We report the results of a meta-analysis of genome-wide association scans for multiple sclerosis (MS) susceptibility that includes 2,624 subjects with MS and 7,220 control subjects. Replication in an independent set of 2,215 subjects with MS and 2,116 control subjects validates new MS susceptibility loci at TNFRSF1A (combined P = 1.59 x 10(-11)), IRF8 (P = 3.73 x 10(-9)) and CD6 (P = 3.79 x 10(-9)). TNFRSF1A harbors two independent susceptibility alleles: rs1800693 is a common variant with modes ...[more]

Expression profiles of PBMC from multiple sclerosis patients

Project description:Affymetrix GeneChip Human Gene 1.0 ST Array was applied to compare the expression profiles in peripheral blood mononuclear cells(PBMC) between healthy controls and multiple sclerosis patients(MS pt). It suggested that certain genes involved in apoptosis pathway have been changed regulated in PBMC from MS pt. Applying Affymetrix GeneChip Human Gene 1.0 ST Array and the mixed effects model for gene set analysis, we compared gene expression profiles between 8 multiple sclerosis (MS) patients and 4 healthy controls (HC).

Concurrent gliomas in patients with multiple sclerosis

Project description:Background: Concurrent malignant brain tumors in patients with multiple sclerosis (MS) constitute a rare but paradigmatic phenomenon for studying neuroimmunological mechanisms from both molecular and clinical perspectives. Methods: A multicenter cohort of 26 patients diagnosed with both primary brain tumors and multiple sclerosis was studied for disease localization, tumor treatment-related MS activity, and molecular characteristics specific for diffuse glioma in MS patients. Results: MS neither predisposes nor protects from the development of gliomas. Patients with glioblastoma WHO grade 4 without isocitratdehydrogenase (IDH) mutations have a longstanding history of MS, whereas patients diagnosed with IDH-mutant astrocytoma WHO grade 2 receive multiple sclerosis diagnosis mostly at the same time or later. Concurrent MS is associated with a lesser extent of tumor resection and a worse prognosis in IDH-mutant glioma patients (PFS 32 vs. 64 months, p=0.0206). When assessing tumor-intrinsic differences no distinct subgroup-defining methylation pattern is identified in gliomas of MS patients compared to other glioma samples. However, differential methylation of immune-related genetic loci including human leukocyte antigen locus on 6p21 and interleukin locus on 5q31 is found in MS patients vs. matched non-MS patients. In line, inflammatory disease activity increases in 42% of multiple sclerosis patients after brain tumor radiotherapy suggesting a susceptibility of multiple sclerosis brain tissue to pro-inflammatory stimuli such as ionizing radiation. Conclusions: Concurrent low-grade gliomas should be considered in multiple sclerosis patients with slowly progressive, expansive T2/FLAIR lesions. Our findings of typically reduced extent of resection in MS patients and increased MS activity after radiation may inform future treatment decisions.

Gene expression profile in CD4+ and CD8+ T cells from identical twins discordant for Multiple sclerosis

Project description:To gain insight into the etiopathogenesis of Multiple sclerosis (MS) we investigated gene expression changes in CD4+ and CD8+ T lymphocytes from monozygotic twins (MZ) discordant for relapsing remitting MS. We studied 4 monozygotic twin pairs discordant for disease, with the affected co-twin free of disease modifying therapies (F/M = 3/1, mean age 36.25±3.9). Following leukapheresis, CD4+ and CD8+ T cells were separated and studied by Affymetrix GeneChip®

Physical activity diminish fatigue and systemic interferon response in multiple sclerosis

Project description:Objective: To evaluate gene expression profiles in multiple sclerosis (MS) patients who improved their fatigue status after a program of physical exercise and to compare them with healthy controls (HC). Methods: A prospective longitudinal study was conducted. Gene expression in whole blood was profiled at baseline in 7 healthy controls and also in 7 fatigued-MS patients. Patients underwent a physical exercise program for 6 months, and their fatigue status and gene expression profiles were again analyzed at the end of this program. Results: MS patients showed a significant activation of genes participating in the systemic interferon response in comparison with healthy controls. Fatigue improved at the end of the physical activity program, and, in parallel, systemic activation of interferon related genes disappeared. Conclusions: Fatigue improvement following an exercise program is associated to down modulation of interferon activity at the systemic level in MS patients. Our results provide a biological basis for the observed benefit of physical exercise in MS.

Expression data of multiple sclerosis patients receiving Interferon-beta therapy [miRNA-2_0]

Project description:The purpose of this study was to investigate the expression dynamics of mRNAs and microRNAs in response to subcutaneous IFN-beta-1b treatment (Betaferon, 250 Âµg every other day) in patients with clinically isolated syndrome (CIS) suggestive of multiple sclerosis (MS) or relapsing-remitting type of the disease (RRMS). By using Affymetrix microarrays, we obtained microRNA expression profiles of peripheral blood mononuclear cells from 3 MS patients within the first month of IFN-beta treatment. EDTA blood samples were taken from all patients immediately before first IFN-beta injection as well as after 1 month. Total RNA of Ficoll-isolated peripheral blood mononuclear cells from each sample was extracted, labeled and hybridized to Affymetrix GeneChip miRNA 2.0 arrays to quantify the expression of small non-coding RNA transcripts. This GEO entry provides the GeneChip miRNA 2.0 microarray data.
