Outline of Final Research Achievements

ARDS is characterized by pulmonary edema and extensive hyperinflammation (diffuse alveolar damage: DAD), and once ARDS develops, it is refractory to treatment, making it important to prevent its development. We reported here that CCL23, which regulates bone marrow function, significantly suppress blood cell-induced cytokine production and accumulation of bone marrow-derived leukocytes in the lungs. And also, we developed an in vivo model to analyze the effect of PMX-DHP(polymyxin-B direct hemoperfusion) therapy in primates to analyze the perioperative PMX-DHP therapy, its biological effects, and its preventive effects on the release of leukocytes from the bone marrow into the circulation and their accumulation in the lungs after surgery.

Academic Significance and Societal Importance of the Research Achievements

手術侵襲、および術後炎症性サイトカインストームから惹起され、循環血へ放出される骨髄由来白血球は未熟な活性化白血球であり、これらの肺循環への集積は肺障害の病態形成において重要なkey factorである。術後急性肺障害の死亡率は40-50%と報告され、救急治療、重症管理を要する重篤な病態で、その発症は補体活性化、炎症性サイトカイン、凝固異常を介した白血球の活性化が主な要因とされ、さらにARDSに至れば難治性となるが故に、その発症予防が重要である。骨髄由来白血球、および高サイトカイン血症の制御による術後肺障害発症メカニズムの解明と予防手段の解析に繋がると考える。
