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: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:Uveitis is characterised by breakdown of the blood-retinal barrier (BRB), allowing infiltration of immune cells that mediate intraocular inflammation, which can lead to irreversible damage of the neuroretina and the loss of sight. Treatment of uveitis relies heavily on corticosteroids and systemic immunosuppression due to limited understanding of the molecular immune interactions that underpin ocular immune homeostasis. By performing single-cell transcriptomic analysis of whole dissociated mouse retinas with experimental autoimmune uveitis (EAU) versus healthy control, we gained an unbiased appreciation of the immune interactions that drive retinal inflammation in a model of posterior uveitis.

Project description:T-helper 1 responses are involved in the development of many autoimmune diseases such as Multiple sclerosis (MS). MS is a relapse remitting disease that eventually progresses to a progressive neurodegenerative disease. During pregnancy the relapse rate of MS is significantly reduced with peak reduction during the third trimester followed by an increase in relapse rate post-partum. One of the highest expressed hormones during pregnancy is progesterone. Progesterone has been show to have an inhibiting effect on T-cell activation and been proposed to promote a T-regulatory like cell state. To evaluate the influence of progesterone on the chromatin and gene expressive state of T-helper type 1 cells we differentiated primary human naïve T-cell in the presence progesterone with sampling at 0.5, 1, 2, 6 and 24 hours and performed ATAC-seq and RNA-seq.

Project description:Uveitis describes a heterogeneous group of inflammatory eye diseases characterized by infiltration of leukocytes into the uveal tissues. uveitis associated with the HLA haplotype B27 (HLA-B27) is a common subtype of uveitis and a prototypical ocular immune-mediated disease. Local immune mechanisms driving human uveitis are poorly characterized mainly due to the limited available biomaterial and subsequent technical limitations. Here, we provide the first high-resolution characterization of intraocular leukocytes in HLA-B27 positive (n=3) and negative (n=2) anterior uveitis and an infectious endophthalmitis control (n=1) by combining single cell RNA-sequencing with flow cytometry and protein analysis. Ocular cell infiltrates consisted primarily of lymphocytes in both subtypes of uveitis and of myeloid cells in infectious endophthalmitis. HLA-B27 positive uveitis exclusively featured a plasmacytoid and classical dendritic cells (cDC) infiltrate. Moreover, cDCs were central in predicted local cell-cell communication. This suggests a unique pattern of ocular leukocyte infiltration in HLA-B27 positive uveitis with relevance of dendritic cells.

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.
