The effects of interleukin-1 beta (IL-1 beta), interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF alpha) and granulocyte-macrophage colony-stimulating factor (GM-CSF) on DNA synthesis of rabbit synovial cells were studied. IL-1 beta 1000-10,000 U.ml-1, IL-6 10-1000 U.ml-1, TNF alpha 0.5-50 U.ml-1 and GM-CSF 1-100 ng.ml-1 concentration-dependently stimulated DNA synthesis in rabbit synovial cells in culture. Leflunomide (LFM) and its metabolite A77 1726 elicited an inhibitory effect on such cytokine-induced DNA synthesis of synovial cells. These results suggested that IL-1 beta, IL-6, TNF alpha and GM-CSF play a key role in the pathogenesis of rheumatoid arthritis. Inhibition of cytokine-induced proliferation of synovial cells by LFM may partially explain its antirheumatic activity.
