Project description:IL-10 is a prototypical anti-inflammatory cytokine, which is fundamental to the maintenance of immune homeostasis, especially in the intestine. There is an assumption that cells producing IL-10 have an immunoregulatory function. However, here we report that IL-10-producing CD4+ T cells are phenotypically and functionally heterogeneous. By combining single cell transcriptome and functional analyses, we identified a subpopulation of IL-10-producing Foxp3Neg CD4+ T cells that displays regulatory activity unlike other IL-10-producing CD4+ T cells, which are unexpectedly pro-inflammatory. The combinatorial expression of co-inhibitory receptors is sufficient to discriminate IL-10-producing CD4+ T cells with regulatory function from others and to identify them across different tissues and disease models in mice and humans. These regulatory IL-10-producing Foxp3Neg CD4+ T cells have a unique transcriptional program, which goes beyond the regulation of IL-10 expression. Finally, we found that patients with Inflammatory Bowel Disease (IBD), demonstrate a deficiency in this specific regulatory T-cell subpopulation.

Project description: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 T cell adaption process, we applied a single-cell RNA-sequencing approach and assessed the heterogeneity of IL-10-expressing CD4 T cells during chronic infection. Unexpectedly, our analyses revealed 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 resulted in impaired humoral immunity and viral control. Mechanistically, B cell-intrinsic IL-10 signaling was required for sustaining germinal center reactions. Lastly, we demonstrate that IL-27 and type I IFNs differentially regulate the formation of this protective IL-10-producing Tfh subset. Thus, our findings elucidate a critical role for Tfh-derived IL-10 in promoting humoral immunity during persistent viral infection.

Project description:Dengue virus (DENV) infection is associated with a range of clinical manifestations, from self-limiting dengue fever (DF) to life-threatening dengue hemorrhagic fever (DHF) and dengue shock syndrome (DSS). Although DENV-specific CD4 T cells are capable of producing inflammatory cytokines and can acquire cytotoxic functions in previously DENV-exposed individuals, much less is known related to DENV-specific CD4 T cells during acute DENV infection and disease. In this study, we set out to characterize the immune signatures of DENV-specific CD4 T cells during acute infection and investigate whether DENV-specific CD4 T cell response differs between DF and DHF. Previous studies suggest that increased IL-10 level in the blood is associated with severe dengue disease. Here we show evidence of DENV-specific IL-10-producing CD4 T cells during acute DENV infection. More specifically, an IL-10+IFN-γ+ double positive (DP) CD4 T cell population was prominent in acute hospitalized DENV cases but disappeared at the convalescent stage. RNA-sequencing analysis revealed that these cells were associated with gene signatures that marginally overlapped with previously identified signatures of cytotoxic CD4 T cells and type 1 regulatory T (Tr1)-like cells. However, the majority of the genes differentially expressed by DP cells were not related to cytotoxic CD4 T cells or Tr1-like cells. These genes include IL-21, IL-22, CD86, CD109, and CCR1, which are involved in T cell activation, function, cytokine signaling, and migration. Notably, the magnitude of DP cell response was higher in DHF than DF, whereas the gene expression profile of DP cells was similar between DF and DHF. Finally, our data show that DENV-specific DP cells are largely homogeneous based on the expression of 31 selected markers. Overall, this study reveals unique phenotypes of virus-specific IL-10/IFN-γ co-producing CD4 cells and indicates that the quantity but not quality of these cells may be positively correlated with dengue disease severity.
