Project description:In experimental autoimmune encephalomyelitis (EAE), a model for multiple sclerosis (MS), induction generates successive waves of clonally expanded CD4+, CD8+, and gd+ T cells in the blood and central nervous system, similar to gluten challenge studies of Celiac patients. In MS patients, we also observe major expansions of CD8+ T cells. In EAE, we find that most expanded CD4+ T cells are specific for the inducing myelin peptide MOG35-55 but in contrast, peptide ligands derived from a yeast peptide-MHC display library for some of the clonally expanded CD8+ T cells inhibit disease by suppressing the proliferation of MOG-specific CD4+ T cells. These results suggest the induction of autoreactive CD4+ T cells triggers an opposing mobilization of regulatory CD8+ T cells.

Gene expression of murine iDCs isolated from tolerized MOG35-55-infused/MOG35-55-immunized or MOG35-55-immunized mice

Project description:Recent data from our group, demonstrate that infusion of myelin oligodendrocyte glycoprotein (MOG35-55) peptide, leads to induction of MOG35-55-specific Tregs and subsequent suppression of Experimental Autoimmune Encephalomyelitis (EAE), the mouse model of multiple sclerosis. Amelioration of EAE was accompanied by reduced MOG-specific Th1 and Th17 responses in the draining lymph nodes (dLNs). Phenotypic analysis of the dLNs of MOG-infused mice revealed a significant Treg-mediated reduction in the recruitment of 7AAD-CD3-CD19-CD11c+CD11bhighGr-1+ iDCs compared to non-infused control immunized mice. Focusing on the delineation of novel molecules/genes that are involved in the MOG-specific Treg-mediated suppression of autoimmune responses, we have isolated highly purified iDCs from MOG infused and non-infused control immunized mice. Gene expression profiles of iDCs isolated from tolerized or immunized mice. Affymetrix MG 430 2.0 whole genome arrays were performed in triplicates for tolerized iDCs and immunized iDCs (6 arrays in total, 5 of them were analyzed). To obtain genes significantly regulated in iDCs upon tolerization with MOG35-55, the expression profiles of iDCs isolated from tolerized or immunized mice were compared to each other. After total RNA extraction, reverse transcription, cDNA extraction, the biotinylated cRNA was transcribed, fragmented, and 15 µg cRNA hybridized to the 6 GeneChip arrays: Group1 iDCs isolated from tolerized mice, Group2 iDCs isolated from immunized mice.

Gene expression in brain tissue from MOG-immunized wild-type or C57BL/6Je/e mice at disease maximum.

Project description:Neuroprotective effects of NDP-MSH. We have characterized the signaling down-stream of melanocortin-1 receptor ligation to identify pathways mediating neuroprotective effects of NDP-MSH using transcriptional profiling. In this data set we included the expression data obtained from mouse brain tissue (MOG-immunized wild-type or C57BL/6Je/e mice at disease maximum, d14 after immunization). The data were used to obtain differentially regulated genes in wild-type or C57BL/6Je/e mice upon systemic NDP-MSH treatment.

MOG-encoding DNA vaccines ameliorate EAE and display neuroprotective effects in treated mice summary

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

Comparative genomic hybridization of experimental autoimmune encephalomyelitis (EAE)-susceptible DA and EAE-resistant PVG rat strains stimulated with myelin oligodendrocyte glycoprotein (MOG) to identify the alternative splicing.

Project description:Experimental autoimmune encephalomyelitis (EAE)-susceptible DA and EAE-resistant PVG rats were immunized with myelin oligodendrocyte glycoprotein (MOG) to induce an autoimmune response.<br>Seven days later draining inguinal lymph nodes were removed. 2 conditions were examined: 'ex vivo' and 'MOG restimulated', which involved 24hrs of incubation with an encephalogenic MOG 91-108 peptide.

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).
