Numerous viruses hijack cellular protein trafficking pathways to mediate cell entry or to rearrange membrane structures thereby promoting viral replication and antagonizing the immune response. Adaptor protein complexes (AP), which mediate protein sorting in endocytic and secretory transport pathways, are one of the conserved viral targets with many viruses possessing AP-interacting motifs. We present here different mechanisms of viral interference with AP complexes and the functional consequences that allow for efficient viral propagation and evasion of host immune defense. The ubiquity of this phenomenon is evidenced by the fact that there are representatives for AP interference in all major viral families, covered in this review. The best described examples are interactions of human immunodeficiency virus and human herpesviruses with AP complexes. Several other viruses, like Ebola, Nipah, and SARS-CoV-2, are pointed out as high priority disease-causative agents supporting the need for deeper understanding of virus-AP interplay which can be exploited in the design of novel antiviral therapies.
许多病毒劫持细胞蛋白运输途径来介导细胞进入或重新排列膜结构,从而促进病毒复制并拮抗免疫反应。衔接蛋白复合物(AP)介导内吞和分泌运输途径中的蛋白分拣,是保守的病毒靶标之一,许多病毒具有与 AP 相互作用的基序。我们在此介绍了病毒干扰 AP 复合物的不同机制,以及允许有效病毒增殖和逃避宿主免疫防御的功能后果。这种现象的普遍性可以从以下事实中得到证明,即在所有主要的病毒家族中都有 AP 干扰的代表,本综述涵盖了这些家族。描述最详细的例子是人类免疫缺陷病毒和人类疱疹病毒与 AP 复合物的相互作用。还有一些其他病毒,如埃博拉病毒、尼帕病毒和 SARS-CoV-2,被指出是高优先级的致病因子,这支持了深入了解病毒-AP 相互作用的必要性,这可以在设计新型抗病毒疗法中得到利用。
