Outline of Research at the Start |
本申請研究は、食道扁平上皮癌における放射線照射と免疫チェックポイント阻害剤(ICI)の併用療法の開発を目指して、ICIの標的分子であるPD-L1の調節機序を、放射線照射とIFN-gamma誘導の観点、また、放射線照射とEpithelial Mesenchymal Transitionの観点から、細胞レベル、分子生物学的レベルで詳細に解析し、臨床検体を用いた質の高いTranslational Researchを展開することを骨子としている。

Outline of Final Research Achievements |
We have accumulated knowledge that irradiation induces immunogenic cell death and that irradiation is a promising partner for ICI as a combined immunotherapy. Therefore, the present study aims to clarify how irradiation affects the tumor immune environment and maximizes the synergistic effect with ICI. A prospective observational study, the 'E-circuit trial', was designed and conducted in 20 patients. We found that irradiation induced T cells that recognized neo-antigens, and that these T cells were re-invigorated by nivolumab.
