自然杀伤(NK)细胞是天然的淋巴细胞,在病毒感染过程中表现出获得性免疫的特征。据报道,IRF8双等位基因突变可导致家族性NK细胞缺乏症和严重病毒感染的易感性;然而,该转录因子在调节NK细胞功能中的确切作用尚不清楚。在这里,我们证明了细胞固有的IRF8是NK细胞介导的对小鼠巨细胞病毒感染的保护所必需的。在病毒暴露期间,NK细胞通过白介素12(IL-12)信号和转录因子STAT4上调IRF8,从而促进IRF8基因位点的表观遗传重塑。此外,IRF8通过促进细胞周期基因的表达,并直接控制病毒驱动的NK细胞增殖的主要调节因子Zbtb32,促进了病毒特异性NK细胞的增殖。这些发现确定了IRF8在NK细胞介导的抗病毒免疫中的功能和细胞类型特异性调节,并提供了对IRF8突变患者病毒易感性的机制理解。人类IRF8突变和免疫缺陷之间的联系还知之甚少。亚当斯等人。证明通过促进病毒特异性NK细胞的增殖,IRF8是NK细胞介导的抗病毒免疫所必需的。
Natural killer (NK) cells are innate lymphocytes that display features of adaptive immunity during viral infection. Biallelic mutations in IRF8 have been reported to cause familial NK cell deficiency and susceptibility to severe viral infection in humans; however, the precise role of this transcription factor in regulating NK cell function remains unknown. Here, we show that cell-intrinsic IRF8 was required for NK cell-mediated protection against mouse cytomegalovirus infection. During virus exposure, NK cells upregulated IRF8 through interleukin-12 (IL-12) signaling and the transcription factor STAT4, which promoted epigenetic remodeling of the Irf8 locus. Moreover, IRF8 facilitated the proliferative burst of virus-specific NK cells by promoting expression of cell cycle genes, and directly controlling Zbtb32, a master regulator of virus-driven NK cell proliferation. These findings identify the function and cell type-specific regulation of IRF8 in NK cell-mediated antiviral immunity, and provide a mechanistic understanding of virus susceptibility in patients with IRF8 mutations. The link between human IRF8 mutations and immunodeficiency is poorly understood. Adams et al. demonstrate that IRF8 is required for NK cell-mediated antiviral immunity by promoting proliferation of virus-specific NK cells.
