| Outline of Final Research Achievements |
In activated T lymphocytes, velocity of random migration increases than resting lymphocytes and it may contribute to cytotoxicity against cancer. Addition of phosphorylated FTY720 (FTYP) suppresses the velocity of random migration in activated T lymphocytes and it leads to the decrease in cytotoxicity against cancer. In addition, we confirmed tha antitumor effect by the administration of FTYP using in vivo mice model. These results suggest that random migration in activated T lymphocytes may become a useful biomarker for therapeutic effect of cancer immunotherapy.
