/background of the analysis system was improved. The particles up to 30 nm, which is not easy with conventional instruments, can be analyzed. Next, to advance the analytical method, the sample purification and the simultaneous evaluation of particle size-zeta potential were examined.
The difference in the expression of surface marker HER2, which is one of the indicators of malignancy of breast cancer, can be evaluated. This methodology is expected to make a substantial contribution to the ever-growing field of exosomal biomarker research.

Academic Significance and Societal Importance of the Research Achievements

細胞から分泌されるナノ粒子であるエクソソームは、がんなどの診断マーカーとして注目を集めている。しかし、エクソソームを対象にした診断や分析を実現するには、個々のエクソソームを分析する方法が必要とされていた。本研究では、これまで容易ではなかった30 nmの粒子の評価、個々のエクソソームの粒子径と表面タンパク質の情報の同時取得が可能になった。本研究で開発した技術により、エクソソームを対象にした医学や生物学の研究開発が今後ますます進み、エクソソームを用いる診断や薬の開発につながるものと期待される。
