Outline of Research at the Start

気管支喘息の長期罹患例では、気道リモデリングにより肺機能が低下する。気道リモデリングの病態にはTh2細胞が産生するIL-13や多くの細胞が産生するTGF-bの関与が示されているが未だ不明な点が多い。気道リモデリングの修復機転に関する知見はさらに少ない。近年、組織修復に重要な役割を果たす制御性T細胞(Treg)の亜集団Repair Tregの存在が示されたが、気道リモデリングにおけるRepair Tregの役割は不明である。本研究では気道リモデリングにおけるRepair Tregの働きを包括的に解析し、Repair Tregの移入により気道リモデリングの修復を図る新規喘息治療法の基盤を構築する。

Outline of Final Research Achievements

It is commonly believed that airway remodeling in asthma is irreversible, but the scientific evidence supporting this notion is scant. Recently, epithelial stem cells have been shown to memorize past inflammation and alter their reactivity in the skin; however, the involvement of epithelial cell inflammatory memory in airway remodeling in asthma is unknown. In the present study, we comprehensively analyzed the inflammatory memory of airway epithelial cells in murine asthma models. We found that epigenetic changes in airway epithelial cells remained for a while after the disappearance of inflammation. Furthermore, after the disappearance of inflammation, airway epithelial cells produced significantly less pro-inflammatory cytokines in response to non-specific stimuli. These findings suggest that persistent epithelial cell dysfunction in asthma might be involved in the pathogenesis of airway remodeling.

Academic Significance and Societal Importance of the Research Achievements

喘息は人口の約6%が罹患する最も有病率の高いアレルギー性呼吸器疾患である。吸入ステロイド薬に加え、IgE、IL-5、IL-4/IL-13、TSLPを標的とした抗体医薬が臨床応用され、2型炎症が優位な喘息の治療選択肢は増えたが、未だに治療困難な患者が多数存在する。特に長期罹患例においては、気道リモデリングの進行により肺機能が低下する。一般に気道リモデリングは非可逆的変化と考えられており、気道リモデリングが進行した患者の治療は困難なため、アンメットメディカルニーズが存在する。本研究の達成により気道リモデリングの修復が可能になれば、長期罹患喘息の新たな治療法の開発に至る可能性がある。
