Detailed Description
Uveitis describes inflammation that exists in the uveal tract, but the disease course has such a variety of manifestations. Uveitis (intraocular inflammatory diseases) includes sight-threatening diseases such as Behcet disease, birdshot retinochoroidopathy, Vogt-Koyanagi-Harada, sympathetic ophthalmia and ocular sarcoidosis, and may be of infectious or autoimmune etiology.
CD4+ CD25+ Tr cells play a key role in the maintenance of peripheral self-tolerance by inhibiting the activation and proliferation of unreactive T cells. In addition to a direct suppressor effect on CD4+CD25+ Tr cells. CD4+CD25+ Tr cells may regulate the immune response through dendritic cell. Like cytotoxic T-lymphocytes and natural killer cells,activated human CD4+CD25+ Tr cells display perforin-dependent cytoxicity against autologous target cell, including activated CD4+ and CD8+ T cells.
Experimental autoimmune uveoretinitis (EAU) is a model of uveitis. Regulatory T cells in the uveitis are currently thought to be the etiologic agent of uveitis because IFN-γ,IL-2(interleukin-2),TNF(Tumor Necrosis Factor alpha) levels are elevated in the retina during uveitis Following stimulation with IL-2 expression was upregulated in PBMC(peripheral blood mononuclear cell) of healthy subjects and patients with scleritis or uveitis. By ELISA, we confirmed that IL-2 induced the secretion of the protein in human PBMC and in mouse CD4+T cells. Experiment found, by an intracellular cytokine analysis assay, that the IFN-γ,IL-2,TNF expressing cells were predominantly CD4+T cells with a memory phenotype. Consistent with our RNA data, the percentage of CD4+T cells was higher in scleritis patients than in healthy subjects.
We analyzed peripheral blood of thirty uveitis patients enrolled in Department of Ophthalmology, Xijing Hospital clinical trials. The demographics of the patients, including age, sex, diagnosis and medications at time of sample collection .
Biospecimen Description:
Experimental: A Drug: prednisone profess to convinced 1-1.5mg/Kg.d Experimental: B Drug: methotrexate profess to convinced 7.5-15mg/w, concoction prednisone profess to convinced 0.5-1mg/Kg.d Methods CD4+CD25+ Tr cells, CTLA-4 and an intracellular cytokine analysis assay that the IFN-γ,IL-2,TNF expressing cells were measured in 30 uveitis patients before and after 1 month,3 months of prednisone and methotrexate.
Cytokine assays. For intracellular cytokine detect, CD4+T cells were cultured as indicated above and restimulated for 5h with 1mg/ml phorbol 12-myristate 13-acetate (PMA) and ionomycin (1mg/ml) in the presence of Golgistop, we added antibodies (IFN-γ,IL-2,TNF). We performed cytokine staining using BD Biosciences and analyzed samples by flow cytometry.
