Project description:We assessed the gene expression profile of purified CD205+CD8+ Dendritic Cells isolated from murine spleens. Mice were injected 5 days previously with B16 melanoma cells expressing recombinant FLT3L in order to boost CD205 DC populations

Project description:Analysis of gene expressions in mouse splenic dendritic cells (DCs). DCs were purified into two subsets, CD8-positive and -negative ones. DCs were expanded in vivo by injecting Flt3L-producing tumors into the backs of C57BL/6 mice.

Project description:Analysis of gene expressions in mouse splenic dendritic cells (DCs). DCs were purified into two subsets, CD8-positive and -negative ones. DCs were expanded in vivo by injecting Flt3L-producing tumors into the backs of C57BL/6 mice. To expand DCs in vivo, Flt3L-producing B16 melanoma cells were injected to the backs of mice. Then, 10-12 days later, splenic DCs were enriched by MACS and purified into CD3-B220-CD8a+CD11c+ and CD3-B220-CD8a-CD11c+ cells by FACS cell sorter.

Project description:The close functional relationship between macrophages and dendritic cells has long been recognised. Here, we have examined the gene expression profiles of splenic macrophages and the splenic resident dendritic cell subsets, and demostrate that macrophages and DC show different gene expression profiles. Further, we show that the DC subsets are closer to one another in gene expression profile than they are to macrophages. We here identify a list of differentially expressed genes between the DC subsets, and between DC and macrophages Splenic macrophages, CD8+ and CD8- cDC were analyzed

Project description:Background: Dendritic cells (DCs) are critical for regulating CD4 and CD8 T cell immunity, controlling Th1, Th2, and Th17 bias, generating inducible Tregs, and inducing tolerance. Multiple DC subsets have been identified in the mouse that are thought to have evolved to control these different immune outcomes. However, how these subsets differentially respond to inflammatory and/or tolerogenic signals in order to accomplish their divergent functionality remains unclear. Results: We analysed the responses of murine, splenic CD8 and CD11b DC subsets to in-vivo stimulation with lipopolysaccharide using RNA-Seq and systems biology approaches and observed responses are highly subset-specific. We reanalysed multiple datasets from the literature and show that these subset responses are obscured when analysing signaling at the population level. We show that the subset-specificity is due to the unique regulation of distinct TLR4 pathway modulators that ‘fine-tune’ a common TLR4 cascade rather and not due to major differences in signaling pathways or transcription factors. Conclusions: We propose the Pathway Modulation Model wherein common signaling pathways are regulated by unique sets of modulators allowing for distinct immune responses in closely related DC subsets. We extend these observations using analagous datasets from the literature and show that our model provides a global mechanism for generating cell subset-specific signaling in multiple subpopulations in mouse and man. Splenic CD8 and CD11b DC subsets from LPS stimulated (10 pooled animals) and Control (5 pooled animals) mice were analysed by RNA-Seq.

Project description:The functional relationships and properties of different sub-types of dendritic cells (DC) remain largely undefined. We used a global gene profiling approach to determine gene expression patterns among murine splenic CD11c high DC subsets in an effort to better characterise these cells. Keywords: equivalent probe

Project description:8-12 week, female C57BL/6 mice were injected with 10 µg/kg TCDD or solvent control. CD8+ T cells from spleen were FACS purified and submitted to transcription profiling Keywords: TCDD, AHR, Immunosupression peripheral T cells, CD8 T cells, Toxicogenomics For each group 4 female C57BL/6 mice were treated, spleen surgically removed and single cell suspensions generated. Cell suspensions were pooled, and CD8 positive T cells purified (purity > 99%). RNA was isolated using TRIzol and amplified using the Ambion message AMP kit. Target lableing and hybridization was performed using Affymetrix standard protocols

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
