Zeb2 regulates commitment to plasmacytoid dendritic cell and monocyte fate (part 2)

ABSTRACT: Recent studies have identified Zeb2 as a transcription factor important for the final maturation of natural killer cells and effector CD8+ T cells. We show that Zeb2 is required for the development of two myeloid cell types, the monocyte and the plasmacytoid dendritic cell, and clarify that this factor is not required for the development of classical dendritic cells.

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.

Transcription factor Zeb2 regulates commitment to plasmacytoid dendritic cell and monocyte fate.

Project description:Dendritic cells (DCs) and monocytes develop from a series of bone-marrow-resident progenitors in which lineage potential is regulated by distinct transcription factors. Zeb2 is an E-box-binding protein associated with epithelial-mesenchymal transition and is widely expressed among hematopoietic lineages. Previously, we observed that Zeb2 expression is differentially regulated in progenitors committed to classical DC (cDC) subsets in vivo. Using systems for inducible gene deletion, we uncover a requirement for Zeb2 in the development of Ly-6Chi monocytes but not neutrophils, and we show a corresponding requirement for Zeb2 in expression of the M-CSF receptor in the bone marrow. In addition, we confirm a requirement for Zeb2 in development of plasmacytoid DCs but find that Zeb2 is not required for cDC2 development. Instead, Zeb2 may act to repress cDC1 progenitor specification in the context of inflammatory signals.

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.

ZEB2 protects the heart from ischemic damage

Project description:infarct size and subsequent deterioration in function. The identification of factors that enhance cardiac repair by the restoration of the vascular network is, therefore, of great significance. Here, we show that the transcription factor Zinc finger E-box-binding homeobox 2 (ZEB2) is increased in stressed cardiomyocytes and induces a cardioprotective cross-talk between cardiomyocytes and endothelial cells to enhance angiogenesis after ischemia. Single-cell sequencing indicates ZEB2 to be enriched in injured cardiomyocytes. Cardiomyocyte-specific deletion of ZEB2 results in impaired cardiac contractility and infarct healing post-myocardial infarction (post-MI), while cardiomyocyte-specific ZEB2 overexpression improves cardiomyocyte survival and cardiac function. We identified Thymosin 4 (TMSB4) and Prothymosin (PTMA) as main paracrine factors released from cardiomyocytes to stimulate angiogenesis by enhancing endothelial cell migration, and whose regulation is validated in our in vivo models. Therapeutic delivery of ZEB2 to cardiomyocytes in the infarcted heart induces the expression of TMSB4 and PTMA, which enhances angiogenesis and prevents cardiac dysfunction. These findings reveal ZEB2 as a beneficial factor during ischemic injury, which may hold promise for the identification of new therapies.
