Research Summary

Kazuhiro  Kakimi(M.D., Ph.D.)

The activities of my laboratory are directed at understanding the dynamics of the anti-tumor immune response in vivo at the molecular, cellular and organismal levels and to develop more effective immunotherapy against cancer. I perform both clinical immunology in humans and basic preclinical immunology using animal models. I especially focus on the spatiotemporal analysis of anti-tumor immunity in both humans and experimental animals. Tumor-specific immunity is evaluated using standardized immunological assays and molecular analysis with NGS technology. By integrating all the information in each individual patient, comprehensive immunomonitoring can be performed and the most appropriate cancertherapy can be provided to patients in the future.
