血管内皮是一层薄薄的内皮细胞(EC),排列在血管的内表面,是血液和所有组织之间的关键界面。当内皮暴露于各种损伤如促炎细胞因子、氧化应激、高血压、高血糖、衰老和剪切应力时,发生EC活化、功能障碍和血管炎症。这些损伤导致一系列疾病状态的发病机制,包括动脉粥样硬化。一些信号通路,尤其是核因子κB介导的信号通路,在这些病理生理过程中起着至关重要的作用。最近,microRNAs(miRNAs)已成为EC功能的重要调控因子,通过微调基因表达。在这篇综述中,我们讨论了如何调节EC功能和血管炎症反应的各种病理生理刺激。了解miRNA在EC激活和功能障碍中的作用可能为控制动脉粥样硬化和其他慢性炎症性疾病状态提供新的靶点和治疗机会。
The vascular endothelium, a thin layer of endothelial cells (ECs) that line the inner surface of blood vessels, is a critical interface between blood and all tissues. EC activation, dysfunction, and vascular inflammation occur when the endothelium is exposed to various insults such as proinflammatory cytokines, oxidative stress, hypertension, hyperglycemia, aging, and shear stress. These insults lead to the pathogenesis of a range of disease states, including atherosclerosis. Several signaling pathways, especially nuclear factor κB mediated signaling, play crucial roles in these pathophysiological processes. Recently, microRNAs (miRNAs) have emerged as important regulators of EC function by fine-tuning gene expression. In this review, we discuss how miRNAs regulate EC function and vascular inflammation in response to a variety of pathophysiologic stimuli. An understanding of the role of miRNAs in EC activation and dysfunction may provide novel targets and therapeutic opportunities for controlling atherosclerosis and other chronic inflammatory disease states.
