Immunity 20120712 1

Dendritic cell (DC)-mediated cross-presentation of exogenous antigens acquired in the periphery is critical for the initiation of CD8(+) T cell responses. Several DC subsets are described in human tissues but migratory cross-presenting DCs have not been isolated, despite their potential importance in immunity to pathogens, vaccines, and tumors and tolerance to self. Here, we identified a CD141(hi) DC present in human interstitial dermis, liver, and lung that was distinct from the majority of CD1 ...[more]

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.

Transcriptome profile of mouse lung dendritic cell subsets and macrophages.

Project description:Dendritic cell (DC) are critical initiators and regulators of immunity to pathogens, vaccines, tumors and tolerance to self. Mouse and human dendritic cells (DCs) are comprised of functionally specialized subsets, but precise interspecies correlation is currently incomplete and hampers the full translation of murine findings to human DC-based clinical therapies. In this study, we show that murine lung and gut lamina propria CD11b+ DC populations are comprised of two subsets: FLT3- and IRF4-dependent CD24+CD64- DCs and contaminating CSF-1R-dependent CD24-CD64+ macrophages. CD11b+CD24+CD64- DCs are instrumental in inducing Th17 cell immune response in the steady state and upon Aspergillus fumigatus challenge. We also identified human CD1c+CD11b+ DCs as the functional homologue of mouse mucosal CD11b+ DCs. Our findings highlight the conservation of key immune functions across species and aid the translation of murine studies to human DC immunobiology. The data for the associated human studies have been stored within GSE35459. Gene Expression from total RNA from specific mouse dendritic cell subsets purified by FACS

Transcriptome profile of human dermal macrophages and monocyte-derived macrophages

Project description:DC, monocyte and macrophage networks are evolutionarily conserved but the distinct subsets have been difficult to distinguish due to shared overlapping phenotypic markers between the cells. Using transcriptome microarray profiling of human and mouse mononuclear phagocyte subsets, we have distinguished human dermal DCs from monocyte-derived cells and macrophages.

Transcriptome analysis of blood monocytes from sepsis patients

Project description:Blood monocytes serve as the first line of host defense and are equipped to recognize and respond to infection by triggering an immune-inflammatory response. While most information on these cells comes from in vitro studies in humans or in vivo studies in mice, little is known about monocytes under human disease conditions. We investigated the role of monocytes during sepsis and its resolution in humans. A transcriptomal and functional analysis of blood monocytes from patients during gram negative sepsis and at recovery was performed. Monocytes from sepsis patients showed upregulation of a large number of pro-inflammatory genes and cytokines/chemokines, consistent with an ongoing systemic inflammation. However, these cells showed impairment to ex vivo endotoxin (LPS) challenge, displaying a quantitative decrease in the number of LPS-inducible genes. Moreover, they downregulated the expression of several pro-inflammatory cytokine/chemokine genes, activation marker genes and transcription factors associated with monocyte/macrophage activation, upon ex vivo LPS stimulation. Functionally, they downregulated expression of inflammatory cytokines/chemokines and antigen presentation-related molecules and functions. In contrast, genes and functions related to phagocytosis, anti-microbial activity and tissue remodeling where remained unaffected or even enhanced . Collectively, our observations suggest a genetic and functional re-programming of these cells during human sepsis progression. Understanding the molecular mechanisms which regulate this re-programming will allow to devise strategies which could modulate the response of these cells and hence, disease progression. Blood monocytes from gram-negative sepsis patients during sepsis (Sepsis) and following their recovery (Recovery/Basal) as well as healthy donor (control) were isolated. Thereafter, these cells were treated ex vivo with or without LPS for 3h and analysed for transcriptomic study.

Transcriptional and functional characterization of dendritic cell differentiation induced by CD137 ligand reverse signaling in human monocytes

Project description:The contribution of monocyte-derived dendritic cells (DC) to an immune response is essential for the elimination of pathogens. In vitro DC can be generated by treatment of monocytes with GM-CSF + IL-4 but it is unknown what stimuli induce the differentiation of monocytes to DC in vivo. CD137L-DC are human monocyte-derived DC that are generated by CD137 ligand (CD137L) signaling. Since CD137 is only expressed at sites of inflammation it would be a suitable signal for the induction of monocyte-derived DC. Here we report on gene expression analysis of CD137L-DC, immature and mature classical DC, monocytes and macrophages which indicates that CD137L-DC have a gene signature that is most similar to that of classical DC. Additionally, CD137L-DC signature genes are highly enriched in monocyte-derived DC which were isolated from sites of inflammation. Also cell surface marker expression and cytokine secretion of CD137L-DC are highly similar to that of inflammatory monocyte-derived DC. CD137L-DC express high levels of adhesion molecules, display strong attachment and employ the adhesion molecule ALCAM to stimulate T cell proliferation. This study identifies a physiological stimulus for the generation of monocyte-derived DC in vivo. A total of 30 expression profiles were obtained, on 6 APC subtypes from 5 different donors
