Abstract

To determine the importance of macrophage migration inhibitory factor (MIF) in the development of arthritis we used an experimental model for rheumatoid arthritis, collagen type II (CII)-induced arthritis in mice. Treatment with neutralizing anti-MIF Abs before immunization of (B10.Q x DBA/1)F1 with CII led to delayed onset and lowered frequency of arthritis. This was associated with lower levels of IgG2a to CII in MIF-depleted mice. The proliferative response to CII was stronger in the anti-MIF-treated mice, whereas no significant effects were seen on Ag-induced IFN-gamma production in response to CII or on the total serum Ab levels in response to CII. These results provide the first experimental evidence of a role for MIF in the pathogenesis of autoimmune disease.

Autoimmune Diseases

Autoimmune diseases occur as a result of an attack by the immune system on the body’s own tissues resulting in damage and dysfunction. There are different types of autoimmune diseases, in which there is a complex and unknown interaction between genetics and the environment. Discover the latest research on autoimmune diseases here.
