Outline of Final Research Achievements |
This study aims to elucidate the mechanisms by which Leptospira establishes itself in adipose tissue and to identify novel biomarkers for leptospirosis. Using an ex vivo human subcutaneous adipose tissue infection model, we observed the secretion of multiple adipokines upon Leptospira infection, particularly those involved in inflammatory and immune responses. Additionally, in an in vivo infection model using mouse-derived preadipocyte cell line 3T3-L1, pathogenic Leptospira induced lipolysis, utilizing extracellular glycerol as a carbon source. These findings suggest new diagnostic and therapeutic approaches for leptospirosis, potentially advancing the management of this significant infectious disease.

Academic Significance and Societal Importance of the Research Achievements |
本研究は、病原細菌レプトスピラが皮下脂肪組織に定着し、そこで増殖するメカニズムを一部解明しました。またこの際に、レプトスピラが脂肪組織に脂肪分解を起こすことも見出しました。この発見は、レプトスピラ症の早期診断に役立つ新たなバイオマーカーの開発に繋がる可能性があります。レプトスピラ症は、軽度の風邪様症状から重篤なワイル病に進行することがあり、早期診断と治療が非常に重要です。この研究は、社会全体にとって感染症対策の向上に寄与し、農業や畜産業の経済的損失を減少させる効果も期待されます。
