Outline of Annual Research Achievements |
大腸がん症例における宿主側微小環境の対応(特に制御性T細胞 (Treg)を介した腫瘍免疫応答)について、客観的かつ経時的に評価しうる新しいシステムを構築するために研究を開始した。すなわちTregは種々の免疫機能を抑制する機能をもち、悪性腫瘍においても抗腫瘍免疫応答を抑制する。多くのがん種において腫瘍内浸潤Tregの存在は予後不良因子として報告されているが、大腸がんにおいては予後良好因子であるという報告もあり、controversialであった (Clin Cancer Res. 2012, Gastroenterology 2009)。さらに、従来FOXP3+CD4+ T cellが Tregとみなされていたが、FOXP3+ T cellの中に免疫機能を抑制しない分画が存在し、大腸がんにおいて腫瘍浸潤Tregの分画により予後が異なる(Saito T, et al. Nat. Med. 2016)。本研究では、大腸がん局所における悪性度に関連する腫瘍浸潤リンパ球のEffector Tregの割合に関連するmiR群を同定しその生物学的意義を検証する。 平成31年4月現在、14症例サンプル集積を完了した(男性5名/女性9名、平均年齢79歳、右側結腸3例/左側結腸6例/直腸5例)。TIL分離し、Sample 1-11 multi-region、Sample 10-14 serum, PBMCも採取した。現在、FACSにてsortingし、miRNA array提出している。それぞれの分画で発現の異なるmiRNAについてEnrichment解析を含めた機能解析を実施している。 これまでの結果SWI/SNF complexのEZH2遺伝子に注目し鋭意解析を進めている。また今後onlineのmiRNA toolであるmiEAAを用いて、Enrichment解析を施行する。
