Abstract

Acute respiratory distress syndrome (ARDS) is a severe respiratory condition characterized by increased lung permeability, hyper-inflammatory state, and fluid leak into the alveolar spaces. ARDS is a heterogeneous disease, with multiple direct and indirect causes that result in a mortality of up to 40%. Due to the ongoing Covid-19 pandemic, its incidence has increased up to ten-fold. Extracellular vesicles (EVs) are small liposome-like particles that mediate intercellular communication and play a major role in ARDS pathophysiology. Indeed, they participate in endothelial barrier dysfunction and permeability, neutrophil, and macrophage activation, and also in the development of a hypercoagulable state. A more thorough understanding of the variegated and cell-specific functions of EVs may lead to the development of safe and effective therapeutics. In this review, we have collected evidence of EVs role in ARDS, revise the main mechanisms of production and internalization and summarize the current therapeutical approaches that have shown the ability to modulate EV signaling.

摘要

急性呼吸窘迫综合征(ARDS)是一种严重的呼吸系统疾病,其特征为肺通透性增加、过度炎症状态以及液体漏入肺泡腔。ARDS 是一种异质性疾病,有多种直接和间接的病因,死亡率高达 40%。由于持续的新冠疫情,其发病率增加了十倍。细胞外囊泡(EVs)是小的脂质体样颗粒,介导细胞间通讯,并在 ARDS 病理生理学中发挥主要作用。事实上,它们参与内皮屏障功能障碍和通透性、中性粒细胞和巨噬细胞的激活,以及高凝状态的发展。更深入地了解 EVs 的多样化和细胞特异性功能可能会导致安全有效的治疗方法的发展。在这篇综述中,我们收集了 EVs 在 ARDS 中的作用的证据,回顾了主要的产生和内化机制,并总结了目前已显示出调节 EV 信号能力的治疗方法。
