Comparison of splenic and small intestine lamina propria dendritic cells

ABSTRACT: This SuperSeries is composed of the following subset Series: GSE22127: Expression profiling of small intestine lamina propria dendritic cells GSE22128: Expression profiling of splenic dendritic cells Dendritic cells play a vital role in initiating robust immunity against pathogens as well as maintaining immunological tolerance to self antigens, food antigens and intestinal commensals. However, the intracellular signaling networks that program DCs to become tolerogenic are largely unknown. To address this, we analyzed gene expression profiles using microarray analysis of purified intestinal lamina propria DCs (CD11c+ CD11b+ DCs and CD11c+ CD11b- DCs) and compared it to splenic DCs (CD11c+ DC), from mice. We sought to determine the unique genetic profile of small intestine lamina propria CD11c+ cells compared to splenic CD11c+ cells. We performed a meta-analysis using the expression profiles of Intestinal lamina propria CD11c+ CD11b+ DCs (GSM550122), Intestinal lamina propria CD11c+ CD11b- DCs (GSM550121) and Splenic CD11c+ DCs (GSM550126). This study combined and re-normalized the microarray data from GSE22127 and GSE22128 studies. Refer to individual Series for additional details

Expression of Spi-C in intestinal CX3CR1high macrophages

Project description:In murine large intestinal lamina propria, CX3CR1high resident Mfs possess anti-inflammatory properties and thereby support intestinal homeostasis. Unlike other tissue-resident MΦs, transcription factors that regulate differentiation and function of CX3CR1high MΦs in the large intestine are poorly understood. Thus, to identify transcription factors specifically expressed in CX3CR1high MΦs among large intestinal lamina propria innate myeloid cells, we comprehensively analyzed the genes expression profiles in CX3CR1high MΦs, CX3CR1- CD11b+ CD11c+ cells, CD11b- CD11chigh DCs, and CD11b+CD11c- cells. CD11b- CD11chigh DCs, expressing CD103, in the colon highly expressed transcription factors Batf3, Irf8, and Zbtb46, which have been reported to be required for development of CD103+ DCs. Among four subsets, CX3CR1high macrophages showed the highest expression level of Spic. Transcription factor Spi-C has been reported to be crucial for development of splenic RPMΦs and a fraction of BMMΦs, and thereby contributes to iron recycling.

RNA was extracted from DCs sorted from mouse spleen (CD11c+ cells) and hybridized on Affymetrix microarrays.

Notch2 receptor signaling controls functional differentiation of dendritic cells in the spleen and intestine

Project description:Dendritic cells (DCs) in tissues and lymphoid organs comprise distinct functional subsets that differentiate in situ from circulating progenitors. Tissue-specific signals that regulate DC subset differentiation are poorly understood. We report that DC-specific deletion of the Notch2 receptor caused a reduction of DC populations in the spleen. Within the splenic CD11b+ DCs, Notch signaling blockade ablated a distinct population marked by high expression of adhesion molecule Esam. The Notch-dependent Esamhi DC subset also required lymphotoxin beta receptor signaling, proliferated in situ and facilitated efficient CD4+ T cell priming. The Notch-independent Esamlo DCs expressed monocyte-related genes and showed superior cytokine responses. In addition, Notch2 deletion led to the loss of CD11b+ CD103+ DCs in the intestinal lamina propria and to the corresponding decrease of IL-17-producing CD4+ T cells in the intestine. Thus,Notch2 is a common differentiation signal for T cell-priming CD11b+ DC subsets in the spleen and intestine. We compared genome-wide expression profiles of wild-type Esam(hi) and Esam(lo) splenic CD11b+ DC populations, along with CD11b+ DCs from DC-RBPJΔ mice. Spleens from 2-3 Cx3cr1-GFP+ RBPJflox/flox CD11c-Cre+ mice or Cx3cr1-GFP+ RBPJflox/flox Cre-negative littermate controls were isolated, pooled and depleted of lymphoid and erythroid cells by negative selection on MACS columns. Live cells were stained for surface expression of CD11c, CD11b and Esam. CD11c(hi) CD11b+ DCs from control mice could be separated into Esam(lo) GFP(hi) versus Esam(hi) GFP(lo) subsets. CD11c(hi) CD11b+ DCs from RBPJ-targeted mice spleens were uniformly Esam(lo) GFP(hi). The two subsets from control mice and single Esam(lo) GFP(hi) subset from RBPJ-targeted mice were sorted using FACSAria II flow sorter and analyzed using GeneChip Mouse Gene 1.0 ST Array (Affymetrix).

Inflammation switches the differentiation program of Ly6Chi monocytes from anti-inflammatory macrophages to inflammatory dendritic cells in the colon

Project description:Dendritic cells (DCs) and macrophages (MPs) are important for immunological homeostasis in the colon. We found that F4/80hi CX3CR1hi (CD11b+CD103-) cells account for 80% of mouse colonic lamina propria (cLP) MHC-IIhi cells. Both CD11c+ and CD11c- cells within this population were identified as MPs based on multiple criteria, including a MP transcriptome revealed by microarray analysis. These MPs constitutively released high levels of IL-10 at least partially in response to the microbiota via an MyD88-independent mechanism. In contrast, cells expressing low to intermediate levels of F4/80 and CX3CR1 were identified as DCs, based on phenotypic and functional analysis and comprise three separate CD11chi cell populations: CD103+CX3CR1-CD11b- DCs, CD103+CX3CR1-CD11b+ DCs and CD103-CX3CR1intCD11b+ DCs. In non-inflammatory conditions, Ly6Chi monocytes differentiated primarily into CD11c+, but not CD11c- MPs. In contrast, during colitis, Ly6Chi monocytes massively invaded the colon and differentiated into pro-inflammatory CD103-CX3CR1intCD11b+ DCs, which produced high levels of IL-12, IL-23, iNOS and TNF. These findings demonstrate the dual capacity of Ly6Chi blood monocytes to differentiate into either regulatory MPs or inflammatory DCs in the colon, and that the balance of these immunologically antagonistic cell types is dictated by microenvironmental conditions.

Microarray analysis of WT and Notch2-deficient classical DC 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 Notch2-dependent genes in CD11b+ and DEC205+ splenic classical DC subsets. Splenocytes were harvested from littermate WT Notch2 f/f C57Bl/6 or Notch2 CD11c-cre C57Bl/6 mice and DC subsets sorted to >95% purity on the FACSAriaII.

Expression data from small intestinal eosinophils and dendritic cells

Project description:Under steady-state conditions, eosinophils are abundantly found in the small intestinal lamina propria, but their physiological function is largely unexplored. We performed a global gene expression analysis to examine which genes are highly expressed by small intestinal eosinophils (CD11b+CD11c(int)MHCII-SiglecF+) compared with dendritic cells (CD11c+MHCII+).

Expression data from subsets of mouse spleen dendritic cells

Project description:Mouse splenic dendritic cells are divided into different subsets based on their phynotype. CD8Î±+ and CD8Î±- dendritic cells play different roles against pathogens. Cross-presentation is essential for immune defense against viruses, tumors and intracellular bacteria and CD8Î±+ DCs are more potent in cross-presentation compared to CD8Î±- DCs. We used microarrays to detail the global gene expression to analyze the underlying mechanism in CD8Î±+ dendritic cells cross-presentation Splenic CD8Î±+ and CD8Î±- dendritic cells were sorted by flow-cytometer for RNA extraction and hybridization on Affymetrix microarrays. Thirty C57BL/6J mice were sacrified for the splenic cells, splenic DCs were enriched by negtive selection, then CD8Î±+ and CD8Î±- dendritic cells were seprated based on CD11c and CD8Î± markers.
