Project description:The possibility of generating neural stem/precursor cells (NPCs) from induced pluripotent stem cells (iPSCs) has opened a new avenue of research that might nurture bench-to bedside translation of novel and more efficient protocols of cell transplantation in central nervous system (CNS) myelin disorders. We have performed the transcriptome analysis in the spinal cord of mice with sham treated Experimental Animal Encephelomyletis (EAE), miPSC-NPC treated EAE mice and naive mice, in order understand the gene expression changes related to the miPSC-NPC treatment.
Project description:Assessment of whether endogenous IFN-I exerts genome-wide gene expression changes in splenic CD3 T cells and spinal cord during priming phase of EAE, we performed transcriptome analysis on T cells and spinal cord derived from 3-month old IFNAR1Texcl and WT animals on day 10 upon EAE induction.
Project description:Microarrays were used to identify genes that were differently expressed in mouse spinal cord as a resut of experimental autoimmune encephalomyelitis (EAE), which is a model for demyelinating disease. Mice were injected with PLP peptide or vechicle.

Project description:There are two aims in this study – (1) To figure out the pathogenic sub-populations of CD4+ T cells in the spinal cord of EAE model; and (2) by comparing the gene expression profile of pathogenic Th17 cells in EAE model to that of the non-pathogenic Th17 cells induced by SFB in SILP, to identify genes candidates that are potentially selectively essential to pathogenic ones.
Project description:The study assessed the efficacy of R-flurbiprofen in experimental autoimmune encephalomyelitis (EAE) models of multiple sclerosis in mice. R-flurbiprofen, also known as tarenflurbil, is the R-enantiomer of the cyclooxyygenase inhibitor S-flurbiprofen. It is ineffective in terms of cyclooxygenase inhibition and has no relevant toxicity in humans. Oral R-flurbiprofen prevented and attenuated primary progressive EAE in C57BL6/J mice and relapsing-remitting EAE in SJL mice, even if the treatment was initiated on or after the first flare of the disease. R-flurbiprofen reduced immune cell infiltration and microglia activation and inflammation in the spinal cord, brain and optic nerve and attenuated myelin destruction and EAE-evoked hyperalgesia. R-flurbiprofen treatment increased CD4+CD25+FoxP3+ regulatory T-cells, CTLA4+ inhibitory T-cells and interleukin-10, whereas the EAE-evoked upregulation of pro-inflammatory genes in the spinal cord was strongly reduced (Sentrix6 results). The effects were associated with an increase of plasma and cortical endocannabinoids but decreased spinal prostaglandins, the latter likely due to R- to S inversion. The promising results suggest potential efficacy of R-flurbiprofen in human MS. To assess effects of R-flurbiprofen on EAE evoked gene regulations in the spinal cord a genome wide expression analysis was performed using Illumina Sentrix 6 v2 BeadChips. For the microarray study female C57BL6/J mice were immunized according to a standard protocol using the Hooke KitM-bM-^DM-" MOG35-55/CFA emulsion PTX (EK-2110, Hooke Labs, St Lawrence, MA), which contains 200 M-BM-5g myelin oligodendrocyte glycoprotein (MOG) 35-55 emulsified in 200 M-BM-5l Complete FreundM-bM-^@M-^Ys Adjuvant (CFA). The emulsion was injected subcutaneously at two sites followed by two intraperitoneal (i.p.) injections of 200 ng pertussis toxin (PTX) in phosphate buffered saline (PBS), the first 1-2 h after MOG35-55, and the second 24 h after MOG35-55. Control mice received CFA without MOG35-55 (sham mice). Treatment with R-flurbiprofen or vehicle (n = 12 per group) was started 5 days after immunization and was administered continuously via the drinking water up to the end. Spinal cords were dissected out during the flare of the disease, day 16 after immunization. For microarray analysis, total RNA was extracted from homogenizedlumbar spinal cord tissue with Trizol reagent, followed by clean-up and DNase I treatment with QIAGEN RNeasy mini kit. RNA quality was checked (Nanodrop ND-1000, Agilent 2100 Bioanalyzer), and subsequently biotinylated and hybridized to Mouse Sentrix-6 V2 Expression BeadChips (Illumina). Each sample consisted of pooled lumbar spinal cord tissue from 3 animals and 3 replicate samples were analyzed per group, i.e. the analysis is based on 9 mice per group. Groups were CFA-control with vehicle treatment, CFA-control with R-flurbiprofen, EAE-vehicle and EAE-R-flurbiprofen treatment. Treatment was started 5 days after immunization. For dissection, pairs were matched according to the clinical scores. QC, labeling, hybridization and raw data evaluation and normalization were done according to standard protocols at the core facilities of the Deutsche Krebsforschungszentrum, Heidelberg, Germany.
