Research Abstract

本年度、制御性T細胞(Regulatory T cell, 以下Tregと略)の発生、および機能発現におけるFoxp3発現とTreg特異的エピゲノムの役割について解析した。Tregは転写因子Foxp3を特異的に発現するが、Foxp3の発現のみではTregに特有な遺伝子群(例えば、Helios、Eos)の発現、また抑制機能の発揮には不十分である。この不十分性を補完する重要な因子はTreg特異的なエピゲノム変化である可能性を探索した。まずゲノム全般についてメチル化領域を検索し、Treg特異的脱メチル化部位を決定した。次に、Foxp3を発現しないがFoxp3レポーター分子を発現するマウスを作製し、Foxp3とTreg特異的脱メチル化の関係を解析したところ、Helios、 Eosなどの遺伝子は、Foxp3に依存せずエピゲノム変化に依存すること、また、Foxp3発現とTreg特異的エピゲノム変化は独立して起こる事象であることを見出した。さらに、Treg特異的エピゲノムは、Treg抑制機能発現、全遺伝子発現プロファイルの形成、Treg細胞系譜の維持に必須の要素であることがわかった。つぎに、遺伝子発現調節におけるTreg特異的エピゲノムとFoxp3発現、それぞれの役割を明らかにするため、遺伝子発現パターンとゲノム上のFoxp3結合領域またはTreg特異的DNA脱メチル化領域との相関を解析した。Treg特異的エピゲノムは、定常状態における遺伝子発現促進に高い相関を示し、逆にFoxp3はTreg活性化条件下での遺伝子発現抑制に関わっていた。これらの結果は、両者の協調作用によりTreg分化が進行していく可能性を示唆している。この知見は、ヒトのTregを標的とした免疫応答制御法の開発に重要である。
