abstract

  • Mononuclear cells (MNC) in synovial fluids from patients with rheumatoid arthritis and other arthropathies differ clearly from MNC in peripheral blood. Typically the ratio of CD4(+)-/CD8+ lymphocytes is inverted and the response to mitogens/cytokines (IL-1/IL-2) is impaired. Active TGF-beta (transforming growth factor beta) was found to account for these abnormalities, and the major isoform was identified as TGF-beta 2.
