Project description:The aim was to investigate the total circular RNA profile in patients with relapsing–remitting multiple sclerosis and healthy control. We analyzed close to 14,000 individual circRNA per sample.

Project description:Relapsing Remitting Multiple Sclerosis Patients have an Altered Gut Mycobiome
Project description:We here analyzed CSF and blood from two relapsing-remitting multiple sclerosis (RRMS) patients early after peripheral leukocyte depletion with the anti-CD52 antibody alemtuzumab compared to untreated RRMS and control patients using single cell RNA-sequencing.
Project description:We analyzed the transcriptome profile of B cells from patients with relapsing-remitting multiple sclerosis (RRMS), patients with primary progressive multiple sclerosis (PPMS) and healthy individuals. High-density Clariom D Arrays for human were used to quantify the transcript levels. This GEO entry provides the processed Clariom D microarray data from the gene-level and exon-level workflows.
Project description:Multiple sclerosis (MS) is a chronic and progressive neurological disease. MS is characterized by early-stage neuroinflammation, neurodegeneration, and demyelination, with a spectrum of heterogeneous clinical manifestations in terms of disease course and response to therapy. The currently unsatisfied availability of diagnostic and prognostic biomarkers concerning disease progression and treatment response represents an important requirement for therapy individualization and drug efficacy. Specific Disease Therapies (DMTs) are available to prevent MS-related brain damage; however, the specific drug choice is still under debate and needs further characterization. Since differentially expressed miRNAs have been proposed as diagnostic tools in neurodegenerative/neuro-inflammatory diseases, such as multiple sclerosis, amyotrophic lateral sclerosis, and Alzheimer's disease, we characterized the miRNA expression profiling in peripheral blood mononuclear cells (PBMC) of subjects with relapsing-remitting MS treated with high efficacy DMTs: Cladribine (CLA, n=11 patients) or Ocrelizumab (OCRE, n=14 patients). The treated patients were compared to control (CTR) untreated subjects (n=15). Blood samples were collected from patients before treatment (time t0) and 6 months post-treatment (time t1), but just once from control subjects. CLA drug tablets were administered to the selected relapsing-remitting MS patients with a dosage of 1.75 mg/kg given for 5 days. OCRE drug was administered to the other relapsing-remitting MS patients by infusion with a dosage of 300 mg, twice in two weeks.
Project description:Interferon (IFN) beta-1a is an approved treatment for relapsing remitting multiple sclerosis (RRMS) and has been examined for use in secondary progressive multiple sclerosis (SPMS). However, no information regarding blood transcriptional changes induced by IFN treatment in SPMS patients is available. Our aim was to identify a subgroup of SPMS patients presenting a gene expression signature similar to that of RRMS patients who are clinical responders to IFN treatment.
Project description:Blood-brain-barrier (BBB) breakdown and active inflammation by relapsing–remitting (RRMS) lesions are hallmarks of multiple sclerosis (MS). Leaky endothelial junctions causes an increased expression of circulating immune cells with associated adhesion molecules on endothelial cell membrane but also an increased production of endothelial derived extracellular microvesicles (EV). Methods: Relapsing–remitting MS (RRMS) patients with no disease-modifying treatment were monitored with weekly intervals using high-resolution 3T MRI scanning. Plasma samples from each measurement were analyzed for protein biomarkers of inflammation by quantitative proteomics, cytokines and chemokines using multiplex immunoassay. Extracellular microvesicles were characterized by an optimized endothelial stress EV Array analysis for detection of soluble secreted microvesicles.
Project description:Multiple sclerosis biomarker discovery in pooled cerebrospinal fluid (CSF) using glycopeptide enrichment, TMT labeling and LC-MS/MS. Comparing 3 pools of CSF from relapsing-remitting MS (RRMS) patients to 3 pools of CSF from patients with other neurological diseases (OND). To reveal protein groups and networks affected by MS and to look at correlation between a glyco and a global approach.
