Project description:IL-4 and IL-13 are cytokines involved in type 2 immune responses involved in atopic asthma and other diseases. They have a partially overlapping set of cognate receptors whose roles are incompletely understood. Here we explore the effects of blocking one or both subunits of the IL-13 alpha receptor on the action of these cytokines on IMR-90 lung fibroblast cells. IMR-90 lung fibroblast cells were cultured on matrigel and treated with various combinations of IL-4 (10 ng/ml), IL-13 (10ng/ml), 228 B/C (which blocks signaling from IL13RA1), and 11H4 (which blocks signaling from IL13RA1 and IL13RA2).

Project description:IL-4 and IL-13 are cytokines involved in type 2 immune responses involved in atopic asthma and other diseases. They have a partially overlapping set of cognate receptors whose roles are incompletely understood. Here we explore the effects of these cytokines on lung fibroblasts in order to assess the global similarities and contrasts in the genes whose expression their ligation modulates. IMR-90 lung fibroblast cells were cultured on matrigel or plastic and treated for 24 hours with IL-4 (10 ng/ml), IL-13 (10ng/ml), or TNFa (10 ng/ml) before harvest.

Project description:Human CD14 positive monocytes were purified from healthy volunteers' blood and were differentiated to immature dendritic cells in vitro by culturing for five days in the presence of interleukin-4 (IL-4 100 ng/ml) and GM-CSF (75 ng/ml). Immature dendritic cells were activated three different ways for 24 hours: 1. Double-stranded DNA poly(dA:dT) (2.5 μg/ml) complexed with LyoVec transfection reagent. 2. LPS (500 ng/ml) 3. Inflammatory cocktail containing 10 ng/ml TNF, 5 ng/ml IL-1β, 20 ng/ml IL-6, 75 ng/ml GM-CSF and 1 μg/ml PGE2. We used SA Biosciences Antigen Presenting and Toll-like Receptor Pathway PCR Arrays to quantitate gene expression of immunologically relevant genes from the immature and the differently activated cells. Monocytes from three donors were used and treated separately as indicated in the summary. Equal amount total RNA from each donor was pooled prior to gene expression analysis.

Project description:To evaluate the DC genome-wide gene expression in response to beta-glucan and its regulation by IL-1 receptor antagonist (IL-1RA) we used a whole genome microarray. The gene expression profiling was performed in DC left untreated or exposed to beta-glucan for 4 and 12 h, in absence or presence of IL-1RA. This strategy allowed the identification of early/immediate and late/secondary genes regulated by beta-glucan in an IL-1-dependent and -independent manner. Human monocyte-derived DC were obtained by a 6/7-d cultures of freshly isolated monocytes with recombinant human IL-4 (10 ng/ml) and GM-CSF (50 ng/ml). Beta-glucan-associated gene expression and its regulation by IL-1RA in human DC was measured in cells left untreated or at 4 and 12 h after exposure to 10 ug/ml of particulate beta-glucan in absence or presence of 2.5 ug/ml of IL-1RA. Five different conditions (Untreated 0h, beta-glucan 4h, IL-1RA + beta-glucan 4h, beta-glucan 12h, and IL-1RA + beta-glucan 12h) were tested using DC from three different donors.

Project description:Macrophages are important effector cells of the immune system and play an important role in mounting inflammatory responses. Macrophages can be activated by different stimuli in the tissue, either by cytokines produced by T helper cells (M1 or M2 polarization) or by the pathogens they encounter. Macrophages are also important target cells of HIV-1 and are preferentially infected by CCR5-using viruses. In this study, we investigated the ability of HIV-1 to induce changes in gene expression in unpolarized macrophages as well as in M1 or M2 polarized cells. We observed that CCR5-using HIV-1 regulates the expression of genes that are also regulated by IL-4 in macrophages. Genes regulated by HIV-1 infection and IL-4 polarization are involved in dampening pro-inflammatory responses in macrophages, which may facilitate HIV-1 to escape from detection by other immune cells. We also observed that changes in macrophage gene expression triggered by CCR5-using HIV-1 differed from those regulated by a CXCR4-using virus. This indicates that CCR5-using HIV-1 may be able to modulate macrophage gene expression to achieve successful replication. Our results provide insight in the complex interplay between HIV-1 and cells of the immune system. Polarized macrophages were obtained by stimulation of primary human monocytes with IFN-gamma (250 U/ml) in combination with TNF-alpha (12.5 ng/ml) (M1), IL-4 (50 ng/ml) (M2a), IL-10 (50 ng/ml) (M2c) for 5 days. Cells were inoculated for 24 hours with one of two HIV-1 strains (CCR5 or CXCR4 using HIV1) or their non replicating counterparts (heat inactivated virus). Macrophages that were not stimulated wiht cyokines or inoculates with HIV-1 were used as control. A total of 16 treatment conditions were tested in triplicate, for a total of 48 samples analysed.

Project description:Interleukin-6 (IL-6) plays an important role in progressive bone loss in rheumatoid arthritis (RA). However, the molecular mechanisms through which IL-6 propels RA synovial fibroblasts (RASFs) to contribute to bone loss are not fully understood. In the present study, we investigated the effects of IL-6 and IL-6 receptor (IL-6/IL-6R induced trans-signaling in human RASFs. Treatment of human RASFs with IL-6 and IL-6 receptor (IL-6/IL-6R, 100 ng/ml each) alone or in combination with M-CSF (2 ng/ml) and RANKL (10 ng/ml) for 12 days resulted in the phenotypic changes to osteoclast-like features as determined by increase in TRAP staining and enhanced pit formation by ~3-fold in bone resorption assay in vitro. IL-6/IL-6R induced a dose-dependent increase in the expression of transcription factor Ets2 and enhanced its nuclear translocation in human RASFs. Interestingly, the untargeted proteomics analysis of the conditioned media from IL6/IL6R activated RASFs using Mass-Spectrometry (MS) technique and Trans-Proteomic Pipeline tool showed the production of 113 analytes unique to IL-6/IL-6R stimulation. Further analysis of the proteomics data using STRING database for pathway analysis showed the impact of IL-6/IL-6R on immunometabolic reprogramming of human RASFs towards osteoclast-like phenotype, which was partly mediated through Ets2. These preliminary studies identified a novel role of IL-6/IL-6R-mediated trans signaling in the metabolic reprogramming in RASFs that could potentially be targeted by inhibiting Ets2 to limit their role in bone resorption in RA.

Project description:ILC2 cells are a newly described cell type whose biology and contribution to disease are poorly understood. ILC2 cells are activated by allergens, viral infection, and/or epithelial damage via IL-33 and IL-25. ILC2 cells require IL-2, IL-7, IL-25 and IL-33 for their survival and expansion. In mice, ILC2s produce multiple mediators primarily associated with type 2 inflammation (IL-13, IL-5, IL-4, IL-6, IL-9, IL-10, GM-CSF, amphiregulin). ILC2 cells may contribute to the pathology of asthma through multiple mediators that include IL-13-independent pathways. Our goal is to compare transcriptional profiles of IL-33- or IL-25-activated ILC2 cells from blood to characterize these cells and to identify marker(s) that can be utilized to detect them in human tissue. ILC2 cells (Lineage negative, CRTH2+, CD161+, CD127+) were purified from human blood of 5 different donors by flow cytometry. The ILC2 yield ranged from 20,000 to 165,000 cells per donor (0.001-0.008% WBC). Purified ILC2s were expanded in vitro in the presence of IL-2, IL-7, IL-33 and IL-25 (each at 50 ng/ml) for 7-10 days. Expanded cells maintained the ILC2 phenotype (Lineage negative, CRTH2+, CD161+, CD127+). The cells were rested for 2 days in the presence of 1 ng/ml IL-2 and IL-7 and then treated in the presence of 1 ng/ml IL-2 and IL-7 with either media control, IL-25 (50 ng/ml), IL-33 (50 ng/ml), and/or TSLP (50 ng/ml) in combination, for 6 or 24 hours. Whole RNA was isolated via the RNeasy kit (Qiagen). Stratagene Universal Human Reference RNA was used as the reference.

Project description:Analysis of alternative activation of macrophages at gene expression level. The study forms part of a wider study where we compare the effects of IL-4 in different human and mouse macrophages. Our results support the notion that in vitro culture conditions greatly affect the macrophage response to IL-4. Total RNA obtained from human monocyte derived macrophages upon exposure to 10 ng/ml of IL-4 for 48 hours. Monocytes were induced to mature into macrophages using X Vivo 10 medium supplemented with 1% autologous serum.
