Outline of Research at the Start

研究代表者は、「樹状細胞と制御性T細胞のクロストーク」による免疫制御の重要性を世界に先駆けて見出し、その研究をリードしてきた。本研究では、これまでの研究成果を発展させ、樹状細胞と制御性T細胞のクロストークによる免疫制御の分子機構を解明する。将来、本研究成果を応用し、重篤な感染症や発がんリスクのない免疫抑制法の開発に貢献し、自己免疫疾患、アレルギー、移植片拒絶を特異的に治療することを目指す。

Outline of Final Research Achievements

To investigate the crosstalk between dendritic cells and regulatory T cells, analyzing some mouse models and human sample were perfomed. By analyzing gene expressions using samples and public databases, we found that regulatory T cells not only express Treg-specific genes such as Foxp3 and CTLA-4, but also other unique genes under these conditions. We also fond that a specific featured dendritic-cell subset may be correlated to regulatory T cells. We are continuing the analysis and working on important molecules related to dendritic cell-regulatory T cell crosstalk.

Academic Significance and Societal Importance of the Research Achievements

免疫学の基礎研究は多くの病気に関係するため、色々な病気の新しい治療法や医学の進歩に貢献できる。自らがこれまで発展させてきた樹状細胞と制御性T細胞のクロストークによる免疫制御というアプローチで、研究を進めることで、学術的な進歩や発展に加え、その成果を応用した治療法に結びつく可能性があり、社会的にも意義が高い。将来、少しでも病気に苦しむ患者様の役に立つことを目指し、研究を推進している。
