Outline of Final Research Achievements |
Based on the analysis of skin characteristics and barrier parameters of patients with atopic dermatitis, the skin barrier status of atopic dermatitis was broadly classified into three clusters and associated with the skin flora pattern. Each cluster was then associated with an animal model. One of the animal models, the MC903 application model, was used to investigate the possibility of skin care using indigenous bacteria identified from the skin flora of atopic dermatitis patients treated with bleach bath therapy (bath containing 0.005% sodium hypochlorite) and a significant anti-inflammatory effect was observed. These results provide proof of concept for a new method of skin care using indigenous skin bacteria in addition to conventional skin care with moisturizers and protective agents.

Academic Significance and Societal Importance of the Research Achievements |
スキンケアは、角層の水分保持を亢進させる保湿剤と、外来刺激物や抗原の表皮内への侵入を防ぐ保護剤の塗布、という発想でしか論じられることがなかった。本研究は、アトピー性皮膚炎患者の皮膚性状やバリア状態と皮膚細菌叢の密接な関連を明らかにし、細菌叢に介入することで皮膚の炎症や性状・バリア状態を改善させる新しいスキンケア手法の可能性を検証した研究である。 また、ヒトアトピー性皮膚炎に関するDeep phenotype情報を統合解析して、多彩な患者の皮膚状態を層別化し、それを動物モデル情報と突合してリバーストランスレーションに最適なモデルを得るという、将来の多研究に応用可能な研究手法の有用性を示している。
