Outline of Research at the Start

IL-26は多様な慢性炎症疾患で発現増加が報告されている新規炎症性サイトカインだが、マウスに欠損した遺伝子のため従来のマウス疾患モデルでは見逃されていたヒト炎症の重要な因子である。IL-26が多臓器線維化・過剰な血管新生を引き起こし、肺・肝臓など全身臓器の炎症や関節炎の増悪にも関与することを見出した。本研究では申請者ら独自のIL-26研究ツールを用いた疾患モデルにより、慢性炎症におけるIL-26の機能を解明し、新規抗炎症療法を開発するための基盤研究を行う。

Outline of Final Research Achievements

IL-26 is a Th17 cytokine, with its gene being absent in rodents. Without accessible animal models due partly to the absence of the IL-26 gene in mice, IL-26 role in inflammatory disorders is not clearly characterized. Utilizing human IL-26 bacterial artificial chromosome transgenic (hIL-26Tg) mice, we have investigated the in vivo effects of IL-26 in various inflammation models such as psoriasis model, colitis model, arthritis model and chronic graft-versus-host disease models. IL-26 is associated with the exacerbated inflammation and fibroproliferation. Moreover, IL-26 markedly enhanced the infiltration of T cells and neutrophils and augmented Th17 response associated with enhanced levels of G-CSF, IL-1β and IL-6.
Taken together, our data elucidate the novel in vivo effects of IL-26 and strongly suggest that a humanized neutralizing anti-IL-26 monoclonal antibody may be a potential therapeutic agent for the treatment of refractory chronic inflammatory diseases.

Academic Significance and Societal Importance of the Research Achievements

近年、サイトカインやその受容体に結合してその機能を阻害する抗体医薬が様々な自己免疫疾患やアレルギー疾患の治療薬として承認されている。IL-26は主にTh17細胞が産生する炎症性サイトカインだが、マウスには欠損した遺伝子であり、従来のマウス疾患モデルでは見逃されていた因子であるため、まだその機能については明らかにすべき点は多い。
代表者らはヒトIL-26トランスジェニックマウスを用いて、様々な炎症性疾患モデルにおけるIL-26の役割を解明し、IL-26の中和抗体を開発した。IL-26抗体が炎症と組織の線維化を制御できる新たな治療薬となることが期待される。
