Proteomic Identification of Macrophage Migration-inhibitory Factor upon Exposure to TiO2 Particles

Proteomic identification of macrophage migration-inhibitory factor upon exposure to TiO2 particles.

Inhalation of particulate matter aggravates respiratory symptoms in patients with chronic airway diseases, but the mechanisms underlying this response remain poorly understood. We used a proteomics approach to examine this phenomenon. Treatment of epithelial cells with BSA-coated titanium dioxide (TiO(2)) particles altered 20 protein spots on the two-dimensional gel, and these were then analyze...

Macrophage Migration Inhibitory Factor

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...

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 ...

Macrophage Migration Inhibitory Factor in Protozoan Infections

Macrophage migration inhibitory factor (MIF) is a cytokine that plays a central role in immune and inflammatory responses. In the present paper, we discussed the participation of MIF in the immune response to protozoan parasite infections. As a general trend, MIF participates in the control of parasite burden at the expense of promoting tissue damage due to increased inflammation.
