(Submitter supplied) E protein transcription factors specify major immune cell lineages including lymphocytes and interferon-producing plasmacytoid dendritic cells (pDCs). Corepressors of the ETO family can bind to and block transactivation by E proteins, but the physiological role of these interactions remained unclear. We report that ETO protein Mtg16 binds chromatin primarily through the pDC-specific E protein E2-2 in human pDCs. more...

(Submitter supplied) 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. more...

(Submitter supplied) Dendritic cells (DCs) in lymphoid tissue comprise conventional DCs (cDCs) and plasmacytoid DCs (pDCs) that develop from common DC progenitors (CDPs). CDPs are Flt3+c-kitintM-CSFR+ and reside in bone marrow. Here we describe a two-step culture system that recapitulates DC development from c-kithiFlt3-/lo multipotent progenitors (MPPs) into CDPs and further into cDC and pDC subsets. MPPs and CDPs are amplified in vitro with Flt3 ligand, stem cell factor, hyper-IL-6 and insulin- like growth factor-1. more...

(Submitter supplied) The plasmacytoid dendritic cell (pDC) is vital to the coordinated action of innate and adaptive immunity. pDC development has not been unequivocally traced, nor has its transcriptional regulatory network been fully clarified. Here we confirm an essential requirement for the BCL11A transcription factor in fetal pDC development, and demonstrate this lineage-specific requirement in the adult organism. Furthermore, we identify BCL11A gene targets and provide a molecular mechanism for its action in pDC commitment. Embryonic germ-line deletion of Bcl11a revealed an absolute cellular, molecular, and functional absence of pDCs in fetal mice. In adults, deletion of Bcl11a in hematopoietic stem cells resulted in perturbed yet continued generation of progenitors, loss of downstream pDC and B-cell lineages, and persisting myeloid, conventional dendritic, and T-cell lineages. Challenge with virus resulted in a marked reduction of antiviral response in conditionally deleted adults. Genome-wide analyses of BCL11A DNA binding and expression revealed that BCL11A regulates transcription of E2-2 and other pDC differentiation modulators, including ID2 and MTG16. Our results identify BCL11A as an essential, lineage- specific factor that regulates pDC development, supporting a model wherein differentiation into pDCs represents a primed "default" pathway for common dendritic cell progenitors.

(Submitter supplied) Dendritic cells (DCs) are can be broadly divided into conventional (cDC) and plasmacytoid (pDC) subsets. Despite the importance of this lineage diversity, its genetic basis is not fully understood. ChIP-seq profiling of PU.1 binding sites in cDCs and pDCs revealed a key role for PU.1 in maintaining cDC identity.

Despite the importance of this lineage diversity, its genetic basis is not fully understood. RNA-seq gene expression analysis of wild type (WT) and PU.1 transgenic mice revealed a key role for PU.1 in maintaining cDC identity.

(Submitter supplied) Plasmacytoid dendritic cells (pDCs) rapidly produce type I interferon (IFN-I) in response to viruses and are essential for antiviral immune responses. Although related to classical dendritic cells (cDCs) in their development and expression profile, pDCs possess many distinct features. Unlike cDCs, pDCs develop in the bone marrow (BM) and emerge into peripheral lymphoid organs and tissues as fully differentiated cells. more...

(Submitter supplied) The interferon-producing plasmacytoid dendritic cells (PDC) share common progenitors with antigen-presenting classical dendritic cells (cDC), yet they possess distinct morphology and molecular features resembling those of lymphocytes. It is unclear whether the unique cell fate of PDC is actively maintained in the steady state. We report that the deletion of transcription factor E2-2 from mature peripheral PDC caused their spontaneous differentiation into cells with cDC properties. more...

(Submitter supplied) 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. more...
