Project description:IFNb has been used as a first line therapy for relapsing remitting multiple sclerosis (RRMS). Since only a few studies have addressed the role of endogenous IFNb in the pathogenesis of the disease, our objective was to characterize its role in the transcriptional regulation of pathogenic Th17 cytokines in patients with RRMS. In-vitro studies have demonstrated that IFNb inhibited IL-17A, IL-17F, IL-21, IL-22 and IFN-b secretion in CD4+ lymphocytes through the induction of suppressor of cytokine secretion (SOCS)1 and 3. We found that patients with RRMS have increased serum and cerebrospinal fluid (CSF) Th17 (IL-17A and IL-17F) cytokine levels in comparison to the control subjects, suggesting that deficient endogenous IFNbeta secretion and/or signaling may contribute to the dysregulation of those pathogenic cytokines in CD4+ cells. We identified that the endogenous IFNb from serum of RRMS patients induced a significantly lower IFN-inducible gene expression in comparison to healthy controls (HCs). In addition, in-vitro studies have revealed a deficient endogenous and exogenous IFNb signaling in CD4+ cells derived from MS patients. Interestingly, upon inhibition of the endogenous IFNb signaling by silencing interferon regulatory factor (IRF)7 gene expression, the resting CD4+ T cells secreted significantly higher level of IL-17A, IL-17F, IL-21, IL-22 and IL-9, suggesting that endogenous IFNb suppresses the secretion of these pathogenic cytokines. In-vivo recombinant IFNb-1a treatment induced IFNAR1 and its downstream signaling moleculesM-bM-^@M-^Y gene expression, suggesting that treatment may reconstitute a deficient endogenous IFNbeta regulation of the CD4+ T-cellsM-bM-^@M-^Y pathogenic cytokine production in MS patients. Gene expression changes induced by IFNM-NM-2M-bM-^HM-^R1a were tested using Affymetrix Human Genome U133 (HG-U133) arrays (Affymetrix) that contain 45,000 probe sets representing 39,000 transcripts derived from approximately 33,000 human genes. 107 PBMCs per condition derived from 15 CIS patients were stimulated with plate-immobilized M-NM-1CD3 (1 M-NM-<g/ml) and M-NM-1CD28 (5 M-NM-<g/ml) mAb (BD Biosciences) in the absence or presence of IFNM-NM-2-1a (1000 U/ml) (EMD Serono Inc) for 24 h in serum-free medium (Gibco). Cells were harvested and the total RNA was isolated using a Rneasy kit (Quiagen). Arrays were hybridized for 16 hours at 45oC in the GeneChipM-BM-. Hybridization Oven 640 (Affymetrix). The arrays were washed and stained with R-phycoerythrin streptavidin in the GeneChipM-BM-. Fluidics Station 400 (Affymetrix). The arrays were scanned with a Hewlett Packard GeneArray Scanner. Affymetrix GeneChipM-BM-. Microarray Suite 5.0 software was used for washing, scanning and basic analysis.

Project description:The innate immune response - the expression programme that is initiated once a pathogen is sensed - is known to be variable among responding cells, as well as to rapidly evolve in the course of mammal evolution. To study the transcriptional divergence and cell-to-cell variability of this response, we stimulated dermal fibroblast cells from two primates (human and macaque) and two rodents (mouse and rat) with dsRNA - a mimic of viral RNA that elicits a rapid innate immune response. Subsequently, we profiled the response using bulk RNA-seq, scRNA-seq and ChIP-seq across the four species and across different time points.<br>This experiment contains data of dermal fibroblasts from 3 human individuals, unstimulated, sequenced by 10X Genomics technology.

Project description:This experiment set is used for the manuscript entitled: Pharmacogenomics of Interferon-b therapy in multiple sclerosis: Baseline IFN signature determines pharmacological differences between patients. In this study we generated and analyzed pre- and post- IFNb treatment gene expression patterns of RRMS patients with the aim of identifying pre-existing and/or drug-induced signatures that will allow us to make predictions on the expected pharmacological effects of IFNb treatment. We show that the expression level of IFN response genes prior to treatment, determines the pharmacological differences between patients with MS at the molecular level. A group of 16 Dutch patients (10 females and 6 males) with clinically definite relapsing-remitting MS was recruited from the outpatient clinic of the MS Centre Amsterdam. Mean age at start of IFNb therapy is 40.6 +/- 7.7, mean EDSS is 2.3 +/- 1.3 (range 1-6). Blood samples were obtained just before treatment and 1 month after start of the therapy. Patients received Avonex, Betaferon, Rebif 22 or Rebif 44. A compound treatment design type is where the response to administration of a compound or chemical (including biological compounds such as hormones) is assayed.

Project description:To determine the impact of MEM40 and IFNB on normal human donor monocyte-derived DCs (Mo-DCs) phenotype, we used an experimental design where human A549 lung cancer cells were first infected with Ad-Null or adenoviruses expressing human IFNB, MEM40 or MEM40 + IFNB, followed by removal of virus-containing supernatant and co-culture with Mo-DCs. We used the above design followed by sorting of MHC-II+ CD11c+ cells for bulk RNA-sequencing.

Project description:Interferon-b (IFN-b) belongs to the type I interferon family of cytokines and via binding to its receptor, interferon-a/b-receptor (IFNAR), it exerts immunoregulatory effects such as anti-viral and anti-inflammatory properties, and clinical benefits for patients with the CNS disease multiple sclerosis. To compare differentially regulated genes in neurons of interferon-beta knock out mice (Ifnb–/–), we conducted a microarray analysis on cerebellar granular neurons (CGNs) from wt (Ifnb+/+) and Ifnb-/- mice with or without treatment with recombinant IFN-b.
