Project description:Analysis of the role of LXR transcriptions factors on the transcriptional signature of human GM-CSF-dependent monocyte-derived macrophages. Methods: Human Peripheral Blood Mononuclear Cells (PBMC) were isolated from buffy coats from donors over a Lymphoprep gradient according to standard procedures. Monocytes were purified from PBMC by magnetic cell sorting using anti-CD14 microbeads (>95% CD14+ cells). Monocytes from three independent donors (0.5 x 106 cells/ml, >95% CD14+ cells) were treated with LXR agonist GW3965 (1 uM, Tocris), LXR antagonist GSK2033 (1 uM, Tocris), GW3965 and GSK2033, or dimethyl sulfoxide (DMSO) as vehicle. In the dual condition, the antagonist was added 1-hour prior to agonist treatment. Then, monocytes were cultured in RPMI 1640 supplemented with 10% fetal bovine serum (FBS) at 37°C in a humidified atmosphere with 5% CO2 and 21% O2 for 7 days in the presence of 1000 U/ml GM-CSF, with cytokine addition every two days.

Project description:As innate immune cells, monocytes play a central role in antifungal immunity. Using proteome studies in primary human monocytes, which were stimulated by Candida albicans (yeast) in vitro. Here we describe the changes of proteins in monocytes and demonstrate that in the early stage of infection, the differences of innate immune response triggered by C. albicans over time.

Project description:We found that human cord blood nucleated red blood cells (NRBCs) have a regulatory function in the innate immune reaction. NRBCs suppressed the production of inflammatory cytokines including TNF-a and IL-1b from monocytes in response to lipopolysaccharide (LPS). NRBCs exerted the regulatory function even without cell-to-cell contact with monocytes. On the other hand, IL-10 production from monocytes by the stimulation of LPS in the presence of NRBCs was higher than that of LPS-stimulated monocytes cultured in the absence of NRBCs. Addition of an anti-IL-10 receptor blocking antibody restored the inflammatory cytokine production from monocytes, suggesting that the functional change of monocytes caused by the interaction of NRBCs was characterized and mediated by the increased IL-10 production. Whole-genome microarray analysis revealed that monocytes expressed increased amounts of IL-10 superfamily genes after the interaction with NRBCs. IL-19, one of the IL-10 superfamily, enhanced IL-10 production from monocytes, which suggested cooperative role of IL-10 superfamily in the suppression of inflammatory cytokine production from monocytes. Arginase which was reported to play an important role in the suppressive function of NRBCs on monocytes in mice was found to play no significant role in human monocytes. NRBCs seem to have a regulatory role to suppress vigorous innate immune reaction which can be harmful to the fetuses via some unknown soluble factor which enhances the production of IL-10 and IL-10 family cytokines in monocytes.

Human LPS-stimulated monocytes were collected after culture in a condition without and with NRBCs in transwell culture system. Only one experiment was performed.

Project description:Macrophages are central mediators of the innate immune system that can be differentiated from monocytes upon exposure to cytokines. While increased cyclic adenosine monophosphate (cAMP) levels inhibit many lipopolysaccharide (LPS) -elicited macrophage inflammatory responses, the effects of elevated cAMP on macrophage differentiation are not well understood. We have differentiated monocytes to macrophages in the presence of GM-CSF or GM-CSF + FSK to elevate cAMP levels and determine its effects on differentiation.

Microarray analysis was performed separately on samples from 3 human donors: 3 control and 3 forskolin-treated samples.

Project description:Human and murine studies showed that granulocyte macrophage colony-stimulating factor (GM-CSF) exerts beneficial effects in intestinal inflammation. To explore whether GM-CSF mediates its effects via monocytes, we analyzed effects of GM-CSF on monocytes in vitro and assessed the immunomodulatory potential of GM-CSF-activated monocytes (GMaM). We used microarray technology and functional assays to characterize GMaM in vitro and used a mouse model of colitis to study GMaM functions in vivo. Peripheral blood monocytes where cultured 16 h with media containing AB serum (control monocytes) or media containing 10 ng/mL GM-CSF and AB serum (GM-CSF activated monocytes). In three independent experiments, total RNA from GMaM and control monocytes was isolated and processed for microarray hybridization.

Project description:Earlier work has shown that macrophages derived from differentiation of monocytes by heat killed (HK) mycobacteria (e.g. M. obuense) exhibit unique immunophenotypic and molecular properties. Yet, our knowledge of these properties is still limited. The goal of the study is to understand global gene expression programs that are differentially modulated in macrophages derived from monocytes that were differentiated through three different routes: in presence of M-CSF, GM-CSF and the heat killed mycobacterium M. obuense. We performed RNA sequencing (RNA-Seq) of monocyte-derived macrophages (MDM) that were acquired from four separate healthy donors and differentiated by incubation with M-CSF (M-MDM), GM-CSF (GM-MDM) and HK M. obuense (Mob-MDM) (n = 12 samples). We report that Mob-MDM exhibit unique gene expression programs that may explain its unique immunophenotypic properties and thus immunomodulatory capacity.
