Bacterial pathogen-associated molecular pattern molecules (PAMPs) such as LPS activate the endothelium and can lead to lung injury, but the signaling pathways mediating endothelial injury remain incompletely understood. In a recent issue of the JCI, Gandhirajan et al. identify STIM1, an ER calcium sensor, as a key link between LPS-induced ROS, calcium oscillations, and endothelial cell (EC) dysfunction. In addition, they report that BTP2, an inhibitor of calcium channels, attenuates lung injury. This study identifies a novel endothelial signaling pathway that could be a future target for the treatment of lung injury.
细菌病原体相关分子模式分子(PAMPs),如 LPS,可激活内皮细胞,导致肺损伤,但介导内皮细胞损伤的信号通路仍不完全清楚。在最近的 JCI 中,Gandhirajan 等人确定了 STIM1,一种内质网钙传感器,作为 LPS 诱导的 ROS、钙振荡和内皮细胞(EC)功能障碍之间的关键联系。此外,他们还报告了钙通道抑制剂 BTP2 可减轻肺损伤。这项研究确定了一种新的内皮信号通路,它可能成为治疗肺损伤的未来靶点。
