血管内皮充当血液循环内容物与其流经的组织之间的半选择性屏障。在脓毒症和急性肺损伤 (ALI) 等破坏性炎症综合征中,该屏障的破坏会导致严重的器官功能障碍。 1-磷酸鞘氨醇 (S1P) 是一种内皮细胞通透性的内源性脂质调节剂,可通过肌动蛋白和连接蛋白重排以及由此产生的细胞骨架变化产生有效的屏障增强作用。这种 S1P 反应中的一个关键效应蛋白是粘着斑激酶 (FAK),这是一种高度保守的细胞质酪氨酸激酶,通过多个下游信号的催化参与整合素的接合和粘着斑 (FA) 的组装。受到 S1P 刺激后,内皮 FAK 发生特异性酪氨酸磷酸化,导致激酶激活并与其他效应分子动态相互作用,从而改善内皮屏障。 FAK 参与外周肌动蛋白细胞骨架重排以及细胞-基质 (FA) 和细胞-细胞(粘附连接)连接复合物强化,结合起来降低血管通透性。本综述总结了目前关于 FAK 通过 S1P 介导增强内皮屏障功能的作用的知识。
The vascular endothelium serves as a semi-selective barrier between the circulating contents of the blood and the tissues through which they flow. Disruption of this barrier results in significant organ dysfunction during devastating inflammatory syndromes such as sepsis and acute lung injury (ALI). Sphingosine 1-phosphate (S1P) is an endogenous lipid regulator of endothelial permeability that produces potent barrier enhancement via actin and junctional protein rearrangement and resultant cytoskeletal changes. A key effector protein in this S1P response is focal adhesion kinase (FAK), a highly conserved cytoplasmic tyrosine kinase involved in the engagement of integrins and assembly of focal adhesions (FA) through the catalysis of multiple downstream signals. After stimulation by S1P, endothelial FAK undergoes specific tyrosine phosphorylation that results in activation of the kinase and dynamic interactions with other effector molecules to improve the endothelial barrier. FAK participates in peripheral actin cytoskeletal rearrangement as well as cell-matrix (FA) and cell-cell (adherens junction) junctional complex strengthening that combine to decrease vascular permeability. This review summarizes the current knowledge of the role of FAK in mediating enhanced endothelial barrier function by S1P.
