Evaluation of Beclin-1 and Atg5 genes expression levels in peripheral blood cells of patients with rheumatoid arthritis
Background: Rheumatoid arthritis (RA) is a chronic inflammatory autoimmune disease, which primarily affects the joints. During RA development, T cells and other immune cells are recruited to the synovial tissue and promote RA. Autophagy is a process in which intracellular organelles and compounds are degraded. Autophagy as a regulator of cell homeostasis can affect immune cells activation and c...
متن کاملComparative Measurement of Rheumatoid Factor in Serum and Synovial Fluid of Rheumatoid Arthritis Patients by ELISA and Latex-Agglutination Test
Rheumatoid factors (RF) are autoantibodies with specificity for the Fc portion of human IgG. Production of RF is a characteristic feature of rheumatoid arthritis (RA) and is detectable in high titer in about 90% of these patients. In this study, we measured total IgM, IgA, IgMRF and IgARF in serum and synovial fluid of 45 RA patients by ELISA and the results were compared with those obtained b...
متن کاملTumour necrosis factor in serum and synovial fluid of patients with active and severe rheumatoid arthritis.
Fifteen serum samples and 29 synovial fluids of patients with rheumatoid arthritis (RA) were examined for the presence of tumour necrosis factor (TNF). The assay for TNF was based on the cytotoxic activity of this cytokine for human melanoma cells in tissue culture. High concentrations of TNF were found in serum samples of patients with severe RA, who had increased erythrocyte sedimentation rat...
متن کاملStimulation by interleukin-7 of mononuclear cells in peripheral blood, synovial fluid and synovial tissue from patients with rheumatoid arthritis.
To determine how interleukin-7 (IL-7) affects the proliferation of T cells in patients with rheumatoid arthritis (RA), we evaluated the response of mononuclear cells (MNC) obtained from their peripheral blood (PB), synovial fluid (SF) and synovial tissue (ST) to stimulation by recombinant IL-7 and interleukin-2 (IL-2). Each cytokine was administered alone or combined with phytohemagglutinin (PH...
متن کاملTumour necrosis factor-alpha, interleukin-2 soluble receptor and different inflammatory parameters in patients with rheumatoid arthritis.
BACKGROUND AND AIMS Although the participation of cytokines in the pathogenesis of rheumatoid arthritis (RA) seems to be unequivocal, their relationship with current serum markers of this disease is not clear. The present study analyses whether there is any correlation between the levels of tumour necrosis factor-alpha (TNF-alpha), interleukin-2 soluble receptor (sIL-2R) and the concentrations ...
