Outline of Final Research Achievements

Pulmonary vascular endothelial cells (PVECs) function as an important pro-inflammatory source in ARDS, suggesting that modulation of inflammatory events at the endothelial level may have a therapeutic benefit. Dipeptidyl peptidase-4 (DPP4) inhibitors have been reported to have possible anti-inflammatory effects. However, the potential antiinflammatory effects of DPP4 inhibition on PVEC function and ARDS pathophysiology are unknown. Therefore, we evaluated the effects of sitagliptin, a DPP4 inhibitor in wide clinical use, on LPS-induced lung injury in mice and in human lung ECs in vitro. In summary, sitagliptin attenuates LPS-induced lung injury in mice and exerts anti-inflammatory effects on HLMVECs. These novel observations indicate DPP4 inhibitors may have potential as therapeutic drugs for ARDS.

Academic Significance and Societal Importance of the Research Achievements

難治性呼吸器疾患に対する新規治療戦略の開拓のターゲットとして、ARDSにおける肺血管内皮細胞の役割に注目している。ARDSに対する有効な治療方法は確立しておらず、何らかの新規治療戦略が必要である。ARDS初期の過剰な炎症反応を抑制しうる一つの分子が多くの細胞表面に発現しているCD26と考えている。このCD26の発現上昇は過剰な炎症に繋がりうる。そこでCD26活性を抑制しうるDPP4阻害薬であるシタグリプチンにARDS抗炎症作用があるかどうかを、マウスモデルおよびヒト肺細胞を使用して研究した。
