Expression data from WT cDC1s, Zeb2 KO cDC1s, Nfil3 Zeb2 DKO cDC1s and Zeb2 Id2 DKO cDC1s

ABSTRACT: We used microarrays to determine whether cDC1s from the two double KO are bona fide cDC1s, and what are the transcriptional changes within these cDC1s.

An Nfil3-Zeb2-Id2 pathway imposes Irf8 enhancer switching during cDC1 development.

Project description:Classical type 1 dendritic cells (cDC1s) are required for antiviral and antitumor immunity, which necessitates an understanding of their development. Development of the cDC1 progenitor requires an E-protein-dependent enhancer located 41 kilobases downstream of the transcription start site of the transcription factor Irf8 (+41-kb Irf8 enhancer), but its maturation instead requires the Batf3-dependent +32-kb Irf8 enhancer. To understand this switch, we performed single-cell RNA sequencing of the common dendritic cell progenitor (CDP) and identified a cluster of cells that expressed transcription factors that influence cDC1 development, such as Nfil3, Id2 and Zeb2. Genetic epistasis among these factors revealed that Nfil3 expression is required for the transition from Zeb2hi and Id2lo CDPs to Zeb2lo and Id2hi CDPs, which represent the earliest committed cDC1 progenitors. This genetic circuit blocks E-protein activity to exclude plasmacytoid dendritic cell potential and explains the switch in Irf8 enhancer usage during cDC1 development.

An Nfil3-Zeb2-Id2 pathway imposes Irf8 enhancer switching during cDC1 development (RNA-Seq)

Project description:Classical type 1 dendritic cells (cDC1s) are required for anti-viral and anti-tumor immunity, which has motivated a need to understand their development. The development of the cDC1 progentitor requires an E protein–dependent enhancer located 41 kilobases downstream of the transcription start site of the transcription factor IRF8 (+41 kb Irf8 enhancer) but its maturation instead requires the BATF3-dependent +32 kb Irf8 enhancer. To understand this switch, we performed single-cell RNA sequencing of the common dendritic cell progenitor (CDP) and identified a cluster of cells that expressed transcription factors that influence cDC1 development, such as Nfil3, Id2, and Zeb2. Genetic epistasis among these factors revealed that Nfil3 expression is required for the transition from Zeb2hi and Id2lo CDPs to Zeb2lo and Id2hi CDPs, which represent the earliest committed cDC1 progenitors. This genetic circuit blocks E protein activity to exclude plasmacytoid DC potential and explains the switch in Irf8 enhancer usage during cDC1 development.

Gene expression in WT, Flt3 KO, and Flt3L KO cDC1s and cDC2s

Project description:The goal of this study was to determine whether there are any gene expression changes in cDC1s and cDC2s from WT, Flt3 KO, or Flt3L KO mice. Specifically whether developing in the absence of Flt3 signaling had any effects on the gene expression of the cDCs

The transcription factor Zeb2 regulates development of conventional and plasmacytoid DCs by repressing Id2

Project description:Plasmacytoid dendritic cells (pDCs) develop from pre-pDCs, while two lineages of conventional DCs (cDC1s and cDC2s) develop from lineage-committed pre-cDCs. A number of transcription factors (TFs) have been implicated in regulating the development of pDCs (E2-2, Id2) and cDC1s (IRF8, Id2 and Batf3) however, those required for the early commitment of pre-cDCs towards the cDC2 lineage are unknown. Here we identified the TF Zinc finger E box binding homeobox 2 (Zeb2), to play a crucial role in regulating DC development. Zeb2 was expressed from the pre-pDC and pre-cDC stage onwards, and highly expressed in mature pDCs and cDC2s. Mice conditionally lacking Zeb2 in CD11c+ cells had a cell intrinsic reduction in pDCs and cDC2s, coupled with an increase in cDC1s. Conversely, mice in which CD11c+ cells overexpressed Zeb2 displayed a reduction in cDC1s. This was accompanied by altered expression of Id2, which was upregulated in cDC2s and pDCs from conditional knock-out mice. Zeb2 ChIP analysis revealed Id2 to be a direct target of Zeb2. Thus, we conclude that Zeb2 regulates commitment to both the cDC2 and pDC lineages through repression of Id2.

Erythropoietin receptor on cDC1s dictates immune tolerance

Project description:Immune tolerance is an active state of unresponsiveness of the immune system to antigens (Ags) that have the potential to induce an immune response1. Such tolerance is beneficial in avoiding autoimmunity and rejection of organ transplants, but detrimental in cancer2. Type 1 conventional dendritic cells (cDC1s) are unique in their efferocytosis3 and cross-presenting abilities4, resulting in T cell-mediated immunity5 or tolerance6-10. However, the mechanisms underlying the tolerogenic function of cDC1s remain largely unknown. Here, we show that the erythropoietin receptor (EpoR) acts as a critical switch that determines the tolerogenic state of cDC1s and the threshold of Ag-specific T cell responses. In total lymphoid irradiation-induced allograft tolerance11,12, EpoR+ cDC1s induce donor-specific CD4+FoxP3+ regulatory T cells (Tregs), and conditional knockout of EpoR in cDC1s abrogates Ag-specific Treg induction, resulting in allograft rejection. In the steady state, EpoR+ migratory cDC1s control Ag-specific Treg induction in peripheral lymph nodes (LNs). In cancer, EpoR is expressed on both tumor Ag-carrying, tumor-infiltrating cDC1s, as well as migratory cDC1s in tumor-draining LNs (tdLNs). Loss of EpoR from cDC1s leads to tumor reduction by enhancing tumor Ag-specific CD8+ T cell priming and generating more precursor exhausted T cells13 in tdLNs, preserving CD8+ T cell precursor-like features and effector function, and reducing Tregs in the tumor. Thus, targeting EpoR on cDC1s to induce or inhibit immune tolerance should enable new ways to treat a variety of diseases.
