Extracellular vesicles (EVs), which are cell released double layered membrane particles, have been found in every circulating body fluid, and provide a tool for conveying diverse information between cells, influencing both physiological and pathological conditions. Viruses can hijack the EVs secretory pathway to exit infected cells and use EVs endocytic routes to enter uninfected cells, suggesting that EVs and viruses can share common cell entry and biogenesis mechanisms. SARS-CoV-2 is responsible of the coronavirus disease 2019 (Covid-19), which may be accompanied by severe multi-organ manifestations. EVs may contribute to virus spreading via transfer of virus docking receptors such as CD9 and ACE2. Covid-19 is known to affect the renin angiotensin system (RAS), and could promote secretion of harmful EVs. In this scenario EVs might be linked to cardiovascular manifestations of the Covid-19 disease through unbalance in RAS. In contrast EVs derived from mesenchymal stem cells or cardiosphere derived cells, may promote cardiovascular function due to their beneficial effect on angiogenesis, fibrosis, contractility and immuno-modulation. In this article we assessed the potential impact of EVs in cardiovascular manifestations of Covid-19 and highlight potential strategies to control the extracellular signaling for future therapies.
细胞外囊泡(EVs)是细胞释放的双层膜颗粒,在每种循环体液中都有发现,它为细胞间传递各种信息提供了一种工具,影响生理和病理状况。病毒可以劫持EVs分泌途径以离开受感染细胞,并利用EVs内吞途径进入未感染细胞,这表明EVs和病毒可以共享共同的细胞进入和生物发生机制。严重急性呼吸综合征冠状病毒2(SARS-CoV-2)是2019冠状病毒病(Covid-19)的病原体,该病可能伴有严重的多器官表现。EVs可能通过转移病毒对接受体如CD9和血管紧张素转换酶2(ACE2)来促进病毒传播。已知Covid-19会影响肾素-血管紧张素系统(RAS),并可能促进有害EVs的分泌。在这种情况下,EVs可能通过RAS失衡与Covid-19疾病的心血管表现相关联。相比之下,源自间充质干细胞或心球衍生细胞的EVs,可能因其对血管生成、纤维化、收缩性和免疫调节的有益作用而促进心血管功能。在本文中,我们评估了EVs对Covid-19心血管表现的潜在影响,并强调了控制细胞外信号以用于未来治疗的潜在策略。
