Microarray analysis of WT and L-Myc-deficient DC subsets

ABSTRACT: Analysis of L-Myc-dependent genes in pDCs and classical DC subsets with and without stimulation. Splenocytes were harvested from C57BL/6 wild-type (WT) or 10 generation C57BL/6 backcrossed Mycl1-gfp/gfp (LmycKO) mice and DC subsets sorted to >95% purity on the FACSAriaII.

Microarray analysis of WT ESAM+ and ESAM- cDC subsets

Project description:Defense against attaching and effacing (A/E) bacteria requires the sequential generation of IL-23 and IL-22 to induce protective mucosal responses. While the critical source of IL-22 has been identified as CD4+ and Nkp46+ innate lymphoid cells (ILCs), the precise source of IL-23 is unclear. Here, we use genetic techniques to deplete specific classical dendritic cell (cDC) subsets and analyze immunity to the A/E pathogen Citrobacter rodentium. We find that Zbtb46+ cDCs, and specifically Notch2-dependent intestinal CD11b+ cDCs, but not Batf3-dependent CD103+ cDCs, are required for IL-23 production and immunity against C. rodentium. Notch2 controls cDC differentiation at a terminal step mediated by lymphotoxin signaling. Importantly, these results provide the first demonstration of a non-redundant function of CD11b+ cDCs in vivo. Analysis of differentially expressed genes in ESAM+ and ESAM- CD11b+ and DEC205+ splenic classical DC subsets. Splenocytes were harvested from WT C57Bl/6 or WT Cx3cr1-gfp mice and cDC subsets sorted to >95% purity on the FACSAriaII.

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. Examination of histone modifications (H3K27ac and H3K4me1) and 2 transcription factors (Batf3 and Irf8) and the p300 co-factor binding in 3 different dendritic cell subsets

Microarray analysis of WT bone marrow myeloid progenitors, BM cultured with GM-CSF and M-CSF, and monocytes treated with GM-CSF

Project description:Analysis of genes induced in DC precursors and in BM cells and monocytes treated with GM-CSF For progenitor arrays, bone marrow progenitors (CMP, GMP, CDP, and pre-cDC) were harvested from WT C57Bl/6 mice. For culture arrays, BM was cultured in the presence of GM-CSF or M-CSF and adherent and non-adherent cells sorted. For monocyte cultures, sorted BM monocytes were treated with GM-CSF for 0, 24 or 48 hours.

Expression data in splenic DC subsets in wild type and Xbp1 deficient mice

Project description:Xbp1 is a major transcription factor in the unfolded protein response. To uncover its function in DCs we generated a conditional KO for Xbp1 in dendritic cells. We here compare the expression of mRNAs in two different splenic DC subpopulations, CD8a and CD11b DCs in both WT and KO mice. Reference: Inositol-requiring enzyme 1-alpha regulates CD8a dendritic cell function via regulated mRNA decay. Osorio et al, Nature Immunology (2014) Primary DC subsets were isolated and sorted from spleens from 3 different WT or CD11c-cre Xbp-1fl/fl mice. RNA was isolated, converted to cDNA and then hybridised on Affymetrix GeneChip Mouse Gene 1.0 ST Arrays (GPL6246).

Expression data from in vitro derived dendritic cells generated in the presence of FLT3-L from wt and miR-142-/- BM cells

Project description:2 types of dendritic cells (DCs) can be generated in vitro in the presence of Flt3-L: CD4+ equivalent CD24- DCs and CD8+ equivalent CD24+ DCs. miR-142-/- mice show a severe defect in the generation of CD4+ equivalent CD24- DCs. To understand the underlying mechanism, RNA expression was analyzed by Affymetrix microarray from the 2 in vitro subtypes of DCs derived from miR-142+/+ and miR-142-/- bone marrow cells. We used microarrays to detail the global programme of gene expression in the presence or absence of miR-142 in in vitro derived DCs. Bone marrow cells from miR-142+/+ and miR-142-/- C57Bl/6 mice were isolated and incubated in the presence of Flt3-L for 8 days. in vitro derived wt and ko dendritic cells were devided into CD4+ and CD8+ equivalent DCs by FACS and sorted with a FACS-Aria. RNA was isolated and gene expression was investigated
