Project description:Tolerogenic dendritic cells (DC) are key players in maintaining immunological homeostasis, dampening immune reactions, and promoting tolerance. DC-10, a tolerogenic population of human IL-10-producing DC characterized by the expression of HLA-G and ILT4, play a pivotal role in promoting tolerance via T regulatory type 1 (Tr1) cells. Thus far, the absence of specific biomarkers that uniquely identify DC-10 limited their studies in vivo. By gene expression profiling of in vitro differentiated human DC, we identified CD141 and CD163 as specific surface markers for DC-10. The co-expression of CD141 and CD163 in combination with CD14 and CD16 enables the ex vivo isolation of blood circulating DC-10. FACS-isolated CD14+CD16+CD141+CD163+ cells (ex vivo DC-10) from peripheral blood of healthy subjects produced spontaneously and upon activation IL-10 and limited levels of IL-12. Moreover, in vitro stimulation of allogeneic naive CD4+ T cells with ex vivo isolated CD14+CD16+CD141+CD163+ cells induced the differentiation of allo-specific Tr1 cells. Finally, ex vivo isolated CD14+CD16+CD141+CD163+ cells and in vitro differentiated DC-10 exhibited a similar transcriptional profile, characterized by anti-inflammatory and pro-tolerogenic signature. These results provide new insight into the DC-10 phenotype and on the role of circulating DC-10 in modulating T cell responses and promoting Tr1 cells. These findings open the opportunity to track DC-10 in vivo and to define their role in physiological and pathological settings.

Project description:To identify factors associated with the immunosuppressor activity of IL-10+ DC, these cells were obtained from VertX mice immunized with OVA+imiquimod and compared with IL-10- DCs from the same mice and from VertX mice, either untreated or vaccinated with OVA+poly(I:C).

Project description:Dendritic cells (DCs) uniquely direct the adaptive immune response towards activation or inhibition, yet little is known how these opposite programs are regulated at the transcriptional level. Here we applied genome-wide approaches to delineate the molecular function of DC-Specific transCRIPT (DC-SCRIPT/ZNF366), an 11 Zn finger-containing transcription factor potentiating DC-function by limiting IL-10 production. Transcriptome analysis identified DC-SCRIPT to affect expression of genes involved in MAPK signaling, and ChIP-Seq analysis showed binding of DC-SCRIPT to GA-rich enhancers nearby genes encoding MAPK Dual-Specificity Phosphatases (DUSPs). Functional studies demonstrated that DC-SCRIPT-knockdown DCs express much less DUSP4 and exhibit increased phosphorylation of all the three major MAPKs (ERK, JNK and p38). Enhanced ERK signaling in DC-SCRIPT-knockdown DCs led to higher production of the immune-inhibitory cytokine IL-10, which could be reverted by DUSP4 overexpression. These results delineate the molecular mechanism DC-SCRIPT employs to limit IL-10 production in DCs, thereby fine-tuning these professional antigen-presenting cells towards immune activation.

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.
