Outline of Final Research Achievements

MicroRNA, adjusting genome expression, is expected as biomarker of diagnosis or activity in autoimmune diseases. In this study, we evaluated usefulness of microRNA in ANCA associated vasculitis. We found on miR-5571 and miR-200c based on comprehensive search. We found that miR-5571 associated with MPO-ANCA positivity and miR-200c related with disease activity statistically.

Academic Significance and Societal Importance of the Research Achievements

miR-5571は疾患特異的な診断マーカー、miR-200cは疾患活動性のマーカーとなることが示唆された。これらのマイクロRNAのさらなる検討によってANCA関連血管炎の病態解明や臨床的なバイオマーカーとしての利用により、有効かつ安全な治療法の開発が期待される。
