Apoptotic Neutrophils Release Macrophage Migration Inhibitory Factor upon Stimulation with Tumor Necrosis Factor-α

Macrophage Migration Inhibitory Factor

Regulatory role of C5a on macrophage migration inhibitory factor release from neutrophils.

There is evidence that C5a and macrophage migration inhibitory factor (MIF) both play important roles in experimental sepsis. Humans with sepsis also show elevated levels of both mediators in the blood. Regulation of MIF during sepsis is poorly understood. We now demonstrate that neutrophil depletion greatly reduced serum MIF levels in rats and mice during the onset of sepsis after cecal ligati...

Macrophage-derived Tumor Necrosis Factor-α mediates diabetic renal injury

Monocyte/macrophage recruitment correlates strongly with the progression of diabetic nephropathy. Tumor necrosis factor-α (TNF-α) is produced by monocytes/macrophages but the direct role of TNF-α and/or macrophage-derived TNF-α in the progression of diabetic nephropathy remains unclear. Here we tested whether inhibition of TNF-α confers kidney protection in diabetic nephropathy via a macrophage...

Correlation between urine macrophage migration inhibitory factor (MIF)/creatinine ratio and time after kidney transplantation

 Abstract  Background: Despite the long-standing association of macrophage migration inhibitory  factor (MIF) with delayed-type hypersensitivity response, the potential role  of MIF in chronic allograft nephropathy is unknown. The association between upregulation of MIF expression, macrophage and T cell infiltration and the severity of  chronic allograft nephropathy suggests that MIF may be an ...

Glucocorticoid Suppression of Macrophage Migration Inhibitory Factor

The ability of hydrocortisone to modify antigen-mediated inhibition of macrophage migration, an in vitro correlate of cellular immunity in the guinea pig, was investigated. Only the glucocorticoids, hydrocortisone and dexamethasone, significantly blocked migration inhibitory factor (MIF) activity in pharmacologic concentrations. Hydrocortisone had no effect on antigen "processing" by macrophage...
