Keywords敗血症 / microRNA / 血小板 / 遺伝子治療
Outline of Research at the Start

患者予後と関連する敗血症時の血小板数減少の原因として、過度の血小板活性化と、引き続き起こる血小板細胞死の現象が関与すると考えている。その機序と新しい予防法・治療法を見出すために、次世代シーケンサーを用いた血小板内と、血漿中の網羅的なmicroRNA(miRNA)発現解析等を通じて、その病態解析を展開したい。

Outline of Final Research Achievements

The activation of intraplatelet pyroptosis-related inflammasome and cell adhesion molecules increases platelet consumption despite the increase in the production of platelets in patients with sepsis who have decreased platelet counts. Furthermore, altered miRNAs may serve as indicators for predicting a decrease in platelet counts.

Academic Significance and Societal Importance of the Research Achievements

敗血症における血小板の動態とその調節機構に関する理解を深めることに学術的な意義があります。敗血症治療における新たな介入点を提供するかもしれません。また、miRNAの変化が血小板数の減少を予測するバイオマーカーとして機能する可能性を示すことは、敗血症の早期診断や治療の改善に寄与する可能性があります。
敗血症は世界中で重大な健康問題となっており、早期診断と効果的な治療が患者の生存率を大きく向上させることができます。これにより、敗血症による死亡率の低減や治療費の削減に貢献すると考えられます。
