γ-Herpesviral immune evasion mechanisms are optimized to support the acute, lytic and the longterm, latent phase of infection. During acute infection, specific immune modulatory proteins limit, but also exploit, the antiviral activities of cell intrinsic innate immune responses as well as those of innate and adaptive immune cells. During latent infection, a restricted gene expression program limits immune targeting and cis-acting mechanisms to reduce the antigen presentation as well as antigenicity of latency-associated proteins. Here, we will review recent progress in our understanding of γ-herpesviral immune evasion strategies.
γ-疱疹病毒的免疫逃逸机制经过优化,以支持感染的急性、裂解期和长期、潜伏期。在急性感染期间,特定的免疫调节蛋白限制了细胞固有先天免疫反应以及先天和适应性免疫细胞的抗病毒活性,但也利用了这些活性。在潜伏感染期间,受限的基因表达程序限制了免疫靶向和顺式作用机制,以减少潜伏相关蛋白的抗原呈递和抗原性。在这里,我们将回顾我们对 γ-疱疹病毒免疫逃逸策略的理解的最新进展。
