Outline of Final Research Achievements

Artificial restorative materials are used for treatment of teeth. In particular, metals are prominently used in these artificial restorative materials, and these have been useful for improving the QOL of patients. However, some patients have inflammatory immune reactions such as metal allergies. Therefore, we examined to identify T cells that cause metal allergy. In this study, we succeeded in identifying metal-specific T cell receptor genes by gene-cloning T cell receptors that respond to metals

Academic Significance and Societal Importance of the Research Achievements

これまで、金属アレルギーは、T細胞が関与するアレルギーと考えられてきたが、その実態は明らかになっていなかった。本研究では、金属アレルギーモデルマウスにおいて、金属に反応する特異的T細胞が存在することを明らかにし、その金属反応性T細胞受容体の遺伝子を得ることができた。すなわち、本研究の学術的意義は、金属アレルギーにはT細胞が関与すること、金属に反応するT細胞受容体の遺伝子が存在することを証明した点である。
