The diverse actions of macrophage migration inhibitory factor (MIF) within the immuno-neuroendocrine system are yet to be fully understood, but it is clear that MIF plays a pivotal role in the regulation of both the innate and adaptive immune response. An emerging body of data presently indicates that MIF's position within the cytokine cascade is to act in concert with glucocorticoids to control the 'set point' and magnitude of the immune and inflammatory response. In this article we will review the actions of MIF within the immune system and discuss the overlapping and contrasting aspects of MIF and glucocorticoid biology. In particular we will focus on the role of MIF within the immuno-neuroendocrine interface and suggest molecular mechanisms by which MIF may counter-regulate glucocorticoid function. Finally we will discuss emerging evidence that functional MIF gene-promoter polymorphisms render one susceptible to elevated MIF expression, and the development of an exaggerated immune/inflammatory response that potentiates the progression to chronic inflammatory disease.

ABSTRACT

Stress provokes a cohort of homeostatic reflexes by the central nervous, the immune as well as the metabolic control systems of the body. These powerful adaptive responses, which can cause a collapse of body homeostasis in the absence of feedback inhibition, are suppressed by adrenal glucocorticoid hormones. A prominent and physiologically significant early action of glucocorticoids that requires the induction of newly synthesized messenger RNA and protein is the suppression of ACTH release by anterior pituitary corticotroph cells. It is demonstrated here that glucocorticoids inhibit stimulated ACTH secretion in pituitary corticotroph tumour (AtT-20) cells by reducing stimulus-evoked intracellular free calcium transients. Thus, the data show for the first time that intracellular calcium signals may be modified by rapidly induced proteins. It is proposed that this is a general mechanism that underlies the early inhibitory effects of glucocorticoids during stress in various types of cell.

The immunological and neuroendocrine properties of macrophage migration inhibitory factor (MIF) are diverse. In this article we review the known cellular, molecular and genetic properties of MIF that place it as a key regulatory cytokine, acting within both the innate and adaptive immune responses.The unexpected and paradoxical induction of MIF secretion by low concentrations of glucocorticoids is explored. The role of MIF as a locally acting modulator of glucocorticoid sensitivity within foci of inflammation is also discussed. MIF has no homology with any other pro-inflammatory cytokine and until recently lacked a recognised transmembrane receptor. MIF has also been shown to be directly taken up into target cells and to interact with intracellular signalling molecules, including the Jun activation domain-binding protein Jab-1.Comprehensive analysis of the MIF gene has identified important functional polymorphisms and a series of genetic studies has revealed both association and linkage of MIF with inflammatory diseases. Altered MIF regulation may therefore be pivotal to acquiring chronic inflammation following an innate immune response.
