PBMC gene expression of early onset of the first demyelinating event of acute optic neuritis

ABSTRACT: Optic neuritis (ON) is a common manifestation of multiple sclerosis (MS); it appears as the presenting symptom in about 25% of MS patients and occurs in 30–70% of patients with MS during the course of their illness Purpose. To evaluate the molecular pathways that operate in the early phase of acute ON by studying gene expression profiles of peripheral blood mononuclear cells (PBMCs) subpopulations including CD19+ B cells, CD14+ macrophages, CD4+ and CD8+ T cells. High throughput gene expression analysis was performed on periferal mononuclear blood cells (PBMC) samples from 6 patients within 96 hours of the acute onset of the first demyelinating event of optic neuritis and 9 age matched healthy subjects using Affymetrix Inc. technology

Expression data from peripheral blood mononuclear cells in multiple sclerosis patients and controls

Project description:Multiple sclerosis (MS) is a neurodegenerative disease with a presumed autoimmune component. Expression profiling in immune cells can therefore be used in order to identify genes and pathways involved in MS pathogenesis. We conducted a genome-wide expression study in peripheral blood mononuclear cells (PBMC) from 12 MS patients and 15 controls in order to identify differentially expressed genes and pathways in MS. PBMCs were isolated from whole blood and total RNA was extracted.

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).

Transcriptional changes in demyelinating canine distemper virus encephalitis

Project description:Canine distemper virus (CDV)-induced demyelinating leukoencephalitis (CDV-DL) in dogs is a translational animal model for human demyelinating diseases such as multiple sclerosis. The aim of this study was to perform an assumption-free microarray analysis of gene expression in different subgroups of CDV-DL as compared to normal controls. Dogs were classified into normal controls (group 1), acute CDV-DL lesions with CDV within the brain but without demyelination and inflammation (group 2), subacute lesions with demyelination but without inflammation (group 3), and subacute to chronic lesions with demyelination and inflammation (group 4).

Co-Morbid Multiple Sclerosis and Psoriasis: Clinical Outcomes and Gene Expression

Project description:Psoriasis was found to ameliorate multiple sclerosis (MS) outcomes when it MS onset. However, the molecular basis for this observation remains unclear. Herein, we compared the blood mononuclear cell transcriptome of psoriasis and MS comorbide (P/MS) patients with that of patients with either psoriasis or MS to understand the clinical observation.

Astrocyte-Derived Clusterin Disrupts Glial Physiology to Obstruct Remyelination in Mouse Models of Demyelinating Diseases

Project description:Multiple sclerosis (MS) is a debilitating demyelinating disease characterized by remyelination failure attributed to inadequate oligodendrocyte precursor cells (OPCs) differentiation and aberrant astrogliosis. A comprehensive cell atlas reanalysis of clinical specimens brings to light heightened clusterin (CLU) expression in a specific astrocyte subtype links to active lesions in MS patients. Our investigation reveals elevated astrocytic CLU levels in both active lesions of patient tissues and female murine MS models. CLU administration stimulates primary astrocyte proliferation while concurrently impedes astrocyte-mediated clearance of myelin debris. Intriguingly, CLU overload directly impedes OPCs differentiation and induces OPCs and OLs apoptosis. Mechanistically, CLU suppresses PI3K-AKT signaling in primary OPCs via very low-density lipoprotein receptor. Pharmacological activation of AKT rescues the damage inflicted by excess CLU on OPCs and ameliorates demyelination in the corpus callosum. Furthermore, conditional knockout of CLU emerges as a promising intervention, showcasing improved remyelination processes and reduced severity in murine MS models.

Gene-expression in peripheral blood mononuclear cells from untreated MS patients

Project description:The aim of this study was to identify differentially expressed genes in peripheral blood mononuclear cells from MS patients that were responders or non-responders to the neuroantigen myelin basic protein. Using microarray we measured mRNA-expression levels in freshly isolated peripheral blood mononuclear cells from 17 untreated patients with multiple sclerosis. Based on studies, measuring the responses of blood derived T-cells to myelin basic protein ex vivo, these 17 untreated MS-patients can be divided into two groups: 4 of the untreated multiple sclerosis patients had T-cells that responded to myelin basic protein ex vivo whereas 13 untreated MS patients had T-cells that did not respond to myelin basic protein ex vivo.
