Project description:Dendritic cells (DC) are professional antigen presenting cells that develop from multipotent progenitors (MPP) and DC committed common DC progenitors (CDP) and further differentiate into different subsets: classical DC type 1 and 2 (cDC1 and cDC2, respectively) and plasmacytoid DC (pDC). In this study MPP, CDP, cDC1, cDC2 and pDC were obtained in a two-step in vitro culture system according to Felker et al., J. Immunol. 185, 5326-5335, 2010. Briefly, mouse bone marrow cells were first amplified with a specific cytokine cocktail and then induced to differentiate into DC with Flt3 ligand. MPP, CDP, cDC1, cDC2 and pDC were obtained by FACS sorting as follows: MPP: Gr1- CD117hi CD135low/-; CDP: Gr1- CD117int CD135+ CD115+; cDC1: CD11c+ CD11blow/- XCR1+; cDC2: CD11c+ CD11b+ XCR1- and pDC: CD11c+ CD11b- B220+. FACS sorted cells were then subjected to Omni-ATAC-seq, nuclear-titrated (NuTi) Capture-C targeting Irf8 promoter, and RNA-seq analysis. ATAC-seq data of cDC1 and pDC are published (Li et al., Genome Biol. 20, 45, 2019; GSE118221). ATAC-seq data of MPP, CDP and cDC2, NuTi Capture-C and RNA-seq data of MPP, CDP, cDC1, cDC2 and pDC are published here. CD11c+ CD11b+ B220- cDC and CD11c+ CD11b- B220+ pDC were obtained by FACS sorting and subjected to ChIP-seq analysis of IRF8 and are published here.

Project description:Analysis of the top differentially regulated genes in cDC1 in response to fucose treatment revealed genes enriched in pathways such as immune-effector processes, myeloid leukocyte activation, exocytosis, and secretion. We used microarrays to detail the global programme of gene expression underlying fucosylation deficiency in mouse cDC1 cells

Project description:The divergence of the common dendritic cell progenitor (CDP) into specified progenitors for the cDC1 and cDC2 dendritic cells subsets is poorly understood. Some transcription factors (TFs) act in commitment of already specified progenitors, such as Batf3 which stabilizes Irf8 autoactivation at the +32 kb Irf8 enhancer, but the mechanism of CDP divergence remains 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 has not revealed its mechanism or targets. Analysis of newly generated NFIL3 reporter mice showed extremely transient NFIL3 expression during cDC1 specification. CUT&RUN and ChIP-seq analysis identified endogenous NFIL3 binding in the –165 kb Zeb2 enhancer at three sites that also bind CCAAT-enhancer-binding proteins C/EBPa and C/EBPb. 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, respectively. Mutation of all three NFIL3/C/EBP sites ablated Zeb2 expression in myeloid, but not lymphoid progenitors, causing complete loss of pre-cDC2 specification and mature cDC2 development in vivo. These mice failed to generate TH2 responses against H. polygyrus infection, consistent with cDC2 supporting TH2 responses to helminths. Thus, CDP divergence is controlled by competition between NFIL3 and C/EBPs at the –165 kb Zeb2 enhancer.
