Retinal endothelial cell phenotypic modifications during experimental autoimmune uveitis: a transcriptomic approach

Project description:Background: Blood-retinal barrier cells are known to exhibit a massive phenotypic change during experimental autoimmune uveitis (EAU) development. In an attempt to investigate the mechanisms of blood-retinal barrier (BRB) breakdown at a global level, we studied the gene regulation of total retinal cells and retinal endothelial cells during non-infectious uveitis. Methods: Retinal endothelial cells were isolated by flow cytometry either in Tie2-GFP mice (CD31+ CD45- GFP+ cells), or in wild type C57BL/6 mice (CD31+ CD45- endoglin+ cells). EAU was induced in C57BL/6 mice by adoptive transfer of IRBP1-20-specific T cells. Total retinal cells and retinal endothelial cells from naïve and EAU mice were sorted and their gene expression compared by RNA-Seq. Protein expression of selected genes was validated by immunofluorescence on retinal wholemounts and cryosections and by flow cytometry. Results: Retinal endothelial cell sorting in wild type C57BL/6 mice was validated by comparative transcriptome analysis with retinal endothelial cells sorted from Tie2-GFP mice, which express GFP under the control of the endothelial-specific receptor tyrosine kinase promoter Tie2. RNA-Seq analysis of total retinal cells mainly brought to light upregulation of genes involved in antigen presentation and T cell activation during EAU. Specific transcriptome analysis of retinal endothelial cells allowed us to identify 82 genes modulated in retinal endothelial cells during EAU development. Protein expression of 5 of those genes (serpina3n, lipocalin 2, ackr1, lrg1 and lamc3) was validated at the level of inner BRB cells. Conclusion: Those data not only confirm the involvement of known pathogenic molecules but further provide a list of new candidate genes and pathways possibly implicated in inner BRB breakdown during non-infectious posterior uveitis.

Single-cell transcriptomic analysis of retinal immune regulation and blood-retinal barrier function during experimental autoimmune uveitis

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.

Murine CD4+ T cells: naive vs. experimental autoimmune uveitis

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.

Chronic sleep deprivation promotes experimental autoimmune uveitis through STAT1 phosphorylation, ISG15 expression and enhanced pathogenicity of macrophages

Project description:Autoimmune uveitis (AU) is a severe intraocular inflammatory disease driven by dysregulated T-cell immunity and macrophage activation, leading to retinal tissue damage. Experimental autoimmune uveitis (EAU), an animal model, closely mimics human AU, highlighting the role of macrophages in inflammation and immune regulation. Chronic sleep deprivation (CSD), caused by prolonged circadian rhythm disruption, further exacerbates immune dysfunction by activating microglia and enhancing inflammation. This study investigates the combined impact of EAU and CSD on retinal transcriptomics, focusing on immune and inflammatory pathways, providing insights into the interaction between circadian rhythm disruptions and autoimmune uveitis progression.

Effector T cells driving monophasic vs relapse/remitting experimental autoimmune uveitis show unique pathway signatures

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.

Proteome changes in retinal Mueller glial cells from a spontaneous equine model for autoimmune uveitis compared to healthy controls

Project description:Retinal Müller glial cells (RMG) play a central role in retinal neuroinflammation, actively participating in the immune response and adopting a dynamic inflammatory phenotype. However, the precise functions of RMG in retinal inflammation remain incompletely understood. In this study, we investigated the proteome of RMG isolated from healthy horses and horses affected by equine recurrent uveitis (ERU). ERU serves as a unique spontaneous model of autoimmune uveitis, exhibiting key clinical and pathophysiological features observed in humans, such as a relapsing-remitting course of disease and a CD4+ T cell-driven autoimmune etiology [1, 2]. To gain insights into the molecular landscape of RMG in a spontaneous animal model of autoimmune uveitis and their potential contribution to retinal autoimmune neuroinflammation, we used discovery proteomics for the analysis of RMG from healthy horses and horses with ERU. Our data are not only relevant to veterinary medicine but also hold significant translational value for human ophthalmology as well.

equine CD4+ T cells show changed membrane protein expression in autoimmune uveitis

Project description:Through this comparative proteomic study of equine CD4+ cells 376 membrane proteins could be identified. Several proteins showed changed abundance in horses affected by a spontaneous autoimmune disease (equine recurrent uveitis, ERU). Findings provide novel knowledge about changes in the CD4+ immune cell membrane proteome in a spontaneously and naturally occurring autoimmune disease in horses. The data is highly relevant for veterinary medicine and has proven translational quality for autoimmune uveitis in man.
