Exogenous soluble tumor necrosis factor receptor type I ameliorates murine experimental autoimmune neuritis.
Tumor necrosis factor (TNF) and its receptor (TNFR) have been strongly implicated in the pathogenesis of autoimmune disease. Soluble cytokine receptors may be shed naturally from cell membranes to inhibit cytokine activity. Experimental autoimmune neuritis (EAN) is a CD4 Th1 cell-mediated animal model of Guillain-Barré syndrome (GBS) in humans. In the present study, we investigated the effects of soluble TNFR type I (sTNFR I) in EAN induced in mice by P0 peptide 180-199 and Freund's complete adjuvant. Our data from two different therapeutic regimens indicate that the administration of sTNFR I effectively ameliorated the clinical and pathological signs of EAN, i.e., decreased its severity, shortened its duration, and reduced inflammatory cell infiltration into the peripheral nervous system. The suppression of clinical EAN was accompanied in vitro by a marked reduction in antigen-specific T-cell proliferation and IFN-gamma synthesis by spleen cells from sTNFR I-treated mice, compared to control mice treated with PBS. These data directly demonstrate a pivotal role for TNF in the development of EAN and also suggest that sTNFR I may have therapeutic potential for alleviating GBS in humans.
