| Outline of Final Research Achievements |
Application of hydrostatic pressure is a powerful method for modulating intermolecular interactions between protein and water molecules. We have developed a high-pressure microscope that is optimized both for the best image formation and for the stability to hydrostatic pressure up to 150 MPa. The developed apparatus allows us to visualize the structural and functional changes of molecular machines. By using high-pressure microscopy, we have developed a novel technique that controls the molecular machines working in living cells. The developed technique successfully demonstrated that application of pressures can increase the activity in living cells.

| Academic Significance and Societal Importance of the Research Achievements |
これまでの生命科学分野では、遺伝子操作や化学物質を添加することで、細胞内での生命活動を操作する研究が実施されてきた。本研究で開発した技術は、これらの既存の技術とは異なり、静水圧という「力」を用いた新しい細胞操作技術である。今後も研究を継続し、圧力による活性化を通じて、新しい医療技術の芽を育むことができるように努めていく。
