Obana MasanoriAssociate professor

I have experience conducting drug discovery research at a pharmaceutical company and am currently involved in biomedical research. The goal of my research is to develop novel therapeutic strategies for patients suffering from diseases. I will contribute to broadening the scope of life sciences by promoting interdisciplinary research and valuing free-thinking.

Research theme

Development of novel therapeutic strategies for chronic kidney disease based on the elucidation of the pathological mechanisms

Chronic kidney disease (CKD) is attracting attention as a new national disease. Because CKD is a risk factor not only for the development of end-stage kidney disease but also for the cardiovascular diseases, novel therapeutic strategies to prevent and/or mitigate CKD are urgently needed. To develop novel strategies for CKD, we are searching for new molecules involved in the pathogenesis of CKD.

Research on the pathogenesis of cardiovascular diseases and myocardial regeneration

Japan is expected to face a heart failure pandemic due to the super-aging society. We are conducting research on the role of inflammatory cells in cardiac diseases and the self-repair ability of cardiomyocytes to development novel therapies for heart failure.
