在慢性病毒感染期间,CD4 T细胞的炎症功能逐渐减弱。同时,Th1细胞逐渐获得分泌细胞因子IL - 10的能力,IL - 10是抗病毒T细胞反应的一种强效抑制剂。为了确定这一适应过程背后的转录变化,我们应用了单细胞RNA测序方法,并评估了慢性感染期间表达IL - 10的CD4 T细胞的异质性。在此我们展示了一个具有明显Tfh特征的产生IL - 10的细胞群。利用IL - 10和IL - 21双报告基因小鼠,我们进一步证明IL - 10⁺IL - 21⁺共产生的Tfh细胞主要在慢性而非急性淋巴细胞性脉络丛脑膜炎病毒(LCMV)感染期间出现。重要的是,清除IL - 10⁺IL - 21⁺共产生的CD4 T细胞或特异性地在Tfh细胞中删除Il10会导致体液免疫和病毒控制受损。从机制上讲,B细胞内在的IL - 10信号对于维持生发中心反应是必需的。因此,我们的研究结果阐明了在持续性病毒感染期间,Tfh来源的IL - 10在促进体液免疫方面的关键作用。 在慢性感染期间,CD4⁺T细胞可逐渐获得产生IL - 10的功能。在此作者利用单细胞RNA测序技术在慢性感染的小鼠模型中探究IL - 10⁺CD4⁺T细胞群,并确定了产生Il10的Tfh参与促进抗病毒体液免疫反应。
During chronic viral infection, the inflammatory function of CD4 T-cells becomes gradually attenuated. Concurrently, Th1 cells progressively acquire the capacity to secrete the cytokine IL-10, a potent suppressor of antiviral T cell responses. To determine the transcriptional changes that underlie this adaption process, we applied a single-cell RNA-sequencing approach and assessed the heterogeneity of IL-10-expressing CD4 T-cells during chronic infection. Here we show an IL-10-producing population with a robust Tfh-signature. Using IL-10 and IL-21 double-reporter mice, we further demonstrate that IL-10+IL-21+co-producing Tfh cells arise predominantly during chronic but not acute LCMV infection. Importantly, depletion of IL-10+IL-21+co-producing CD4 T-cells or deletion of Il10 specifically in Tfh cells results in impaired humoral immunity and viral control. Mechanistically, B cell-intrinsic IL-10 signaling is required for sustaining germinal center reactions. Thus, our findings elucidate a critical role for Tfh-derived IL-10 in promoting humoral immunity during persistent viral infection. During chronic infection CD4+ T cells can progressively acquire IL-10 producing functionality. Here the authors use single cell RNA sequencing to interrogate the IL10 CD4+ T cell compartment in a murine model of chronic infection and identify Il10-producing Tfh involved in promotion of the antiviral humoral immune response.
