抗病毒先天免疫反应包括诱导型干扰素(IFN)及其随后的自分泌和旁分泌作用,但其潜在的调节机制尚不完全清楚。我们在这里报道,CyLD是一种脱泛素酶,专门消化赖氨酸63连接的泛素链,是抗病毒宿主防御所必需的。CyLD的缺失使小鼠更容易受到水泡性口炎病毒(VSV)的感染。一直以来,缺乏CyLD的树突状细胞对VSV感染更敏感。这种功能缺陷不是由于缺乏I型干扰素的产生,而是由于干扰素受体信号的减弱。在没有CyLD的情况下,干扰素-β在诱导抗病毒基因和保护细胞免受病毒感染方面无效。这些发现证实了细胞色素D是一种新的抗病毒天然免疫调节剂,并提示了细胞色素D在调节干扰素受体信号中的作用。
An antiviral innate immune response involves induction of type I interferons (IFNs) and their subsequent autocrine and paracrine actions, but the underlying regulatory mechanisms are incompletely understood. Here we report that CYLD, a deubiquitinase that specifically digests lysine 63-linked ubiquitin chains, is required for antiviral host defense. Loss of CYLD renders mice considerably more susceptible to infection by vesicular stomatitis virus (VSV). Consistently, CYLD-deficient dendritic cells are more sensitive to VSV infection. This functional defect was not due to lack of type I IFN production but rather because of attenuated IFN receptor signaling. In the absence of CYLD, IFN-β is ineffective in the induction of antiviral genes and protection of cells from viral infection. These findings establish CYLD as a novel regulator of antiviral innate immunity and suggest a role for CYLD in regulating IFN receptor signaling.
