Outline of Final Research Achievements

In recent years, several agents targeting immune checkpoint molecules have been developed. However, the effect of such immune checkpoints and their inhibitors on tumor microenvironment remains unclear. Recently, we have developed a novel single-cell technology, which enables us to investigate transcriptome, many surface markers, and T-cell and B-cell receptor repertoires at the same single cell. Here, using this novel single-cell technology, we have investigated the role of immune checkpoint molecules and the effect of their inhibitors in mouse tumor models.

Academic Significance and Societal Importance of the Research Achievements

本研究は、申請者が開発した革新的な単一細胞解析技術をがん免疫分野に初めて応用する試みである。今後、臨床検体におけるがん免疫微小環境や、それらの相互作用の解析など様々な研究への応用が可能であり、がん免疫研究の進展に大いに貢献できることが期待される。さらに、本研究性からに基づいて、がん免疫を標的とする薬剤の最適な組み合わせが検討されたり、バイオマーカー開発が進んだりすることが期待され、今後のがん免疫を標的とした治療戦略の改善に資すると予想される。
