Project description:Uveitis is a severe autoimmune disease characereized by retinal inflammation, whicn brings harms to the visual function of the patients. We found that nimodipine could protect annimals from experimental autoimmune uveitis. To further clarify the possible mechanism through which nimodipine exerted effect, we performed genomic expression profiling of CD3+ T cells in EAU model and nimodipine treated group.

Project description:miRNA expression profiling of CD4+ T cells comparing naïve mice and experimental autoimmune uveitis (EAU) mice. EAU was induced by immunization of retinal antigen (IRBP1-20) in complete Freund’s adjuvant (CFA). CD4+ T cells were isolated and purified from the spleen and draining lymph nodes 13 days after immunization.

Project description:Experimental autoimmune uveitis (EAU) in Lewis rats is a model for the clinical heterogeneity of human uveitis. The autoantigens inducing disease in the rat are also seen in human disease. Depending upon the specific autoantigen used, the experimental disease course can be either monophasic or relapsing/remitting and appears to be dictated by the T cell effector phenotype elicited. We investigated potential differences between monophasic and relapsing/remitting effector T cells using transcriptomic profiling and pathway analysis. RNA samples isolated from three independent T cell lines derived from each specificity where analyzed by microarrays. Microarray data was used to obtain transcriptomic changes reflecting signal transduction pathway dysregulation. Keywords: Two group comparison Comparison of two types of cell lines of two different antigen specificities.

Project description:Background & Aims: The influences of the maternal diet during gestation has been suggested to be involved in the development of different aspects of the metabolic syndrome. In our mouse model we characterised the role of maternal western diet in the development of non-alcoholic fatty liver disease (NAFLD) in the offspring. Methods: Female mice were fed either a western (W) or low-fat control (L) semi-synthetic diet before and during gestation and lactation. At weaning, male offspring were assigned either the W or the L diet, generating four experimental groups: WW, WL, LW and LL offspring. Biochemical, histological and epigenetic indicators were investigated at 29 weeks of age. Results: Male offspring exposed to prenatal western style diet and to a post-weaning W diet (WW) showed hepatomegaly combined with increased hepatic cholesterol and triglycerides accumulation, compared to LW offspring. This was associated with up-regulation of de novo lipid synthesis and dysregulation of beta oxidation and lipid storage. Elevated hepatic transaminases and increased expression of Tnfa, Cd11, Mcp1 and Tgfb underpin the severity of liver injury. Histological analysis supported the presence of steatohepatitis in the WW offspring. In addition alterations in DNA methylation in key metabolic genes (Ppara, Insig, Fasn) were detected. Conclusion: Maternal dietary fat intake during critical developmental phases programs susceptibility to liver disease in mouse offspring. This was mediated by shifts in lipid metabolism and inflammatory response. Long lasting epigenetic changes may underlie this dysregulation 4 groups of 6 male mouse were analysed , 1 experimental and 1 biological outlier was excluded , so n=6,5,5,6 in the 4 groups (LL,LW,WL,WW)

Project description:In this study, we found that microglia have a considerable number of cells compared to T cells, indicating an equally critical role of microglia in the progression of autoimmune uveitis. We further identified a specific microglial subpopulation expressed with high levels of CD74 and CCL5, which may be directly related to inflammation regulation in autoimmune uveitis and named inflammation-associated microglia (IAMs). Decreasing the number of IAMs by gene regulation methods or CD74/CCL5 neutralizing antibodies effectively reduced inflammation in EAU mice and delayed disease progression. A mechanistic study indicated that the CD74/CCL5 axis was mainly responsible for the regulation of the immune response in autoimmune uveitis. The intracytoplasmic domain of CD74 (CD74–ICD) may be cleaved by the SPPL2A protease and then activate the NF-kB-dependent inflammation pathway in IAM, resulting in the production of CCL5, which recruits peripheral T cells into the retina and causes an inflammatory burst in autoimmune uveitis mice. Decreasing the level of CD74 or CCL5 could effectively reduce uveitogenic T cell infiltration and relieve the autoimmune response in EAU mouse models, indicating the potential therapeutic value of CD74 and CCL5 in autoimmune uveitis.
