Outline of Final Research Achievements

We have established an in vitro model of ARDS by co-culture of alveolar epithelial cells and LPS-activated neutrophils. In that model, energy metabolism of injured alveolar epithelial cells is significantly altered. Transcriptomic analysis by microarray revealed that insulin resistance pathway may be associated with the altered energy metabolism. Moreover, pharmacological inhibition of insulin signaling pathway protects alveolar epithelial cells from the injury. These results suggest that insulin resistance pathway may be a therapeutic target for lung injury.

Academic Significance and Societal Importance of the Research Achievements

本研究ではARDSを模した培養細胞実験系を用いることで,傷害を受けた肺胞上皮細胞において大きなエネルギー代謝パターンの変化が生じ,包括的な遺伝子発現の解析からインスリン抵抗性経路がその背景機序の一つである可能性が示唆された.インスリン抵抗性は高血糖をもたらすことから忌避すべきものと考えられているが,本研究の結果からはインスリン抵抗性の活性化が臓器保護効果を持つ可能性が示唆され,今後の研究の発展につながる成果をえることができた.
