RNA-seq of small intestinal macrophages, neutrophils, CD103-CD11b+cDC and cryptopatch and ILF associated mononuclear phagocytes (CIA-MPh)

Project description:Cryptopatches (CP) and isolated lymphoid follicles (ILF) are evolutionary ancient lymphoid structures found in the intestines of all vertebrates. These structures are demarcated by a poorly characterised subset of mononuclear phagocytes (MPh), called CP/ILF-associated (CIA)-MPh. CIA-MPh expressed very high levels of lysozyme M (LysM), but they did not express Ly6G or CD64, normally associated with LysM-expressing neutrophils or macrophages, respectively. In order to understand the ontogeny and function of these newly identified MPh subset, we performed genome-wide transcriptional profiling of CIA-MPh and other cell types expressing LysM (i.e., neutrophils and macrophages) in the small intestine as well as of CD11b+ CD103- cDC2. Using Lyz2-GFP reporter mice, we developed a sorting strategy allowing us to highly purify neutrophils, macrophages, CD11b+ CD103- cDC2 and CIA-MPh. The RNA of each sample was extracted using the ImmGen protocol with phase lock tubes. The libraries were prepared using the SMARTer Ultra Low Input RNA kit (Clontech) according to the manufacturer’s instructions. The material was enriched for poly-A sequences and single-end Next Generation Sequencing was performed on a HiSeq 2500 machine (Illumina).

Mouse lung CD103+ and CD11b-high dendritic cell (DC) subsets

2010-03-15 | GSE17322 | GEO

Mouse lung CD103+ and CD11b-high dendritic cell (DC) subsets

Project description:Mouse lung CD11c+ dendritic cells are composed of 2 major DC subsets, the CD103+CD11b-low/intermediate DC (CD103+ DC) and the CD11b-highCD103- DC (CD11b-high DC). These 2 subsets are functionally distinct. Comparison of their functions showed CD103+ DC Microarray analysis was performed to compare the gene expression profiles of the 2 lung DC subsets in naÃ¯ve mice. Perfused lungs from 6-8-week naÃ¯ve BALB/cByJ mice were pooled and digested with collagenase D. CD11c+ cells were selected by anti-CD11c magnetic microbeads (Miltenyi) and stained by fluorochrome-conjugated mAb against I-A, CD103, CD11b, and CD11c plus 7-

RNA-seq analyses of two intestinal dendritic cell subsets, CD103+CD11b- and CD103-CD11b+, from wild type and CbfbF/F:CD11c-Cre mice.

Project description:We report phenotypes in gut dendritic cell development by loss of Runx/Cbfb transcription factor complexes. To further examine function of residual CD103+CD11b- and CD103-CD11b+ DCs, we performed RNA-seq analyses and compared gene expression signatures between control and Cbfb-deficient cells.

Expression profiling of murine E10.5 TLR2+ CD11b+ embryonic phagocytes by comparative microarray analyses

Project description:The detection of Toll-like receptor 2 (TLR2) expression on E10.5 early embryonic phagocytes prompted us to determine the list of markers co-expressed with TLR2 in a cell-type specific manner. Thus, a comparative expression profiling of cDNAs between murine E10.5 TLR2+ CD11b+ embryonic cells and TLR2+ CD11b+ peritoneal macrophages as well as between TLR2+ CD11b+ and TLR2- CD11b- embryonic cells were performed using Illumina arrays. Each pairwise comparison experiment was performed in triplicate. Our data identified several novel markers of early embryonic phagocytes that could be utilized for the isolation, manipulation and functional characterization of this poorly characterized cell population. In this context, Ferroportin1 (Slc40a1) was highly expressed on E10.5 phagocytes what suggests the critical contribution of these cells to the homeostasis of iron metabolism during embryonic development.

Activation and presentation of SIINFEKL:Kb by lung CD11b+ and CD103+ DCs after intranasal SIIN-Q11.

Project description:To investigate whether differentially expressed genes induced by SIIN-Q11 were shared between lung CD11b+ and CD103+ DCs, we performed gene expression profiling analysis of lung CD11b+ and CD103+ DCs after intranasal SIIN-Q11.

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.
