Abstract: Purpose: The pathogenesis of Rheumatoid Arthritis (RA) is not well understood. Looking for three mediators [Soluble Interleukine 2 Receptor (SIL2R), ß2 Microglobulin (ß2M) and Tumor Necrosis Factor α (TNF α)] in RA patients sera and synovial fluid (SF) may clear some aspects of it. Methods: The above named mediators were estimated in 72 RA patient sera and SF, 13 patient with osteoarthritis (as patient control) and 130 blood donor (as normal ...
CD5-POSITIVE B CELLS In Rheumatoid Arthritis Patients.
Abstract: The concept that rheumatoid arthritis (RA) is an autoimmune disease is supported by variety of autoantibodies in patient's serum. The most important of these are rheumatoid factors (RFs), antibodies that react with the patient's own Ig. It has been suggested that IgM-RF plays a role in disease pathogenesis. The main source of IgM-RF are B cells that express the pan T-cell marker, CDS: We conducted this study to test the ...
