核因子κB(NF-κB)家族是控制细胞增殖、凋亡、干扰素和促炎因子表达以及病毒感染的主要转录因子。在病毒感染期间,宿主先天免疫系统感知病毒产物,例如病毒核酸,以激活先天防御途径,包括NF-κB信号传导轴,从而抑制病毒感染。在这些NF-κB信号通路中,不同类型的泛素化已被证明参与信号级联的不同步骤。最新研究发现,病毒还通过调节NF-κB信号通路中的泛素化,激活病毒基因表达或抑制宿主NF-κB活化和炎症反应,从而促进病毒感染。了解病毒感染过程中NF-κB信号转导中泛素化的作用,将有助于我们进一步了解NF-κB信号转导的调控机制,并为潜在的抗病毒治疗铺平道路。本文就泛素化在NF-κB信号转导中的作用进行了系统的综述,阐述了病毒如何通过泛素化调控NF-κB信号转导,并对今后的研究方向进行了展望。
The nuclear factor κB (NF-κB) family are the master transcription factors that control cell proliferation, apoptosis, the expression of interferons and proinflammatory factors, and viral infection. During viral infection, host innate immune system senses viral products, such as viral nucleic acids, to activate innate defense pathways, including the NF-κB signaling axis, thereby inhibiting viral infection. In these NF-κB signaling pathways, diverse types of ubiquitination have been shown to participate in different steps of the signal cascades. Recent advances find that viruses also modulate the ubiquitination in NF-κB signaling pathways to activate viral gene expression or inhibit host NF-κB activation and inflammation, thereby facilitating viral infection. Understanding the role of ubiquitination in NF-κB signaling during viral infection will advance our knowledge of regulatory mechanisms of NF-κB signaling and pave the avenue for potential antiviral therapeutics. Thus, here we systematically review the ubiquitination in NF-κB signaling, delineate how viruses modulate the NF-κB signaling via ubiquitination and discuss the potential future directions.
