- Abstract
Summary Systemic lupus erythematosus (SLE) is the prototype of a cluster of diseases that are characterized by a loss of self tolerance and chronic inflammation in organs including skin, kidney, brain and joints. Researchers have long debated the varying contributions of the components of the immune system to the pathogenesis of SLE, but the emigration of leucocytes from the microcirculation, and the subsequent tissue inflammation mediated by these inflammatory cells, are key features of chronic inflammation seen in SLE. Macrophage migration inhibitory factor (MIF) is a broad-spectrum pro-inflammatory cytokine. We hypothesize that MIF is an important inflammatory mediator in the perpetuation of immune activation in SLE, via its effects on activation of T and B cells, and endothelial and effector cells. As MIF exerts anti-apoptotic effects, it may also play a role in promoting abnormal survival of autoreactive lymphocytes, thus perpetuating autoimmune reactivity. In addition, MIF has a unique relationship with glucocorticoids, in that MIF can override the effects of glucocorticoids and may be important in steroid resistance. By virtue of its pluripotent functions, we propose that MIF may be a critical mediator of inflammation and damage in SLE, and that targeting of MIF may offer therapeutic benefits in this disease.
