Outline of Research at the Start

高齢化に伴い呼吸器疾患は増加しており、特に肺線維症については根本的な治療法がない。肺線維症の緩和を目指し、入手が容易で伝統的に創傷治癒効果があるとされてきたニワトリ卵殻膜に注目した。卵殻膜は、組織弾力性に寄与するⅢ型コラーゲンなどの細胞外マトリクスを誘導することや、卵殻膜の長期摂取が呼吸機能を改善することを明らかにしてきた。卵殻膜が細胞外マトリクスの恒常性を改善する機能を利用した、呼吸機能改善を目指す。さらに二光子励起顕微鏡を利用したバイオイメージングにより、生体への卵殻膜摂取効果をダイナミックに分析し、運動療法や呼吸法と組み合わせることで高齢社会における新規の健康戦略を開発する。

Outline of Final Research Achievements

In a human study, respiratory function was significantly increased in the group that ingested eggshell membrane compared to the control group. Radiolabeled eggshell membrane was also orally administered to mice to clarify the pharmacokinetics of eggshell membrane. Image analysis and gene expression analysis of mouse lung tissue and lung fibroblasts revealed that eggshell membrane significantly increased the expression level and secretion of decorin, which is known to prevent fibrosis and maintain healthy collagen fiber formation. Oral administration of eggshell membrane to mice models of pulmonary fibrosis significantly increased the level of decorin in the alveoli and reduced TAZ nuclear migration, a marker of pulmonary fibrosis. These results suggest that eggshell membrane improves the extracellular environment of lung tissue, thereby reducing pulmonary fibrosis and improving respiratory function.

Academic Significance and Societal Importance of the Research Achievements

高齢化に伴い呼吸器疾患は増加しており、特に肺線維症については根本的な治療法がない。肺線維症の緩和を目指し、入手が容易で伝統的に創傷治癒効果があるとされてきたニワトリ卵殻膜に注目した。我々は天然素材・卵殻膜が、弾力性に富む細胞外マトリクス成分であるデコリンやIII型コラーゲンの発現を誘導するという作用機序を利用し、呼吸機能改善や肺線維症にも有効なアプローチを開発した。卵殻膜の経口摂取は、肺組織の細胞外環境を改善することにより肺の健康に寄与する栄養/機能性食品として期待できる。
