Enhanced expression of tumor necrosis factor receptor mRNA and protein in mononuclear cells isolated from rheumatoid arthritis synovial joints.
We previously proposed the hypothesis that the pro-inflammatory cytokine tumor necrosis factor-alpha (TNF-alpha) plays a pivotal role in the pathogenesis of rheumatoid arthritis (RA) based on our observations that it is the dominant inducer of interleukin-1 (IL-1) and granulocyte-macrophage colony-stimulating factor (GM-CSF) production in RA synovial joint mononuclear (MNC) cells in culture. Since TNF-alpha acts via two membrane receptors, we have extended those studies to investigate the dis...Expand abstract
