Outline of Final Research Achievements

In the present study, we evaluated detailed immunological aspects in clinical specimens from non-small cell lung cancer (NSCLC) patients. By using bispecific T-cell engager technology to assess the cytotoxicity of T cells, we found that the cytotoxicity of tumor-infiltrated T cells closely correlated with that of peripheral T cells. These results imply further applications to blood-based immune monitoring systems and predictive biomarkers for cancer immunotherapy.

Academic Significance and Societal Importance of the Research Achievements

本研究において末梢血T細胞活性測定法が腫瘍組織のT細胞機能の予測につながることが示唆されたことから、今後この測定法が免疫チェックポイント阻害薬の効果予測診断法として有用であることが示されれば、免疫チェックポイント阻害薬の効果がある患者さんを事前に予測して適切な治療を提供することにつながることが期待される。
