Gene expression profiling of mouse experimental autoimmune encephalomyelitis (EAE) from spinal cord preparations of opticospinal EAE (OSE) and MOG-induced EAE

Project description:Genetic opticospinal EAE (OSE) and MOG-induced EAE (MOG-EAE) are two experimental autoimmune encephalomyelitis (EAE) mouse models of human multiple sclerosis. For the OSE model, double-transgenic 2D2 (TCRMOG) x IgHMOG mice were used. For MOG-EAE, wildtype C57BL/6 mice were immunized with a MOG peptide consisting of the amino acids 35-55, administered in complete Freund’s adjuvant containing 5mg / ml Mycobacterium tuberculosi. The severity of EAE was rated on the scale 0: healthy animal; 1: animal with a flaccid tail; [...]; 4: animal with both hind legs paralyzed. The case groups in the experiment were: OSE1: OSE with disease score 1; OSE4: OSE with disease score 4; MOG4: MOG-EAE injected with both MOG and adjuvant, with disease score 4. The control groups in the experiment were: OSE0: OSE with disease score 0; CFA: C57BL/6 mice injected only with adjuvant (no MOG); WT: Wildtype C57BL/6 mice. The aim of the experiment was to assess gene expression differences 1) between OSE4 and OSE0, 2) between OSE1 and OSE0, and 3) between MOG4 and CFA. For control, WT was compared to OSE0 and CFA. Subsequently, differentially expressed transcripts were compared, first, between the OSE4 vs. OSE0 and the MOG4 vs. CFA contrasts (different EAE models) and, second, between the OSE4 vs. OSE0 and the OSE1 vs. OSE0 contrasts (different EAE severity).

Mouse brain proteome map of Experimental autoimmune encephalomyelitis (EAE) mouse model

Project description:Multiple sclerosis (MS) is an autoimmune disease of the central nervous system (CNS); its cause is unknown. To understand the pathogenesis of MS, researchers often use the experimental autoimmune encephalomyelitis (EAE) mouse model. Here, our aim was to build a proteome map of the biological changes that occur during MS at the major onset sites—the brain and the spinal cord. We performed quantitative proteome profiling in five specific brain regions and the spinal cord of EAE and healthy mice with high-resolution mass spectrometry based on tandem mass tags.

miRNAs expression in spinal cords of experimental autoimmune encephalomyelitis (EAE) mice

Project description:MicroRNAs (miRNAs) have been implicated as fine-tuning regulators controlling diverse biological processes at the level of posttranscriptional repression. Dysregulation of miRNAs has been described in various disease states, including inflammatory autoimmune diseases. By using high-throughput microRNA profiling analysis, we identified a series of miRNAs dysregulated in local inflammatory lesions of human patients with autoimmune diseases, as well as their relevant mouse models such as EAE. We isolated the spinal cords pooled from six EAE mice or from six naM-CM-/ve control mice. Total RNA was extracted for the TaqManM-BM-. Low Density Assay v3.0

Analysis of a non-obese diabetes-experimental autoimmune encephalomyelitis (NOD-EAE)

Project description:The purpose of this study was to analyze and elucidate the mechanisms of non-obese diabetes-experimental autoimmune encephalomyelitis (NOD-EAE), an animal model of progressive multiple sclerosis (MS), and to compare the pathological features with those observed in human progressive MS. To achieve this, pathological analysis, flow cytometry analysis, immunohistochemical staining, and transcriptome analysis were performed at each pathological stage of the NOD-EAE mice to characterize each pathological stages in the lesion. In the chronic phase of the NOD-EAE mice, fibrosis and lymph follicle formation, characteristic of progressive human MS, were observed. We describe the pathological profile and transcriptome analysis of the NOD-EAE mice and verify that this model has similar features to those of human progressive MS. Our findings suggest that this model recapitulates lymph follicle formation, a disease hallmark of progressive MS, and fibrosis, a feature complicating the pathogenesis of MS in the chronic phase.

Effects of FTY720 on B cells in experimental autoimmune encephalomyelitis (EAE)

Project description:MP4-induced experimental autoimmune encephalomyelitis (EAE) is a B cell-dependent mouse model of multiple sclerosis (MS), which enables targeted research on B cells, currently much discussed protagonists in MS pathogenesis. Here, we used this model to study the impact of the S1P1 receptor modulator FTY720 (fingolimod) on the autoreactive B cell and antibody response both in the periphery and central nervous system (CNS) itself.

Transcriptomic profiling of choroid plexus in experimental autoimmune encephalomyelitis

Project description:Multiple sclerosis (MS) is a demyelinating disease causing major neurological disability in young adults. We characterized the transcriptome of the choroid plexus (CP), which is part of the blood-brain barriers and the major site of cerebrospinal fluid (CSF) production, in the experimental autoimmune encephalomyelitis mouse model of MS. Genes encoding for adhesion molecules, chemokines and cytokines displayed the most altered expression, supporting the CP as a site of immune-brain interaction in MS. The gene encoding for lipocalin 2 (LCN2) was the most up-regulated, and CSF LCN2 levels coincided with the phases of active disease. Total RNA was isolated with Trizol (Invitrogen, Carlsbad, CA, USA) following the manufacturer’s instructions. After quality assessment using the Agilent Bioanalyzer (Agilent Technologies, CA, USA), 100ng of total RNA from 3 pooled controls and 3 or 2 pooled samples of each experimental autoimmune encephalomyelitis (EAE) phase were amplified and labelled with the Illumina TotalPrep RNA Amplification Kit (Illumina Inc., San Diego, CA, USA). The labeled cRNA was then hybridized using the recommended protocol in a total of two Illumina Whole-Genome MouseRef-8 expression Beadchips (Illumina Inc., San Diego, CA, USA).

Transcriptome profiling of a backcross between experimental autoimmune encephalomyelitis (EAE)-susceptible DA and EAE-resistant PVG rat strains to identify expression quantitative trait loci.

Project description:The aim of the experiment is to characterize the genetics and mechanisms of the inflammatory response after induction of experimental autoimmune encephalomyelitis (EAE), a model of multiple sclerosis, by studying the genome wide expression in the spleen in late disease. A backcross was created between EAE-susceptible DA and EAE-resistant PVG rats. At day 35 after induction of EAE with myelin oligodendrocyte glycoprotein (MOG) in these rats, spleens were taken for transcriptional profiling.

Gene Expression Changes in the Spinal Cords of Lewis Rats with Myelin Basic Protein-Induced Experimental Autoimmune Encephalomyelitis (EAE)

Project description:Myelin Basic Protein (MBP) induced experimental autoimmune encephalomyelitis (EAE) in the Lewis rat, produces an an acute weakness, or paralysis of the tail and hind limb ataxia ,weakness or paralysis associated with increased permiability of the blood brain barrier, inflammation and demyelination in central nervous system (CNS). Clinical symptoms , ascending weakness or paralysis of the tail followed by the hind limbs and in rare cases the fore limbs occurs 8 and 14 days post immunisation (dpi) and is generally resolved completely by day 20 dpi. We have carried out transcriptome analysis of total RNA from the spinal cords of female Lewis rats at the peak of disease (EAE) and age matched healthy controls to identify gene expression changes associated with the disease. In these data sets we include the exon and gene expression data obtained from total RNA preparations from the spinal cords of female Lewis rats sacrificed at the clinical peak of MBP induced EAE and age matched , untreated, healthy controls. This data was used to obtain 2265 mapped IDS wich identified 1190 known genes which were differentially expressed in the spinal cord in EAE compared to healthy animals. 8 total RNA samples were prepared. A two way ANOVA comparison carried out in Partek Genomics Suite was used to detect gene transcripts for which the expression levels varied significantly (un-adjusted p-values M-bM-^IM-$ 0.05) from the healthy controls. 2265 mapped IDs were uploaded to the Ingenuity pathway analysis suite (IPA) where 1190 known genes were identified as being differentially regulated between groups. An FDR M-bM-^IM-$ 5% and fold change limit of +/- 4.0 further refined the data set to identify the 72 most highly and significantly differentially regulated genes in the spinal cord at the clinical peak of disease in MBP induced EAE in the Lewis rat.
