摘要
背景:近年来,PCSK9 的生理作用的许多方面已被阐明,特别是关于其在脂质代谢、心血管风险中的作用以及其在先天免疫中的作用。越来越多的证据表明 PCSK9 参与病毒感染(主要是 HCV)的发病机制,以及调节宿主对细菌感染(主要是败血症和感染性休克)的反应。此外,PCSK9 的作用已被研究为疟疾感染发病机制和疾病严重程度的关键步骤。目的:本文的目的是回顾现有已发表的关于 PCSK9 在多种传染病中的作用的文献。结论:除了正在进行的关于在 HIV 感染患者中抑制 PCSK9 以治疗 HIV 和 ART 相关的高脂血症的研究外,临床前研究表明 PCSK9 如何参与减少 HCV 的复制。此外,还提出了 PCSK9 抑制对登革热和 SARS-CoV-2 病毒感染的保护作用。有趣的是,已在脓毒症患者中描述了高血浆 PCSK9 水平。最后,据报道 PCSK9 编码基因的功能丧失可能会降低疟疾感染的死亡率。
关键词: HCV、HIV、败血症、原虫感染、病毒感染、细菌感染、免疫。
