Microarray analysis of CD14+ CD163low cells in human intestinal lamina propria

Project description:Mouse intestinal innate immune cells have been identified as inducing Th17 cell differentiation. However, few studies have investigated innate immune cells that are involved in CD (Crohn's disiease) pathogenesis in humans. The present study aimed to identify a human intestinal lamina propria cell subset that induces Th17 cells, and to clarify its role in CD pathogenesis. Intestinal mucosa samples were obtained from patients who underwent resection of colorectal cancer or CD. Lamina propria cells (LPCs) were obtained by enzymatic digestion, and were analyzed for expression of HLA-DR, lineage markers (Lin), CD14, and CD163 using flow cytometry. Among HLA-DRhigh Lin- cells, we identified a CD14+ CD163low cell subset that was selectively present in intestinal LPCs. We identified CD14+ CD163low cells as having a potent capacity to induce Th17 cell differentiation in human intestinal lamina propria. The Th17-inducing activity of these cells was enhanced in CD patients. The Cy3-labeled cDNAs were hybridized on Agilent-039494 SurePrint G3 Human GE v2 8x60K Microarray (G4845A) in one color experiments, resulting in four individual microarrays.

Comparison of splenic and small intestine lamina propria dendritic cells

Project description: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 profiling of small intestine lamina propria dendritic cells

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.

Development of gene expression signatures for colonic lamina propria DCs of CD300a deficient mice

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

DNA methylation landscape and signature of CD4+ lymphocytes of lamina propria in Crohn's patients by reduced representation and bisulfite sequencing [BiSulfite-seq]

Project description:A genome-wide DNA methylation study was conducted using base resolution bisulfite sequencing for purified intestinal CD4+ cells (resected or biopsied mucosa of a terminal ileum) from 21 patients with Crohn’s disease and 12 age/sex matched controls. The sequencing data was analyzed for differentially methylated CpGs (DMCs) and differentially methylated regions (DMRs). Integration was performed with RNA-sequencing data for the same set of samples to verify the functional impact of DNA methylation changes.
