(Submitter supplied) Multiple sclerosis is the most common autoimmune disease of the central nervous system. Studying whole blood RNA from a cohort of 195 MS patients and 66 healthy controls, we identified gene expression signatures for interferon treatment and disease status by microarray analysis. Blood was collected at multiple time points (up to 3 for patients, 2 for controls). Patients were either untreated or treated with Interferon. more...

(Submitter supplied) One of our new major finding among the genes that contributes to MS susceptibility is ICSBP1. The so called disease modifying therapies like interferon-beta (IFN-β), possibly acting on the peripheral T-cells, reduce the disease activity and the clinical progression, with a MRI-detectable effect in preventing lesion burden and cerebral atrophy development in RR-MS. It suggests a critical role of peripheral blood mononuclear cells (PBMCs) immune response and modulation in developing inflammation in the brain. more...

(Submitter supplied) Background: In multiple sclerosis (MS), immune up-regulation is coupled to subnormal immune response to interferon-β (IFN-β) and low serum IFN-β levels. The relationship between the defect in IFN signalling and acute and long-term effects of IFN-β on gene expression in MS is inadequately understood. Methods: We profiled IFN-β-induced transcriptome shifts, using high-resolution microarrays on 227 mononuclear cell samples from IFN-β-treated MS Complete Responders (CR) stable for five years, and stable and active Partial Responders (PR), stable and active untreated MS, and healthy controls. more...

(Submitter supplied) This experiment was carried out in the context of a pharmacogenetic study of long-term (4-year follow-up) response to Interferon-beta treatment in two cohorts of Italian Multiple Sclerosis patients, to identify genetic variants (SNPs) that may influence response to IFN-beta. We integrated results from meta-analysis of the two cohorts with gene expression profiling of IFNβ stimulated PBMCs from 20 healthy controls and eQTL analyses, to look at possible enrichment of IFN-beta induced genes with genes mapped by top-ranking meta-analyzed SNPs.

(Submitter supplied) The purpose of this study was to characterize the transcriptional effects induced by subcutaneous IFN-beta-1a treatment (Rebif, 22 µg or 44 µg three times a week) in patients with relapsing-remitting form of multiple sclerosis (MS). By using Affymetrix DNA microarrays, we obtained genome-wide expression profiles of peripheral blood mononuclear cells from 12 MS patients within the first two years of IFN-beta administration.

(Submitter supplied) We measured mRNA expression for all known genes in whole blood from 144 individuals, 99 with MS (43 PPMS, 36 RRMS and 20 SPMS). Analysis of gene expression and genotype in these individuals has indicated the dominant genetic association with T cell regulation is matched by the dominant pattern of dysregulation of T cell gene expression in MS and its clinical subtypes.

(Submitter supplied) Rheumatoid arthritis (RA) is a systemic autoimmune disease and its underlying molecular mechanisms are still poorly understood. Previously a CD4 T-cell microarray study has only focused arthritis patients. We aimed to compare the molecular profiles of active RA versus healthy control in CD4 T cells. We used microarrays to detail the global programme of gene expression in active RA and healthy control.

(Submitter supplied) Myelin-reactive T cells have been identified in patients with multiple sclerosis (MS) and healthy subjects with comparable frequencies, but the contribution of these autoreactive T cells to disease pathology remains unknown. A total of 13,324 T cell libraries generated from blood of 23 patients and 22 healthy controls were interrogated for reactivity to myelin antigens. Libraries derived from CCR6+ myelin-reactive T cells from patients with MS exhibited significantly enhanced production of IFN-γ, IL-17, and GM-CSF compared to healthy controls. more...

(Submitter supplied) Background and aim: The disease course and clinical phenotype in multiple sclerosis (MS) are highly variable and therefore, biomarkers are needed. Studies have shown a dysregulation in the coding and non-coding RNAs and proposed some as biomarkers. However, still none of them have reached the clinical practice. Recently, circular RNAs (circRNAs) have emerged as new players in the transcriptome that hold a great potential as biomarkers in several diseases. more...

(Submitter supplied) Efforts to improve resilience in livestock production systems have focused on two objectives: investigating the genetic control of immune function as it pertains to robustness and disease resistance, and finding predictive markers for use in breeding programs. In this context, the peripheral blood transcriptome represents an important source of biological information about an individual's health and immunological status, and has been proposed for use as an intermediate phenotype to measure immune capacity. more...
