Sphingolipids are essential components of eukaryotic cells. In this review, we want to exemplarily illustrate what is known about the interactions of sphingolipids with various viruses at different steps of their replication cycles. This includes structural interactions during entry at the plasma membrane or endosomal membranes, early interactions leading to sphingolipid-mediated signal transduction, interactions with internal membranes and lipids during replication, and interactions during virus assembly and budding. Targeted interventions in sphingolipid metabolism - as far as they can be tolerated by cells and organisms - may open novel possibilities to support antiviral therapies. Human immunodeficiency virus type 1 (HIV-1) infections have intensively been studied, but for other viral infections, such as influenza A virus (IAV), measles virus (MV), hepatitis C virus (HCV), dengue virus, Ebola virus, and severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2), investigations are still in their beginnings. As many inhibitors of sphingolipid metabolism are already in clinical use against other diseases, repurposing studies for applications in some viral infections appear to be a promising approach.
鞘脂是真核细胞的重要组成部分。在本综述中,我们将举例说明关于鞘脂在病毒复制周期不同阶段与各种病毒相互作用的已知情况。这包括在质膜或内体膜进入过程中的结构相互作用、导致鞘脂介导信号转导的早期相互作用、复制过程中与内膜和脂质的相互作用,以及病毒组装和出芽过程中的相互作用。对鞘脂代谢进行有针对性的干预——只要细胞和生物体能够耐受——可能为支持抗病毒治疗开辟新的途径。人类免疫缺陷病毒1型(HIV-1)感染已得到深入研究,但对于其他病毒感染,如甲型流感病毒(IAV)、麻疹病毒(MV)、丙型肝炎病毒(HCV)、登革病毒、埃博拉病毒和严重急性呼吸综合征冠状病毒2型(SARS-CoV-2),研究仍处于起步阶段。由于许多鞘脂代谢抑制剂已在临床上用于治疗其他疾病,将其重新用于某些病毒感染的研究似乎是一种有前途的方法。
