Outline of Final Research Achievements

The goal of this project is to generate a novel cancer therapy using the next generation chimeric antigen receptor (CAR)-expressing T cell that exerts anti-cancer effect more effectively than the conventional one. So far, the following results have been obtained;
1) The next generation CAR-T cell that concomitantly expresses CAR specific to a tumor antigen, a cytokine committing to T cell survival, and a chemokine inducing migration of T cells was generated. 2) The next generation CAR-T cells exerted more potent anti-tumor effects than the conventional one in several murine tumor models. 3) Molecular mechanisms underlying the potent tumoricidal efficacy of the next generation CAR-T cells were elucidated.
