Outline of Research at the Start |
PTPN3分子がTreg細胞でどのような役割を持っているかは分かっていない。本研究では免疫チェックポイント分子PTPN3を抑制する免疫治療法開発を見据え、さらに研究を発展させ「PTPN3分子がTreg細胞諸機能に及ぼす影響を解析し、PTPN3抑制治療がTreg細胞機能も抑制できる新たな免疫治療となり得るか検証する」ことを主目的とする。

Outline of Final Research Achievements |
FOXP3+Treg cells and CD8+T cells numbers were compared with PTPN3 high expression area and PTPN3 low expression area in resected small cell lung cancer specimen. In PTPN3 high expression area cancer fibrosis is high, infiltrated FOXP3+Treg number is high and infiltrated CD8+T cell number is low. On the contrary, in PTPN3 low expression area cancer fibrosis is low, infiltrated FOXP3+Treg number is low and infiltrated CD8+T cell number is high. These results suggest that PTPN3 expression in cancer tissue contribute to the decrease of cancer tissue-infiltrated CD8/Treg cell number ratio and that it induces immune tolerance.

Academic Significance and Societal Importance of the Research Achievements |
PTPN3分子が小細胞肺癌において、FOXP3+Treg細胞の浸潤増加、CD8+T細胞の浸潤低下を制御していることが示唆され、PTPN3抑制が細胞性免疫能亢進を惹起するすることが示唆された。その機序として癌線維化の関与が示唆され、PTPN3抑制が癌微小環境の制御にも作用すること可能性が考えられた。
