| Outline of Final Research Achievements |
We investigated the effect of low dose X ray irradiation on the immune system by using mouse models. There were no significant difference in population of the lymphocytes; CD4+ T cells, CD8+ T cells, NK/NKT cells, and regulatory T cells by a single total body irradiation between 50 mGy and 200 mGy compared to the control group. On the other hand, an increase in antigen-specific CD8+ T cells was observed in continuous radiation exposed model mice (25 mGy x 10 days) immunized by ovalbumin. In conclusion, it was suggested that long term, low dose systemic radiation exposure might enhance specific cellular immunity.
