RHEUMATOID FACTOR AND THE PATHOGENESIS OF RHEUMATOID ARTHRITIS

Rheumatoid Factor and the Pathogenesis of Rheumatoid Arthritis

In analogy with the two categories of reactants which are used in the serological tests for the unusual category of macroglobulins called rheumatoid factor, two fluorescent reactants have been prepared for the detection of rheumatoid factor in situ in tissue sections: fluorescent antigen-rabbit antibody (immune) complex, in the present study, and fluorescent aggregated human gamma-globulin, in ...

Comparative 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...

Pathogenesis of Rheumatoid Arthritis

[Pathogenesis of rheumatoid arthritis].

Rheumatoid arthritis (RA) is an autoimmune systemic disease that primarily affects joints. Etiology and the pathogenesis of RA are complex, involving many types of cells, among others macrophages, T and B cells, fibro- blasts, chondrocytes and dendritic cells. Despite well documented role of many genes and epigenetic modifications in the development and evolution of the disease, in most RA pati...
