Project description:NK cells are believed to contribute to the control of hepatitis C virus infection and pathogenesis of liver disease. Standard treatment of both acute and chronic hepatitis C is based on the administration of interferon alpha, however, the effects of type I interferons on human NK cells have not been studied in the context of hepatitis C. We therefore first performed a microarray screen for genes differentially regulated in human NK cells after stimulation of PBMC with recombinant interferon alpha-2b. One of the genes upregulated was TRAIL which was confirmed in vitro on the protein level. Keywords: Interferon alpha; human NK cells; stimulation for 6 hours; cells sorted after stimulation of whole PBMC NK cells of PBMC of five healthy controls have been either isolated directly or after culturing for 6h in media containing 10% human AB serum supplemented with 1 and 100 ng/ml recombinant IFNa-2b. RNA of NK cells of the healthy controls was isolated and RNA was pooled for the hybridization.

Project description:This experiment aims to identify the biological pathways and diseases associated with the cytokine Interleukin 13 (IL-13) using gene expression measured in peripheral blood mononuclear cells (PBMCs). The experiment comprised of samples obtained from 3 healthy donors. The expression profiles of in vitro IL-13 stimulation were generated using RNA-seq technology for 3 PBMC samples at 24 hours. The transcriptional profiles of PBMCs without IL-13 stimulation were also generated to be used as controls. An IL-13R-alpha antagonist (Redpath et al. Biochemical Journal, 2013) was introduced into IL-13 stimulated PBMCs and the gene expression levels after 24h were profiled to examine the neutralization of IL-13 signaling by the antagonist.

Project description:Stimulation experiments were done with PBMC from SLE or healthy donors treated with CSL362 or isotype control before stimulation with various stimuli including the TLR9 agonist 0.25 μM CpGc; the TLR4 agonist 10 μg/ml LPS; and the TLR3 agonist 10 μg/ml POLY I:C. As well as the SLE specific stimuli SLE immunoglobulin (Ig) + necrotic cell lysates (NCL) to form immune complexes; control healthy donor Ig + NCL; and SLE sera + NCL; or healthy donor sera + NCL to understand the specific effects of pDC depletion on different inducible gene transcripts.

Project description:We report cytokine specific changes in gene expression in the human neutrophil transcriptome using TNF-alpha and GM-CSF stimulation of healthy neutrophils Healthy human neutrophils were stimulated with TNF-alpha or GM-CSF for 1h in vitro. RNA was analysed by SOLiD and Illumina sequencing. RNA from one biological donor was sequenced on both platforms, and two different biological donors were sequenced by Illumina.

Project description:We performed RNA-seq on peripheral blood mononuclear cells (PBMC) from healthy human donors treated with interferon alpha 2a (1000IU/mL) +/- dexamethasone 10^-7M, with the aims of studying interactions between IFN and glucocorticoid induced gene expression, as well as identifying potential transcripts that may be used as a glucocorticoid exposure signature in clinical practice in patients with SLE. Transcripts identified from RNA-seq data were analysed in SLE patient data sets to validate clinical utility. We found that dexamethasone minimally impacts on interferon stimulated gene expression however IFN altered gene transcription of many previously reported glucocorticoid induced genes.

Project description:Samples in this study probe the gene expression kinetics in human CCR6+ Th17 memory T cells activated under Th17 condition. Human CCR6+ Th17 memory T cells were purified from PBMC and gene expression was studied over a time course of 3 days after activation under Th17 condition. RNA from these samples was also profiled using RNA-Seq to compare different transcriptome profiling technologies. PBMCs were purified from whole blood from a healthy donor. CD4+ cells were isolated by negative selection, followed by CCR6+ purification by positive selection. Two replicates of 6 time points were taken following stimulation in Th17 polarizing conditions. This submission represents microarray component of study.

Project description:CD8+ cytotoxic T lymphocytes (CTLs) play a major role in defense against intracellular pathogens, and their functions are specified by antigen recognition and innate cytokines. While effector CTLs eliminate the infection, a small population of memory cells are retained that yields more rapid and robust response upon re-infection. Antigen presenting cells secrete an array of innate cytokines including IL-12 and IFN-α after recognition of pathogens. Both IL-12 and IFN-α have been shown to act as the third signal regulating the development of CTLs. We have shown that these two cytokines have a non-redundant effect in generation of human effector CTL. IL-12 alone is sufficient for effector CTL genesis marked by IFN-γ and TNF-α production, as well as increased cytolytic activity. Even in the presence of IFN-α, IL-12 programs CTLs that express the chemokine receptor CXCR3 and effector cytokines. Using microarray analysis we have investigated how IL-12 and IFN-α differentially regulate the genetic programming pathways that give rise to effector CTLs among multiple human donors. We have also analyzed the gene expression patterns of cells sorted from healthy human peripheral blood that display surface markers of effector memory CTL (designated as ex vivo) samples. 5 healthy human donor samples were used for the in vitro cultures. For each donor the CFSE labeled cells (CD8+CD45RA+) were cultured in the presence of neutralized, IL-12, IFN-a, and IL-12+IFN-a conditions and plate-bound anti-CD3+anti-CD28 for 3.5 days. Total RNA from CFSEhi (Undiv) and CFSElo (Div) sorted cells were used for Illumina Bead Array. 4 healthy human donor samples were used for the ex vivo samples. Total RNA was collected from FACS sorted CD8+CCR7hiCXCR3lo and CD8+CCR7loCXCR3hi cells without any stimulation.
