Outline of Research at the Start

遺伝子発現を介した細胞機能の調節は免疫応答においても非常に重要である。本研究では、T細胞を介した免疫応答における転写因子JunBの役割を明らかにする。T細胞で特異的にJunBを欠損するマウスを用いて、通常の飼育環境下におけるT細胞の分化状態や機能を解析するほか、複数の炎症性病態モデルを誘導した際のT細胞の活性化を検討する。また、網羅的な遺伝子解析手法を用いることにより、JunBの標的遺伝子と生理機能との関係を明らかにする。

Outline of Final Research Achievements

Regulatory T cells (Treg cells) are known to play important roles in preventing excess immune reactions, how Treg cells are generated in vivo has not been fully elucidated. We revealed that Treg cells are not efficiently developed in mice deficient in the transcription factor JunB due to impairment in activation of IL-2 signaling. We also found that dextran sulfate sodium (DSS)-induced colitis, a mouse model for human ulcerative colitis, was exacerbated in JunB-deficient mice because of the reduction in the Treg cell number. Injection of a high dose of IL-2 into JunB-deficient mice resulted in mitigation of the colitis by expansion of Treg cells.

Academic Significance and Societal Importance of the Research Achievements

潰瘍性大腸炎などの炎症性疾患や多くの自己免疫疾患は、治療戦略はもとより、発症・増悪メカニズムについても詳細が明らかでない。本研究により、転写因子JunBがIL-2シグナルの活性化を通じてTreg細胞の誘導に関与し、大腸炎モデルを抑制することが明らかになったので、JunBのはたらきやIL-2シグナルの強度を調節するというアプローチにより、Treg細胞を介して症状を緩和するという新しい治療法の可能性が示された。
