Abstract
Tumor necrosis factor (TNF)-α has an important role in the pathogenesis of autoimmune and inflammatory diseases such as rheumatoid and septic arthritis. The biological effects of TNF-α are mediated by binding to TNF receptors TNFR1 (also known as P60) or TNFR2 (also known as P80). The pre-ligand assembly domain (PLAD) is a portion of the extracellular region of TNFRs that mediates receptor-chain association essential for signaling. We found that soluble versions of PLAD, especially those derived from P60, block the biochemical effects of TNF-α in vitro and potently inhibit arthritis in animal models. Thus, targeting the PLAD may have clinical value in the treatment of human arthritis and other disorders involving receptors of the TNFR superfamily.Cite this article
