ZBP1/DAI 调节病毒诱导的程序性细胞死亡的激活机制尚不清楚。凯萨瓦达纳等人。表明 ZBP1 感知病毒核糖核蛋白,在甲型流感病毒感染时诱导细胞死亡。 RIG-I-IFNAR 信号的顶端激活上调 ZBP1 和流感诱导的 ZBP1 泛素化是 ZBP1 激活的关键事件。对流感病毒感染的先天感知会诱导程序性细胞死亡途径的激活。我们最近发现 Z-DNA 结合蛋白 1 (ZBP1) 是甲型流感病毒 (IAV) 的先天传感器。 ZBP1 介导的 IAV 传感对于触发受感染肺部的程序性细胞死亡至关重要。令人惊讶的是,人们对调节 ZBP1 激活以诱导程序性细胞死亡的机制知之甚少。在此,我们报道视黄酸诱导基因 I (RIG-I) 对 IAV RNA 的感知通过 RIG-I–MAVS–IFN-β 信号轴启动 ZBP1 介导的细胞死亡。 IAV 感染诱导 ZBP1 泛素化,表明 ZBP1 功能可能通过翻译后修饰进行调节。我们进一步证明ZBP1感知IAV的病毒核糖核蛋白(vRNP)复合物以触发细胞死亡。这些发现共同表明,ZBP1 激活需要 RIG-I 信号传导、泛素化和 vRNP 传感来触发 IAV 感染期间程序性细胞死亡途径的激活。本文描述的 ZBP1 激活机制可能对病毒诱导的细胞死亡具有更广泛的影响。
The activation mechanism of ZBP1/DAI to regulate virus-induced programmed cell death is not known. Kesavardhana et al. show that ZBP1 senses viral ribonucleoproteins to induce cell death upon influenza A virus infection. Apical activation of RIG-I–IFNAR signaling to upregulate ZBP1 and influenza-induced ZBP1 ubiquitination are critical events for ZBP1 activation. Innate sensing of influenza virus infection induces activation of programmed cell death pathways. We have recently identified Z-DNA–binding protein 1 (ZBP1) as an innate sensor of influenza A virus (IAV). ZBP1-mediated IAV sensing is critical for triggering programmed cell death in the infected lungs. Surprisingly, little is known about the mechanisms regulating ZBP1 activation to induce programmed cell death. Here, we report that the sensing of IAV RNA by retinoic acid inducible gene I (RIG-I) initiates ZBP1-mediated cell death via the RIG-I–MAVS–IFN-β signaling axis. IAV infection induces ubiquitination of ZBP1, suggesting potential regulation of ZBP1 function through posttranslational modifications. We further demonstrate that ZBP1 senses viral ribonucleoprotein (vRNP) complexes of IAV to trigger cell death. These findings collectively indicate that ZBP1 activation requires RIG-I signaling, ubiquitination, and vRNP sensing to trigger activation of programmed cell death pathways during IAV infection. The mechanism of ZBP1 activation described here may have broader implications in the context of virus-induced cell death.
