Project description: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) from mice. Keywords: Lamina propria, DCs, cell type comparison We sought to determine the expression profile of small intestine lamina propria CD11c+ cells. RNA was extracted from DCs sorted from mouse small intestine (CD11c+CD11b- and CD11c+CD11b+ cells) and hybridized on Affymetrix microarrays.

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).

Project description:The intestinal immune system must elicit robust immunity against harmful pathogens but restrain immune responses directed against commensal microbes and dietary antigens. The mechanisms that maintain this dichotomy are poorly understood. Here we describe a population of CD11b+F4/80+CD11c– macrophages in the lamina propria (LP) that express several anti-inflammatory molecules including interleukin 10 (IL-10), but little or no pro-inflammatory cytokines, even upon stimulation with Toll-like receptor (TLR) ligands. These macrophages induced, in a manner dependent on IL-10, retinoic acid and exogenous transforming growth factor-β, differentiation of FoxP3+ regulatory T cells. In contrast, LP CD11b+ dendritic cells elicited IL-17 production. This IL-17 production was suppressed by LP macrophages, indicating that a dynamic interplay between these subsets may influence the balance between immune activation and tolerance. Splenic or small intestine lamina propria CD11b+11c- cells were isolated for RNA extraction and hybridization on Affymetrix microarrays. We sought to determine the unique genetic profile of small intestine lamina propria CD11b+11c- cells. Keywords: cell type comparison

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.

Project description:Several innate immune cell subsets have recently been identified to maintain gut homeostasis in both human and mice. Among these subsets, CX3CR1high CD11b+ CD11c+ cells contribute to intestinal tolerance through various mechanisms in mice. However, whether tolerogenic innate myeloid cells are present in the human intestine is not clearly defined. In this manuscript, we identified an intestinal myeloid cell subset possessing tolerogenic ability. HLA-DRhigh CD14+ CD163high cells in the human colon were divided into two subsets based on CD160 expression: CD163high CD160high and CD163high CD160low cells. Both cell subsets exhibited high levels of IL-10 production and high phagocytic activities. CD163high CD160high cells suppressed effector CD4+ T cell proliferation by a Foxp3+ Treg cell induction-independent mechanism. We further observed that the number and suppressive activity of these cells were profoundly decreased in patients with ulcerative colitis (UC). In addition, CD163high CD160high cells in the UC patients showed inflammatory phenotype, such as increased expression of IL6, CD80, and CD86, accompanied with decreased IL10RB expression. Our results highlight that a tolerogenic CD163high CD160high cell subset might be implicated in the prevention of UC development. Gene expression analysis of pooled lamina propria cells (LPCs) (n=12) and human blood CD14+ monocytes (n=7) were performed using Whole Human Genome Microarray Kit, 4x44K (G4112F) as one-color experiments.

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+).

Project description:To further development of our gene expression approach to CD300a deficiency on dendritic cells (DCs) in colonic lamina propria, we have employed whole genome microarray expression profiling as a discovery platform to identify genes with the potential to distinguish CD300a deficiency on DCs in colonic lamina propria from those of WT mice. Colonic lamina propria DCs were obtained by cell sorter from WT and CD300a deficient mice raised under SPF and GF condition. Expression of Ifnb1 was significantly higher in CD300a deficient DCs, quantified in the same RNA samples by real-time PCR. Gene expression in WT and CD300a colonic lamina propria DCs raised under SPF and GF conditions were measured. Colonic lamina propria cells were obtained from 5 mice in each conditions. Takara-Bio

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).
