Outline of Research at the Start

難治性重症喘息における気道過敏性と気道リモデリングに対する炎症性サイトカインTNFSF14(LIGHT)の役割を検討する。平滑筋特異的LIGHT受容体欠損マウスを用いて、ハウスダスト誘導性重症喘息モデルにおけるLIGHTの気道平滑筋制御の病的意義を検討する。ヒト気道平滑筋細胞を用いてLIGHTによる気道平滑筋制御のメカニズムを解明する。最終的にマウス喘息モデルへのLIGHT中和抗体投与による治療効果を検討し、重症喘息の気道過敏性と気道リモデリングを標的とした新規治療法の確立を目指す。

Outline of Final Research Achievements

TNFSF14 (LIGHT) is a TNF family cytokine which is highly produced in patients with severe asthma. Higher levels of soluble LIGHT in the sputum or BALF correlate with lower lung function and increased asthma severity. We aimed to clarify the role of LIGHT on airway smooth muscle (ASM) cells by using a mouse model of asthma and human primary ASM cells. LIGHT promoted ASM differentiation, proliferation, and increased contractility through the LTβR receptor on ASM via non-canonical NFκB signaling. In ASM-specific LTβR-deficient mice, AHR and remodeling in severe asthma were improved, suggesting that LIGHT-LTβR signaling could be a novel therapeutic target for severe asthma.

Academic Significance and Societal Importance of the Research Achievements

気道過敏性の残存や気道リモデリングは気管支喘息における難治病態であり、根本的治療は確立されていない。本研究ではLIGHTが気道平滑筋上のLTβRシグナルを介して気道平滑筋を直接制御することにより気道過敏性の亢進および気道リモデリングの促進に寄与していることを明らかにし、LIGHT-LTβRが重症喘息における難治病態に対する新規治療標的となる可能性を示唆した。
