Gene expression of distinct lung dendritic cell subsets

ABSTRACT: Pulmonary dendritic cells are heterogenous cells comprise four distinct subsets including two conventional dendritic cell subsets, CD103+ and CD11bhiCD14lo cells, and two monocyte-derived dendritic cell subsets. Their functions in terms of migration and T cell activation are distinct, but genes regulating their features are to be determined. We used microarrays to identify a select set of genes that are expressed in conventinal dendritic cells and in monocyte-derived dendriti cells. Four distinct lung DC subsets were purified by flow cytometry-based sorting after inhalation of lipopolusaccharide and ovalbumin. Each subset has three replicates.

Differential display of the integrins CD103 and CD11b are widely used to distinguish two major dendritic cell (DC) subsets in nonlymphoid tissues. CD103(+) DCs arise from FLT3-dependent DC precursors (preDCs), whereas CD11b(hi) DCs can arise either from preDCs or FLT3-independent monocytes. Functional characterization of these two lineages of CD11b(hi) DCs has been hindered by the lack of a widely applicable method to distinguish between them. We performed gene expression analysis of fractionate ...[more]

Expression data from subsets of mouse spleen dendritic cells

Project description:Mouse splenic dendritic cells are divided into different subsets based on their phynotype. CD8Î±+ and CD8Î±- dendritic cells play different roles against pathogens. Cross-presentation is essential for immune defense against viruses, tumors and intracellular bacteria and CD8Î±+ DCs are more potent in cross-presentation compared to CD8Î±- DCs. We used microarrays to detail the global gene expression to analyze the underlying mechanism in CD8Î±+ dendritic cells cross-presentation Splenic CD8Î±+ and CD8Î±- dendritic cells were sorted by flow-cytometer for RNA extraction and hybridization on Affymetrix microarrays. Thirty C57BL/6J mice were sacrified for the splenic cells, splenic DCs were enriched by negtive selection, then CD8Î±+ and CD8Î±- dendritic cells were seprated based on CD11c and CD8Î± markers.

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.

Comparison of gene expression profiles between human and mouse monocyte subsets [human data]

Project description:Human and mouse blood each contain two monocyte subsets. Here, we investigated the extent of their similarity using a microarray approach. Approximately 300 genes in human and 550 genes in mouse were differentially expressed between subsets. More than 130 of these gene expression differences were conserved between mouse and human monocyte subsets. We confirmed numerous differences at the cell surface protein level. Despite overall conservation, some molecules were conversely expressed between the two speciesM-bM-^@M-^Y subsets, including CD36, CD9, and TREM-1. Furthermore, other differences existed, including a prominent PPARM-NM-3 signature in mouse monocytes absent in human. Overall, human and mouse monocyte subsets are far more broadly conserved than currently recognized. Thus, studies in mice may indeed yield relevant information regarding the biology of human monocyte subsets. However, differences between the species deserve consideration in models of human disease studied in the mouse. Keywords: Expression profiling by array The two major subsets of monocytes (Ly-6C+ and Ly-6Clo) from 12-week old C57Bl/6 mice were sorted and the RNA extracted and hybridized to Affymetrix GeneChipM-BM-. 430 2.0 arrays. We pooled leukocytes from 5 mice for each sort and sorted 4 separate times for 4 biological replicates. The two major monocyte subsets (CD16- and CD16+) were isolated from venous heparinized blood from apparently healthy human volunteers using MACS technology with all reagents and tools from Miltenyi Biotec. Three separate donors were hybridized three different times to Affymetrix U133 Plus 2.0 array.

Affymetrix gene expression of Transitional Type-1 B-cells from Wild-type (CBA), Xid and Btk KO mice

Project description:Splenic Transitional Type-1 B-cells from CBA wild-type mice, X-linked immunodeficiency mice and Bruton's tyrosine kinase knock-out mice. Two replicates where run on Affymetrix 420 2.0 arrays for CBA wild-type, Xid samples and the Btk KO samples. Bruton's tyrosine kinase (Btk) is a cytoplasmic tyrosine kinase important for B-lymphocyte maturation. Mutations in Btk give rise to the primary immunodeficiency disease X-linked agammaglobulinemia (XLA) in man and X-linked immunodeficiency (Xid) in mice. Recent studies have subdivided the mouse immature, or transitional, B-cells into two distinct subsets according to their respective surface markers. Transitional type 1 (T1) and transitional type 2 (T2) cells are also located in distinct anatomic locations. Based on a limited number of markers it has previously been reported that the earliest phenotypic sign of Btk deficiency is manifested at the T2 stage in mice. Here, we report on distinct genome-wide transcriptomic signature differences found in T1 B-lymphocytes from Btk-defective compared to normal mice and demonstrate that Btk deficiency is visible already at this stage. 2 replicates of T1 B-cells from CBA (WT), Xid samples and the Btk KO samples

Antigen presenting cells of myeloid origin

Project description:Transcriptional profiles of four different myeloid antigen presenting cell (APC) subsets (BDCA-1+ circulating myeloid dendritic cells, CD14+ monocytes, and in vitro generated immature and mature monocyte-derived dendritic cells) were used for comprehensive transcriptome analysis. Based on the gene expression profiling data, a quantitative relationship between myeloid APC in functionally related gene spaces was established.

Polypropylene mesh implantation for hernia repair triggers myeloid cell-dependent persistent inflammatory foreign body reaction

Project description:Polypropylene meshes that are commonly used for surgical groin hernia repair may trigger granulomatous foreign body reactions. Here, we show that asymptomatic patients display mesh-associated inflammatory granulomas long after surgery, which are dominated by monocyte-derived macrophages. In mice, subdermal mesh implantation induces a rapid and strong myeloid cell accumulation, without substantial attenuation for up to 90 days. Myeloid cells segregate into distinct macrophage subsets with separate spatial distribution, activation profiles and functional properties. Protein mass spectrometry confirms the inflammatory nature of the foreign body reaction, as characterized by cytokines, complement activation and immunoglobulin deposition.
