ChIP-chip by array of human monocytes, monocyte-derived macrophages and dendritic cells to measure the presence of histone H3, H3K4me3, H3K27me3 and AcH3

ABSTRACT: We have measured the presence of histone H3 and its modifications H3K4me3, H3K27me3 and AcH3 in the promoters of three different cell types: monocytes and monocyte derived macrophages and dendritic cells. The measurements were performed using Nimblegen 385K RefSeq Promoters array.

Transcription profiling of human monocytes from patients with dominant negative mutations in PPARg and rosiglitazone treated cells to investigate PPARg regulated gene expression in human dendritic cells

Project description:In order to gain insights into how PPARg regulates different facets of dendritic cell (DC) differentiation, we sought to identify PPARg regulated genes and gene networks in monocyte-derived dendritic cells using global gene expression profiling. We employed an exogenous ligand activation approach using a selective PPARg ligand (rosiglitazone abbreviated as RSG). In addition, we have defined culture conditions in which human serum (HS) induces PPARg activation via a yet uncharacterized endogenous mechanism. We also compared the gene expression profile of developing dendritic cells obtained from patients harboring dominant negative mutations of the PPARg receptor (C114R and C131Y). Experiment Overall Design: Monocytes were cultured for 6, 24 hours or 5 days with 500 U/ml IL-4 and 800 U/ml GM-CSF; cytokine treatment was repeated at day 3. Cells were obtained from 12 healthy individuals (6 biological replicates; the 6 and 24 hours samples were obtained from a single individual but the 5 days samples from a different one). Ligands were added at the beginning of differentiation. The 6 and 24 hours cells were treated with vehicle (DC) or 1 uM rosiglitazone (DC RSG), in the case of 5 day cultured cells 2.5 uM RSG was used. Cells were cultured in RPMI plus 10% FBS, in the case of DC4-DC6 cells were also cultured in human AB serum (DC HS). Finally we also obtained cells from patients harboring point mutations of the PPARg receptor (C114R and C131Y)

Interferon-gamma critically determines dendritic cell function

Project description:A growing body of evidence suggests that inflammatory cytokines have a dualistic role in immunity. In this study, we sought to determine the direct effects IFN-gamma on the differentiation and maturation of human peripheral blood monocyte-derived dendritic cells (moDC). Here, we report that following differentiation of human peripheral-blood monocytes into moDCs with granulocyte-macrophage colony-stimulating factor (GM-CSF) and IL-4, interferon-gamma (IFN-gamma) induces moDC maturation and up-regulates the co-stimulatory markers CD80, CD86, CD95, and MHC Class I, enabling moDCs to effectively generate antigen-specific CD4+ and CD8+ T cell responses for multiple viral and tumor antigens. Interestingly, early exposure of monocytes to high concentrations of IFN-gamma promotes monocyte differentiation into macrophages, despite the presence of GM-CSF and IL-4. However, under low concentrations of IFN-gamma, monocytes continue to differentiate into dendritic cells possessing a unique gene-expression profile, resulting in impairments in subsequent maturation by IFN-gamma and an inability to generate effective antigen-specific CD4+ and CD8+ T cell responses compared to standard moDCs. Monocytes differentiated in the presence of low levels of IFN-gamma downregulate IFN-gamma receptor expression, impairing their response to an inflammatory rechallenge. These findings demonstrate the ability of IFN-gamma to impart differential programs on human moDCs which shape the antigen-specific T cell responses they induce. Timing and intensity of exposure to IFN-gamma can thus determine whether moDCs are tolerogenic or immunostimulating. Human monocyte-derived dendritic cells from 4 healthy donors were differentiated with either GM-CSF and IL-4 (n=4) or GM-CSF, IL-4, and IFN-gamma (n=4). These samples were subsequently hybridized to arrays as 4 biological repeats for each of the two treatment conditions.

Proteomic analysis reveals core monocyte-derived cell differentiation proteome and highlights cellular identity-specific proteins

Project description:Monocytes can give rise to multiple highly specialized cell types to perform a wide array of functions, ranging from pathogen phagocytosis to bone resorption. This differentiation is induced by the binding of cytokines to dedicated receptors on the surface of monocytes, which results in the initiation of genetic programs that enable cells to perform their specialized functions. Given their common background, it is not surprising that monocyte-derived cells share abilities and cellular markers, yet their specialized functions require a dedicated set of proteins. In order to dissect the monocyte differentiation process and to define cell type-specific marker proteins, we differentiated circulating monocytes into dendritic cells, M1 and M2 macrophages, and osteoclasts, and assessed their proteomes by quantitative mass spectrometry throughout the differentiation process. Statistical analysis indicated that monocyte differentiation is a linear process characterized by a common core of proteins that is similarly affected among the distinct differentiation paths. Throughout the specialization process a cluster of RNA-binding and processing proteins was downregulated whereas proteins associated to metabolic processes were increased. Analysis of the specialized cells after 10 days of differentiation uncovered existing and putative novel dendritic cell markers. Combined, we here present a comprehensive proteomic analysis of monocyte differentiation uncovering shared and distinct proteomic features of differentiating monocytes and monocyte-derived cells.

Restricted Dendritic Cell and Monocyte Progenitors in Human Cord Blood and Bone Marrow

Project description:In mice, two restricted DC progenitors, macrophage-dendritic progenitor (MDP) and common dendritic cell progenitor (CDP) demonstrate increasing commitment of DC lineage as they sequentially lose granulocyte and monocyte potential respectively. Identifying these progenitors has enabled understanding of the role of DCs and monocytes in immunity and tolerance in mice. In humans, however, restricted monocyte and DC progenitors remain unknown. Progress in studying human DC development has been hampered by lack of an in vitro culture system that recapitulates in vivo DC hematopoiesis. Here we report a culture system that supports development of CD34+ hematopoietic stem cell progenitors into the three major human DC subsets, monocytes, granulocytes, NK and B cells. Using this culture system we defined the pathway for human DC development, and revealed the sequential origin of human DCs from increasingly restricted progenitors: a granulocyte-monocyte-DC progenitor (hGMDP) that develops into a monocyte-DC progenitor (hMDP) that develops into monocytes and a common DC progenitor (hCDP) that is restricted to produce the three major DC subsets. The phenotype of the DC progenitors partially overlaps with granulocyte monocyte progenitors (GMPs). These progenitors reside in human cord blood and bone marrow but not in the blood or lymphoid tissues in the steady state. We performed whole transcriptome expression analysis on monocytes and subsets of dendritic cells i.e. CD1c+ DCs, CD141+ DCs and CD303+ pDCs isolated from blood or differentiated in culture from cord blood CD34+ cells in presence of MS5 stromal cells and Flt3l, GM-CSF and SCF cytokines.

Gene expression profile of decidual macrophages and different in vitro M1 and M2 macrophage populations

Project description:Uterine (decidual) macrophages (M) are believed to play an important role in fetal tolerance during pregnancy, but the factors that regulate them are not known. In this study we investigated the potential role of several factors (M-CSF, GM-CSF, IL-4/13, IL-10, progesterone and estradiol) to drive the differentiation and polarization of human decidual M by using an in vitro M differentiation model. To estimate the similarity of the in vitro differentiated M with decidual M, we used the present gene expression array. The array consisted of 420 M-related genes, including 100 genes highly regulated in decidual M based on the gene expression profile previously reported (Gustafsson et al, 2008, PLoS ONE. 3(4): e2078). The analysis focused on the 100 decidual M-associated genes. Comparative expression analysis of CD14+ cells isolated from blood (3 samples) or decidua (3 samples) from pregnant women, CD14+ cells isolated from non-pregnant women (14 samples) and different types of in vitro-generated macrophages (55 samples). A total of 75 samples were anlayzed.
