Abstract

Cumulative evidence has shown that mechanical and frictional forces exert distinct effects in the multi-cellular aortic layers and play a significant role in the development of abdominal aortic aneurysms (AAA). These mechanical cues collectively trigger signaling cascades relying on mechanosensory cellular hubs that regulate vascular remodeling programs leading to the exaggerated degradation of the extracellular matrix (ECM), culminating in lethal aortic rupture. In this review, we provide an update and summarize the current understanding of the mechanotransduction networks in different cell types during AAA development. We focus on different mechanosensors and stressors that accumulate in the AAA sac and the mechanotransduction cascades that contribute to inflammation, oxidative stress, remodeling, and ECM degradation. We provide perspectives on manipulating this mechano-machinery as a new direction for future research in AAA.

摘要

越来越多的证据表明,机械力和摩擦力在主动脉的多层细胞中发挥着不同的作用,并在腹主动脉瘤(AAA)的发展中起重要作用。这些机械信号共同触发依赖于机械感受细胞枢纽的信号级联反应,这些枢纽调节血管重塑程序,导致细胞外基质(ECM)过度降解,最终导致致命的主动脉破裂。在这篇综述中,我们提供了最新信息,并总结了目前对AAA发展过程中不同细胞类型的机械转导网络的理解。我们关注在AAA瘤腔内积累的不同机械感受器和应激源,以及导致炎症、氧化应激、重塑和ECM降解的机械转导级联反应。我们提供了操纵这种机械机制的观点,作为AAA未来研究的一个新方向。
