Project description:Examined the removal or reduction of circulating miRNAs with apheresis. The levels of expression of a large number of circulating miRNAs were measured in the plasma samples separated by the primary membranes from all 3 patients with systemic lupus erythematosus. This is the first report that circulating miRNAs in peripheral blood can be separated and possibly directly removed using membrane separation apheresis.
Project description:Systemic lupus erythematosus (SLE), also known simply as lupus, is an autoimmune disease. There is no cure for SLE. The mechanism involves an immune response by autoantibodies against a person's own tissues. However, the mechanism underlying imbalance of autoantibodies is not clear. In this experiment, peripheral blood was obtained from normal healthy donors and systemic lupus erythematosus (SLE) patients. Peripheral blood mononuclear cells (PBMC) were separated by Ficoll separation solution. Samples of four (total eight) donors were pooled and Samples of four (total eight) SLE patients were pooled. The aim was to characterize the mRNA profile of SLE patients compared to healthy donors and find the new target of diagnosis or treatment for SLE.
Project description:Gene expression profile studies have identified an interferon signature in whole blood or mononuclear cell samples from patients with systemic lupus erythematosus. This study was designed to determine whether specific lymphocyte and myeloid subsets freshly isolated from the blood of systemic lupus erythematosus patients demonstrated unique gene expression profiles compared to subsets isolated from healthy controls. Experiment Overall Design: The entire study included 67 samples. One CEL file was not available for SLE13_CD4

Project description:Recent studies have shown that alterations in the function of dendritic cells (DCs) are involved in the pathogenesis of systemic lupus erythematosus (SLE). However, the role of DCs participating in SLE remains unclear. We profiled the microRNAs (miRNAs) of LPS-stimulated DCs in SLE patients and found diffentially expressed miRNAs in DCs of such group patients.
Project description:In this experiment, the miRNA profile of microvesicles (MV) released from activated or apoptotic (UV-B treated) T-lymphocytes and their cells of origin was analyzed in both samples obtained from normal healthy donors and systemic lupus erythematosus (SLE) patients. Therefore in short, RNA was isolated of activated and apoptotic (UV-B treated) T-Lymphocytes and corresponding MV of normal healthy individuals and systemic lupus erythematosus (SLE) patients. Samples of four donors each were pooled. The aim was to characterize the miRNA profile of MV dependent on different release stimuli and compare their miRNA-profile to their cells of origin.
