Gene expression profiles of mouse splenic macrophages and CD8+ and CD8- conventional dendritic cells

ABSTRACT: 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

Gene expression data of Peyer's patch conventional dendritic cells and macrophages at steady state and under TLR7 ligand stimulation

Project description:The initiation of the mucosal immune response in Peyer’s patch (PP) relies on the sampling, processing and efficient presentation of foreign antigens by dendritic cells (DC). PP DC encompass five subsets, among which CD11b+ conventional DC (cDC) and LysoDC have distinct progenitors and functions but share many cell surface markers. This has previously led to confusion between these two subsets. In addition, another PP DC subset, termed double-negative (DN), remains poorly characterized. Here, we have studied the genetic relatedness of the different subsets of PP cDC at steady state and under TLR7 ligand stimulation. We also provide the transcriptional profiles of subepithelial TIM-4- and interfollicular TIM-4+ macrophages.

In vivo LPS responses in murine splenic CD8 and CD11b DC subsets

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.

RNAseq of renal dendritic cells from adult Clec9a-Cre Rosa-YFP mice

Project description:We use bulk RNA sequencing of sorted cells to characterize the gene expression profiles of renal dendritic cell (DC) subsets, cDC1 and cDC2, as well as MHCII+CD64+ F4/80hi and MHCII+CD64+ CD11bhi cells. Splenic DCs and red pulp macrophages serve as reference populations for a macrophage-like or DC-like phenotype. By sorting YFP+/YFP- F4/80hi or YFP+/YFP- CD11bhi cells from Clec9a-Cre Rosa-YFP mice we aim to reveal transcriptional differences between YFP-labelled and unlabelled cells. We showed that F4/80hi cells resemble macrophages on a transcriptional level, despite their DC origin, and that renal CD11bhi cells are a transcriptionally unique subset. However, we were not able to reveal differences between YFP+ and YFP- populations.

Transcriptome profiles of mouse and human monocyte and dendritic cell subsets (human data)

Project description:Dendritic cells (DCs) are critical in mediating immunity to pathogens, vaccines, tumors and tolerance to self. Significant progress has been made in the study of DC subsets in murine models but the translation of these findings to human DC immunobiology has not been fully realized. Murine splenic CD8+ DC and CD103+ DC possess potent antigen cross-presenting capacity. Although recent evidence points to human blood CD141+ DCs as the functional equivalent of CD8+ DC, the precise identity of the human migratory cross-presenting DC has remained elusive. We performed phenotypic and functional analyses to interrogate the DC compartment of human non-lymphoid tissues and identified three distinct subsets: i) CD141high DCs, ii) CD1c DCs and iii) CD14+ DCs. Only CD141high DCs were capable of cross-presenting soluble antigen. Comparative transcriptome analysis of steady state monocyte and DC subsets between mouse and human confirmed conservation between species, aligning the following subsets together: i) human CD141high DCs with mouse CD8+ and CD103+ DCs, ii) human CD1c+ DCs with mouse CD4+ DCs and iii) human CD14+ DC with mouse monocyte subsets. The lack of positive association between human CD1c+ DCs and mouse non-lymphoid tissue CD11b+ DCs highlights heterogeneity and predicts the existence of a monocyte-like cell within the CD11b+ DCs. Gene expression analysis using total RNA from specific human and mouse monocyte and dendritic cell subsets purified by FACS.

Transcription profiling of different sub-types of mouse dendritic cells to study the functional relationships and properties of these cells.

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.

Alloantigen Infusion Selectively Activates the Transcriptome of Type 2 Conventional Dendritic Cells"

Project description:Recent studies have revealed novel molecular mechanisms by which innate monocytic cells acutely recognize and respond to alloantigen, and the significance of this to allograft rejection and immunologic tolerance. What remains unclear is the single cell heterogeneity of the innate allo-response, and particularly the contribution of dendritic cell (DC) subsets. To investigate the acute response of innate immune cells and DC subsets to exposure of alloantigen, experimental rodents were administered an intravenous injection of live allogenic cells versus isogenic cells. In parallel, we also infused apoptotic allogenic and isogenic cells, which have been reported to modulate immunity. Forty-eight hours after injection, recipient spleens were harvested, pooled by condition, enriched for DCs, and subjected to single cell mRNA sequencing and downstream analysis. Injection of live splenic cells induced a greater quantity of transcriptional changes across all DC subsets as identified by differential gene expression analysis and compared to apoptotic cell injection. In the setting of live cell infusion, type 2 conventional dendritic cells (cDC2s) were more transcriptionally responsive with a Ccr2+ cDC2 subcluster uniquely responding to the presence of alloantigen compared to isogenic control. Candidate receptors of allorecognition in other innate populations were interrogated amongst cDC2s and A-type paired immunoglobulin-like receptors (PIR-As) was found to be increased specifically in the cDC2 population following allo-exposure at the mRNA level and by flow cytometry. These results illuminate previously unclear distinctions between therapeutic infusions of live versus apoptotic allogenic cells and newly implicate cDC2 cells in innate allorecognition in the context of transplantation.
