The MYCL and MXD1 transcription factors regulate the fitness of murine dendritic cells

ABSTRACT: The present study reveals LMYC and MXD1 as novel regulators of a transcriptional program that is modulated during the maturation of Batf3-dependent dendritic cells (also known as type I classical dendritic cells or cDC1s). We used microarray analysis with ERCC spike in controls to determine the transcriptional effects of MYCL and MXD1 deficiency at steady state and after activation with poly IC. Mycl-deficient mice are available from Jackson laboratories as B6.129S6(C)-Mycltm1.1Kmm/J. Mxd1-/- mice were provided by R. Eisenman.

Cis-regulation between Irf8 enhancers during cDC1 development (CUT&RUN)

Project description:Type 1 classical dendritic cells (cDC1s) development requires the transcription factor IRF8, and IRF8 mutations cause severe combined immunodeficiency, including disseminated bacille Calmette-Guérin (BCG) disease. IRF8 regulated enhancers are required for Irf8 expression in early DC progenitors and mature cDC1s. The E-protein-dependent +41 kb enhancer gains accessibility and activates transcription in common DC progenitors (CDPs), and its depletion abrogated pre-cDC1s specification. The Batf3-dependent +32 kb enhancer gains accessibility and activates transcription in pre-cDC1 progenitors, and its depletion impaired cDC1 maturation. The +32 kb Irf8 enhancer locus bears an enhancer transcript, and the production of enhancer RNA (eRNA) Gm39266 is dependent on +41 kb Irf8 enhancer. It was unclear whether the +32 kb and +41 kb enhancers act independently or cooperate to regulate Irf8 expression. We dissected the mechanisms using +32/+41 compound heterozygous mice, and found that while the +41 kb enhancer suffices for pre-cDC1 progenitor specification, the +32 kb and +41 kb enhancers must reside on one allele to support cDC1 maturation. The +41 kb enhancer cis-regulates chromatin accessibility and BATF3 binding at +32 kb enhancer, independent of eRNA Gm39266 transcripts or transcription across +32 kb Irf8 enhancer.

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.

Batf3 maintains Irf8 autoactivation for commitment of a novel clonogenic progenitor of CD8+DCs

Project description:The transcription factors Batf3 and IRF8 are required for development of CD8α+ conventional dendritic cells (cDCs), but the basis for their actions was unclear. Here, we identify two novel Zbtb46+ progenitors that separately generate CD8α+ and CD4+ cDCs and arise directly from the common DC progenitor (CDP). Irf8 expression in the CDP depends on prior PU.1-dependent autoactivation, and specification of pre-CD8 DC progenitors requires IRF8 but not Batf3. However, upon pre-CD8 DC specification, Irf8 autoactivation becomes Batf3-dependent at a CD8α+ cDC-specific enhancer containing multiple AP1-IRF composite elements (AICEs) within the Irf8 superenhancer. CDPs from Batf3-/- mice that specify toward pre-CD8 DCs fail to complete CD8α+ cDC development due to decay of Irf8 autoactivation, and divert to the CD4+ cDC lineage.

Single-cell transcriptional profiling informs efficient reprogramming of human somatic cells to cross-presenting dendritic cells

Project description:Type-1 conventional dendritic cells (cDC1s) are rare immune cells critical for the induction of antigen-specific cytotoxic CD8+ T-cells. The genetic program driving human cDC1 specification remains largely unexplored. We have previously identified PU.1, IRF8 and BATF3 transcription factors as sufficient to induce cDC1 fate in mouse fibroblasts but reprogramming of human somatic cells was limited by low efficiencies. Here, we investigated single-cell transcriptional dynamics during human cDC1 reprogramming. Human induced cDC1s (hiDCs) generated from embryonic fibroblasts gradually acquire a global cDC1 transcriptional profile and activate antigen presentation signatures. Importantly, other DC subsets are not induced at the single-cell level. We extracted gene modules associated with successful reprogramming and identified inflammatory signaling and the cDC1-inducing transcription factor network as key drivers of the process. Combining IFN-γ, IFN-β and TNF-α with constitutive expression of cDC1-inducing transcription factors lead to improvement of reprogramming efficiency by 190-fold. hiDCs uptake dead cells, secrete inflammatory cytokines and perform antigen cross-presentation, a key cDC1 function. This approach allowed efficient hiDC1 generation from adult fibroblasts and mesenchymal stromal cells. Mechanistically, PU.1 shows dominant and independent chromatin targeting at early phases of reprogramming, recruiting IRF8 and BATF3 to shared binding sites. The cooperative binding at open enhancers and promoters leads to silencing of fibroblast genes and activation of a cDC1 program. These findings provide mechanistic insights into human cDC1 specification and reprogramming and represent a platform for generating patient-tailored cDC1s, a long-sought DC subset for vaccination strategies in cancer immunotherapy.

Genome-wide analysis of FcÎ³ receptor ligation on dendritic cells from wild-type, FcÎ³RIIb KO or FcR Î³ chain KO mice

Project description:Analysis of changes in gene expression after incubation of dendritic cells with immune complexes or medium. Since the dendritic cells are derived from three different mouse strains, either wild type, FcÎ³ receptor IIb KO (expresses only activating FcÎ³ receptors) or Fc receptor Î³ chain KO (expresses only inhibitory FcÎ³ receptor), the analysis gives important insight into the roles of the activating versus inhibiting FcÎ³ receptors on dendritic cells. Bone marrow-derived dendritic cells of the three mouse genotypes (see above) were incubated for 4 hours with medium (unstimulated) or OVA-anti OVA immune complexes (IC, stimulated) and changes in gene expression after stimulation with IC were compared between unstimulated vs stimulated with IC and across the three genotypes.
