Outline of Final Research Achievements |
With administration of PPARγ agonist to injured rat vocal folds, the infiltration of inflammatory macrophages was suppressed and macrophage polarity was regulated from inflammatory to restorative. Furthermore, at remodeling phase, it was confirmed that fibrosis was suppressed and tissue repair was promoted. These results suggest that inflammatory macrophages and PPARγ activity may be therapeutic targets for fibrotic diseases.

Academic Significance and Societal Importance of the Research Achievements |
本研究では、ラットの損傷声帯にPPARγアゴニストを投与することにより、損傷部位へのマクロファージの浸潤や極性がコントロールされ、最終的に声帯の線維化が軽減されることが示された。 本研究の結果は、上気道臓器の線維化予防はもとより、他臓器における線維化疾患にも応用が可能であり、革新的な治療法開発へとつながる可能性がある。
