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).

Project description:Cells were prepared from draining lymph nodes (dLN) from naïve C57BL6/N female mice, as well as from C57BL6/N female mice at day 1 and day 3 after subcutaneous immunization with MOG(35-55) emulsified in Complete Freund’s adjuvant (CFA). Some mice received the CpG-B-1826 (50 microg; TCCATgACgTTCCTgACgTT; TIB MOLBIOL Syntheselabor GmbH), which was added to the MOG(35-55)/CFA mixture before emulsification. Cells from dLN were directly lysed in 350 microlitres RLT buffer containing 1% beta-mercaptoethanol (Invitrogen). Mice were 6-10 weeks of age at the time of immunization. The goal was to identify genes differentially expressed between dLN cells from mice immunized with the classical EAE protocol versus mice immunized with the addition of CpG-B-1826 to the immunization cocktail in order to gain some insights into the immune-modulatory effect of this treatment using an unbiased approach.

Project description:Mice were immunized with either MOG35-55 in CFA or with CFA alone and 14 days later PLN cells were isolated and stimulated in vitro with MOG35-55 for 3 days followed by CD4+ T cell sorting. Microarray analysis of miRNA expression profiles was performed comparing sorted CD4+ T cells from MOG35-55 in CFA immunized mice to CD4+ T cells from mice immunized with CFA alone.

Project description:We found that a number of Tfh cells downmodulated BCL6 protein after their development, and we sought to compare the gene expression between BCL6-hi Tfh cells and BCL6-low Tfh cells. CD4+ T cells were sorted from immunized and non-immunized mice for RNA extraction and hybridization on Affymetrix microarrays. Bcl6yfp/+ OT-II cells were transferred to congenic recipient mice, and immunized with NP-OVA in CFA subcutaneously. Seven or ten days after immunization, cells were collected from draining lymph nodes, and sorted on FACSAria by the expression of CXCR5, PD-1 and BCL6-YFP. Naive CD4+ T cells were CD4+ CD44lo CD62Lhi cells from unimmunized 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.

Project description:Synovial antigen arrays were probed with 1:150 dilutions of plasma derived from SJL mice immunized with fibrinogen emulsified in CFA or with CFA alone. Autoantibody binding was detected with a Cy3-conjugated goat-anti-mouse IgG/M secondary antibody. SAM was applied to identify antigens with statistically significant differences in array reactivity between FIA and CFA control plasma (q < 0.01) obtained from mice before boosting. The SAM hits were subjected to hierarchical cluster analysis and are displayed as a heatmap. Synovial array profiling of FIA plasma demonstrated autoreactive B-cell responses against peptides representing native fibrinogen, and B-cell epitope spreading resulting in additional targeting of citrullinated fibrinogen in the samples obtained before boosting. Custom-spotted protein slides were probed with plasma samples from individual mice. Four slides were probed with plasma derived from mice immunized with CFA and six slides were probed with plasma derived from mice immunized with fibrinogen emulsified in CFA.

Microarray analysis of miRNA expression profiles was performed comparing sorted CD4+ T cells from MOG35-55 in CFA immunized mice to CD4+ T cells from mice immunized with CFA alone. The data are from magnetic beads sorted CD4+ T cells from peripheral lymph nodes from 5 pooled animals per data point

Project description:HLA DRB1*15:01 is overrepresentated in Parkinson's disease patients and binds with high affinity to the ⍺-synuclein peptide, 32-46. Immunization of humanized mice expressing HLA DRB1*15:01 with ⍺-syn32-46 induces enteric phenotypes similar to those of prodromal Parkinson's disease. We collected the small intestines from HLA mice immunized with either Complete Freund's Adjuvant (CFA) with ⍺-syn32-46 or CFA alone, sorted the CD45+ immune cells, then performed single-cell RNA sequencing to evaluate gene expression at single cell resolution.
