Project description:Experimental autoimmune encephalomyelitis (EAE) is a mouse model for multiple sclerosis (MS) a chronic autoimmune disease of the central nervous system. We have observed dysfunction of the RNA binding protein hnRNP A1 in neurons from the brains of patients with MS, and the spinal cords of mice with EAE. Here, we sought to characterize the consequences of EAE-induced dysfunction of hnRNP A1 on the RNAs it binds by using CLIPseq to establish both the normal central nervous system RNA binding profile of hnRNP A1 in the spinal cords of naive mice, and any alterations to the binding profile of hnRNP A1 in the spinal cords of mice with EAE.
Project description:We compared RNA samples extracted from spinal cords of control (C) and AT-EAE (E) mice using the "Multiple Yellow" strategy. 4 distinct C-extracts were hybridized with two slides and 4 distinct E-extracts with other two slides, and the green/red normalized signals were compared separately and the E/C ratios averaged.

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.
Project description:Disruption of blood-brain barrier (BBB) integrity is a hallmark of several neurological disorders. Here we show that the BBB is dynamically and differentially affected during the preclinical, progression and remission phase of experimental autoimmune encephalomyelitis (EAE), an animal model of multiple sclerosis (MS). We isolated vascular fragments, representing the BBB, from spinal cords of imatinib and PBS treated mice at the preclinical, progression and remission phase of MOG-EAE as well as from non-immunized, naive mice.

Project description:To evaluate DR?1-mMOG-35-55 effects on CNS inflammation during Experimental allergic encephalomyelitis (EAE) in a more comprehensive manner, we performed microarray analysis on spinal cords from DR?1-mMOG-35-55- vs. Vehicle-treated DR*1501-Tg mice with EAE. EAE was induced with mMOG-35-55/CFA/Ptx and mice were treated with DR?1-mMOG-35-55 (100ug daily x 3) or Vehicle ,after disease onset at a clinical score of 2. Twenty four hr after the last treatment, total RNA was isolated from spinal cords and gene expression profiles from pooled RNA were analyzed using the Mouse Gene 2.0 ST Affymetrix GeneChip system RNA was isolated from spinal cords of 3 DRa1-mMOG-35-55 treated mice and 3 Vehicle treated mice,and pooled in to two groups SCV - for Vheicle treatment and SCA - for DRa1-mMOG-35-55 treatment
Project description:We have performed transcriptomic analysis in the spinal cord of experimental autoimmune encephalomyelitis (EAE) mice compared to naive mice at different time intervals in order to observe the gene expression changes within the CNS compartment
Project description:B10.PL mice with severe (stage 2.5-3) experimental autoimmune encephalomyelitis were treated with placebo or 200 ng 1,25(OH)2D3. Six hours later, the spinal cords were harvested and mRNA was extracted for microarray analysis. Naive mice serve as controls. Individual samples were hybridized to individual microarrays.

Project description:To address the differential response of the CNS, proteomics was applied in experimental autoimmune encephalomyelitis (EAE) mice and cuprizone (CPZ) mice in two different CNS regions
