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 exon expression changes associated with the disease. In these data sets we include the exon 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. 8 total RNA samples were prepared. A two way ANOVA comparison carried out in Partek Genomics Suite was used to detect differences in exon expression in the spinal cord of female lewis rats with MBP induced EAE and age matched healthy controls.

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.

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:Vaccination with naked DNA encoding myelin basic protein represents a promising therapeutic strategy in multiple sclerosis (MS). In this study, we assessed the potential of vaccination with a DNA construct coding for the myelin oligodendrocyte glycoprotein (MOG), an important candidate autoantigen in MS, to induce tolerance and protect against experimental autoimmune encephalomyelitis (EAE). Herein, we demonstrated that MOG-DNA vaccination reduced the clinical and histopathological signs of EAE when administered in both prophylactic and therapeutic settings. Further mechanistic experiments revealed that the protective effects of MOG-DNA vaccines were associated with a reduction of antigen-specific Th1 and Th17 cellular immune responses and expansion of regulatory T cells in periphery, and up-regulation in the central nervous system of genes encoding neurotrophic factors and proteins involved in remyelination. These results may set the rationale for the use of MOG-based DNA vaccines to induce tolerance in MS patients. We analyzed brain and spinal cord samples from five treated and five control mice

Project description:We performed micrarrays to investigate neuronal gene expression changes during acute inflammatory CNS axon injury using the murine myelin oligodendrocyte glycoprotein 35-55 (MOG35-55)-induced experimental autoimmune encephalomyelitis (EAE) model. The present study was assigned to assess the direct and indirect endogenous neuronal response to spinal axonal injury in the motor and sensory cortex.
