Outline of Final Research Achievements

We focused on the effect of recomodulin in ANCA associated vasculitis (AAV). Neutrophil extracellular traps (NETs) are deeply involved in the pathogenesis of AAV and lead to the vascular injury. We showed that in vitro experiment recomodulin inhibit NETs formation and protect endothelium during vascular injury. Furthermore, rTM ameliorated AAV manifestation in AAV model animal. The treatment of rTM would be novel therapeutic agent in AAV patients.

Academic Significance and Societal Importance of the Research Achievements

ANCA関連腎炎は壊死性半月体形成性糸球体腎炎や肺出血を呈する重篤な疾患であり、近年強力な免疫抑制治療により寛解導入率は向上してきたが、治療関連感染症死が60%と非常に多いため、依然として予後は不良であり、特異的な治療の開発が必要である。本治療は、過剰な免疫抑制を引き起こさずに病態を改善する可能性があり、またすでに敗血症/DIC病態に対して臨床使用され安全性も確認されており、新規治療薬として臨床応用できる可能性がある。
