Outline of Final Research Achievements

In this study, we examined the mechanism of how HMGB1 promotes neutrophil migration and the importance of HMGB1 in the pathogenesis of inflammatory diseases. Interestingly, administration of HMGB1-targeting inhibitor ISM ODN into ConA-treated mice suppressed liver inflammation and neutrophil infiltration. ISM ODN treatment also reduced B16F10 tumor growth, suggesting that the promotion of neutrophil infiltration by HMGB1 augments the liver inflammation and tumor growth. To further study HMGB1-induced neutrophil migration in vivo, we generated knock-in mice that constantly release HMGB1 extracellularly.

Academic Significance and Societal Importance of the Research Achievements

HMGB1は炎症疾患病態を増悪するDAMPsの代表的な分子の一つとして捉えられている。HMGB1に対する阻害剤や中和抗体が多数作成され、実際に種々の病態を抑制することも報告されているが、HMGB1が実際にどのように炎症を促進しているのか、そのメカニズムには未だ不明な点が多い。本研究の結果から、HMGB1は好中球の遊走を介して炎症を促進する可能性が示唆された。実際、HMGB1を阻害すると、マウス肝炎モデルおよび腫瘍モデルにおいて好中球の炎症部位への浸潤が阻害された。HMGB1を標的とした治療法の開発において、好中球の割合が指標になる可能性が示唆された。
