Extracellular vesicles (EVs) have a significant impact on the pathophysiological processes associated with various diseases such as tumors, inflammation, and infection. They exhibit molecular, biochemical, and entry control characteristics similar to viral infections. Viruses, on the other hand, depend on host metabolic machineries to fulfill their biosynthetic requirements. Due to potential advantages such as biocompatibility, biodegradation, and efficient immune activation, EVs have emerged as potential therapeutic targets against the SARS-CoV-2 infection. Studies on COVID-19 patients have shown that they frequently have dysregulated lipid profiles, which are associated with an increased risk of severe repercussions. Lipid droplets (LDs) serve as organelles with significant roles in lipid metabolism and energy homeostasis as well as having a wide range of functions in infections. The down-modulation of lipids, such as sphingolipid ceramide and eicosanoids, or of the transcriptional factors involved in lipogenesis seem to inhibit the viral multiplication, suggesting their involvement in the virus replication and pathogenesis as well as highlighting their potential as targets for drug development. Hence, this review focuses on the role of modulation of lipid metabolism and EVs in the mechanism of immune system evasion during SARS-CoV-2 infection and explores the therapeutic potential of EVs as well as application for delivering therapeutic substances to mitigate viral infections.
细胞外囊泡(EVs)对与各种疾病相关的病理生理过程有重大影响,如肿瘤、炎症和感染。它们表现出与病毒感染相似的分子、生化和进入控制特性。另一方面,病毒依赖宿主代谢机制来满足其生物合成需求。由于具有生物相容性、可生物降解和有效免疫激活等潜在优势,EVs 已成为针对 SARS-CoV-2 感染的潜在治疗靶点。对 COVID-19 患者的研究表明,他们经常出现脂质谱失调,这与严重后果的风险增加有关。脂滴(LDs)作为细胞器,在脂质代谢和能量稳态中具有重要作用,并且在感染中具有广泛的功能。脂质(如鞘脂神经酰胺和类二十烷酸)或参与脂质生成的转录因子的下调似乎抑制了病毒的增殖,这表明它们参与了病毒的复制和发病机制,并强调了它们作为药物开发靶点的潜力。因此,本综述重点关注在 SARS-CoV-2 感染期间免疫系统逃避过程中脂质代谢和 EVs 的调节作用,并探讨 EVs 的治疗潜力以及应用它们来递送治疗物质以减轻病毒感染。
