Macrophage migration inhibitory factor (MIF) is a secreted protein that activates macrophages, neutrophils and T cells, and is implicated in sepsis, adult respiratory distress syndrome and rheumatoid arthritis. The mechanism of MIF function, however, is unknown. The three-dimensional structure of MIF is unlike that of any other cytokine, but bears striking(More)
Macrophage migration inhibitory factor (MIF) is an important immunoregulatory molecule with a unique ability to suppress the anti-inflammatory effects of glucocorticoids. Although considered a cytokine, MIF possesses a three-dimensional structure and active site similar to those of 4-oxalocrotonate tautomerase and 5-carboxymethyl-2-hydroxymuconate(More)
The subunit structure of human macrophage migration inhibitory factor (MIF) has been studied by preliminary X-ray analysis of wild-type and selenomethionine-MIF and dynamic light scattering. Crystal form I of MIF belongs to space group P2(1)2(1)2(1) and is grown from 2 M ammonium sulfate at pH 8.5. A native data set has been collected to 2.4 A resolution.(More)
Macrophage migration inhibitory factor (MIF) has been reported to interact with glutathione and S-hexylglutathione and to possess glutathione S-transferase activity. However, contrary to these reports, a recent NMR study concluded that MIF shows no affinity for glutathione. Re-examination of the glutathione-MIF interactions indicates that the reported(More)
Growth factor-dependent neurons die when they are deprived of their specific growth factor. This "programmed" cell death (PCD) requires macromolecular synthesis and is distinct from necrotic cell death. To investigate the mechanisms involved in neuronal PCD, we have studied the sequence of events that occur when a neuronal cell line (F-11: mouse(More)
