Outline of Research at the Start

子宮頸がんの発がん因子としてヒトパピローマウイルス(HPV)感染が挙げられるが、メカニズムは不明である。本課題ではその機構の一端を解明するために宿主の環境因子に着目し、子宮頸部腫瘍(CIN)の進展、退縮における腟マイクロバイオータの果たす役割を解明する。CIN患者において腟サイトカイン発現プロファイルを調べ、炎症にかかわるタンパク発現の多寡について解析する。さらに、腟マイクロバイオータが産生する低分子化合物を質量分析にて解析し、腟マイクロバイオームとの相関を調べる。これらの環境因子がウイルス複製に関与するか否かを解析する。これらの結果は将来のCINに関する診療・予防戦略の重要な情報となる。

Outline of Final Research Achievements

This study focused on changes in the vaginal environment as factors involved in the progression or regression of cervical neoplasms. As a result, it was found that changes in the vaginal microbiota are associated with alterations in vaginal inflammation. The protein NF-κB, which controls this inflammation response, was found to increase with the progression of lesions, suggesting a relationship between vaginal inflammation and lesion progression. Furthermore, small molecules that are upregulated along with this protein increase have been identified, suggesting the potential for using these molecules as indicators for early diagnosis and the development of cancer treatments in the future.

Academic Significance and Societal Importance of the Research Achievements

子宮頸がんの発がん因子としてヒトパピローマウイルス(HPV)感染は広く世の中に知られている。しかし、HPV感染者のなかで極一部しか子宮頸がんを発症しないことも判明しており、何が発がんを促進しているのかの原因は不明である。今回我々は腟内の細菌叢に着目し、細菌叢の乱れに伴う炎症が免疫反応を誘導するなどの変化をきたし、同時に代謝亢進がおきていることを明らかにした。この代謝反応を標的としたあらたな診断マーカーや治療標的など、新たな診療を展開するうえで重要な情報を提供した。
