Outline of Final Research Achievements

Regulatory T cells (Tregs) play an important role not only in immunological self-tolerance but also in various inflammatory diseases. In this study, we explored the possibility that Tregs redirected toward carcinoembryonic antigen (CEA) expressed on lung epithelia have potential to control allergic airway inflammation. Retrovirally transduced Tregs with chimeric antigen receptor (CAR) gene constituting scFv specific to CEA as an ectodomain and signaling domains derived from CD3zeta and CD28 as an endodomain exerted potent regulatory activity in vitro. Using a mouse model of allergic asthma, the effect of adoptively transferred CEA-specific CAR-Tregs on airway inflammation will be examined.

Academic Significance and Societal Importance of the Research Achievements

本研究では、気管支喘息患者の炎症局所、即ち気道上皮に恒常的に発現しているCEAでTregを活性化することで様々な疾患起因アレルゲンに対する過剰免疫応答によって発症する気管支喘息を制御することに特色があり、ステロイドによる炎症抑制作用とは作用機序が異なり、難治性喘息患者に対して有効な新規治療法となり得る。また、免疫抑制は炎症局所に限定し全身性の免疫抑制を伴わないことが期待され、感染症に対する抵抗力を削ぐことが無く、全身的な免疫抑制を伴う治療法に比較して優れた治療法になり得ると考えられる。
