Outline of Final Research Achievements |
This research is to identify molecules that serve as markers that allow cancer immunotherapeutic drugs to act selectively only on tumor cells to be treated, and to identify the abnormal molecular shapes. In this study, we first identified multiple candidate markers in the blood of patients who responded to nivolumab, a cancer immunotherapeutic drug. Then, we developed a method to identify the partial structure that forms the abnormal shape in this molecule and causes the functional abnormality, and completed the foundation for identifying the relevant structural part from patient specimens and connecting it to the development of treatment.

Academic Significance and Societal Importance of the Research Achievements |
本研究は「どうすれば、がん細胞のみを免疫治療できるか?」という点を腫瘍細胞に含まれる異常分子の特定構造を切り口に解決するものである。本研究はヒト免疫で認識され形成された抗原-抗体複合体から異常分子とその異常構造を特定する独自解析法を治療開発につなげる基盤研究である。本研究はがん免疫治療におけるがん細胞への治療効率性と正確性の向上につながり、がん治療成績の改善に発展する可能性がある。
