Irf8 deficiency induces functional, transcriptional and epigenetic reprogramming of cDC1 into the cDC2 lineage

Project description:Conventional dendritic cells (cDC) consist of two functionally and phenotypically distinct subsets, cDC1 and cDC2, whose development is dependent on distinct sets of transcription factors. Interferon regulatory factor 8 (IRF8) is required at multiple stages of cDC1 development, but its role in mature cDC1 remains unclear. Here we used XCR1-cre to delete Irf8 in committed cDC1 and demonstrate that Irf8 is required for maintaining the identify of cDC1 but not their survival. In the absence of Irf8, committed cDC1 (“ex-cDC1”) acquired the transcriptional, functional and chromatin accessibility properties of cDC2. This conversion was independent on Irf4 and was associated with decreased accessibility in putative IRF8, Batf3 and composite AP-1-IRF (AICE) binding elements, together with increased accessibility of cDC2 associated transcription factor binding elements. Thus, IRF8 expression by committed cDC1 is required for preventing their conversion into cDC2.

RNA-seq analysis of mouse cDC1 and cDC2 populations upon DC-SCRIPT depletion

Project description:The functional diversification of dendritic cells (DCs) is a key step in establishing protective immune responses. Despite the importance of this lineage diversity, its genetic basis is not fully understood. DC-SCRIPT (Zfp366) is a poorly known transcription factor expressed in conventional DCs (cDCs) and their committed bone marrow progenitors but not in plasmacytoid DCs (pDCs). We show that mice lacking DC-SCRIPT displayed substantially impaired development of IRF8-dependent conventional DC1 (cDC1), while cDC2 differentiated normally. The residual DC-SCRIPT-deficient cDC1s had impaired CD8+ T-cell cross-priming, which could be in part explained by the direct control of DC-SCRIPT on IL-12p40 production. Genome-wide mapping of DC-SCRIPT binding and gene expression analyses revealed a key role for DC-SCRIPT in maintaining cDC1 identity via the direct regulation of cDC1 signature genes, including Irf8. Our study reveals DC-SCRIPT to be a critical component of the gene regulatory program shaping the functional attributes of cDC1s.

RNA-seq of lung myeloid cells from WT and Ptgs2-cKO mice

Project description:To investigate the role of the COX-2-dependent lung fibroblast program in reprogramming lung myeloid cells, we generated fibroblast-targeted Ptgs2 conditional knockout mice by crossing Pdgfra-Cre mice with Ptgs2flox/flox mice. Then we isolated two primary types of lung resident DCs-CD103+ conventional DC (cDC1) and CD11b+ conventional DC (cDC2), and lung monocytes from WT and Ptgs2 cKO mice by fluorescence-activated cell sorting and performed RNA sequencing.

Ablation of cDC2 development by triple mutations within the Zeb2 enhancer

Project description:The divergence of the common dendritic cell progenitor (CDP) into the conventional type 1 and type 2 dendritic cell (cDC1 and cDC2, respectively) lineages is poorly understood. Some transcription factors act in the commitment of already specified progenitors-such as BATF3, which stabilizes Irf8 autoactivation at the +32 kb Irf8 enhancer-but the mechanisms controlling the initial divergence of CDPs remain unknown. Here we report the transcriptional basis of CDP divergence and describe the first requirements for pre-cDC2 specification. Genetic epistasis analysis suggested that Nfil3 acts upstream of Id2, Batf3 and Zeb2 in cDC1 development but did not reveal its mechanism or targets. Analysis of newly generated NFIL3 reporter mice showed extremely transient NFIL3 expression during cDC1 specification. CUT&RUN and chromatin immunoprecipitation followed by sequencing identified endogenous NFIL3 binding in the -165 kb Zeb2 enhancer at three sites that also bind the CCAAT-enhancer-binding proteins C/EBPα and C/EBPβ. In vivo mutational analysis using CRISPR-Cas9 targeting showed that these NFIL3-C/EBP sites are functionally redundant, with C/EBPs supporting and NFIL3 repressing Zeb2 expression at these sites. A triple mutation of all three NFIL3-C/EBP sites ablated Zeb2 expression in myeloid, but not lymphoid progenitors, causing the complete loss of pre-cDC2 specification and mature cDC2 development in vivo. These mice did not generate T helper 2 (TH2) cell responses against Heligmosomoides polygyrus infection, consistent with cDC2 supporting TH2 responses to helminths. Thus, CDP divergence into cDC1 or cDC2 is controlled by competition between NFIL3 and C/EBPs at the -165 kb Zeb2 enhancer.
