肺缺血再灌注损伤(LIRI)是一个复杂的病理生理过程,具有高发病率和死亡率。 LIRI 的一个重要病理生理学特征是内皮屏障功能障碍,尽管该过程中涉及的机制仍不清楚。 VX765 是一种特异性 caspase-1 抑制剂,已被证明对多种疾病具有保护作用,包括败血症、动脉粥样硬化和神经胶质炎症性疾病。本研究的目的是确定 VX765 是否对 LIRI 具有保护作用。结果表明,肺缺血/再灌注(I/R)和缺氧/葡萄糖剥夺和复氧(OGD/R)诱导内皮细胞焦亡和以炎症反应为特征的屏障功能障碍。 VX765 治疗通过抑制体内和体外 caspase-1 成功缓解 I/R 和 OGD/R 诱导的内皮细胞焦亡和屏障功能障碍。总之,这些研究结果表明,VX765 可有效预防肺 I/R 诱导的内皮细胞焦亡和屏障功能障碍。
Lung ischemia reperfusion injury (LIRI) is a complex pathophysiological process with high morbidity and mortality. An important pathophysiological characteristic of LIRI is endothelial barrier dysfunction, although the mechanism involved in this process remains unclear. VX765, a specific caspase-1 inhibitor, has been shown to have a protective effect against several diseases including sepsis, atherosclerosis, and glial inflammatory disease. The objective of this study was to determine whether VX765 had a protective effect in LIRI. The results showed that lung ischemia/reperfusion (I/R) and oxygen/glucose deprivation and reoxygenation (OGD/R) induced endothelial pyroptosis and barrier dysfunction characterized by an inflammatory response. Treatment with VX765 successfully alleviated I/R- and OGD/R-induced endothelial pyroptosis and barrier dysfunction by inhibiting caspase-1 in vivo and in vitro. In conclusion, these findings showed that VX765 provided effective protection against lung I/R-induced endothelial pyroptosis and barrier dysfunction.
