骨髓细胞表达内在抗病毒因子是最近公认的限制慢病毒复制的机制。进入这些细胞的病毒必须制定策略来逃避细胞抗病毒因子,以建立有效的感染。通过研究感染骨髓细胞所必需的病毒编码蛋白的细胞靶标,现在已经更好地了解了细胞内在的抗病毒策略。最近的研究结果深入了解了慢病毒辅助蛋白 Vpx、Vpr 和 Vif 如何抵消骨髓细胞中的抗病毒因子,包括 SAMHD1、APOBEC3G、APOBEC3A、UNG2 和尿嘧啶。在这里,我们回顾了目前对细胞抗病毒因子如何发挥作用的分子基础以及拮抗它们以促进病毒传播和传播的病毒对策的理解。
The expression of intrinsic antiviral factors by myeloid cells is a recently recognized mechanism of restricting lentiviral replication. Viruses that enter these cells must develop strategies to evade cellular antiviral factors to establish a productive infection. By studying the cellular targets of virally encoded proteins that are necessary to infect myeloid cells, a better understanding of cellular intrinsic antiviral strategies has now been achieved. Recent findings have provided insight into how the lentiviral accessory proteins, Vpx, Vpr and Vif counteract antiviral factors found in myeloid cells including SAMHD1, APOBEC3G, APOBEC3A, UNG2 and uracil. Here we review our current understanding of the molecular basis of how cellular antiviral factors function and the viral countermeasures that antagonize them to promote viral transmission and spread.
