Macrophage migration inhibitory factor expression in male and female ethanol-fed rats.

چکیده
Macrophage migration inhibitory factory (MIF) regulates macrophage accumulation at sites of injury and can promote the inflammatory response. We studied MIF expression in the intragastric feeding rat model for alcoholic liver injury. Male and age-matched female rats were fed ethanol or dextrose with fish oil. Two groups of male rats were fed medium-chain triglycerides with ethanol or dextrose. Analysis of liver histopathology, lipid peroxidation, endotoxin, mRNA, and immunohistochemistry for MIF, tumor necrosis factor-alpha (TNF-alpha) and interferon-gamma (IFN-gamma) were carried out. Male and female rats fed fish oil and ethanol showed necroinflammatory liver injury and had the highest expression of MIF, TNF-alpha, and IFN-gamma in the liver. Decreased levels of MIF protein were seen in rats with higher endotoxin levels, suggesting that preformed MIF is released into the circulation. MIF is an important mediator of the inflammatory response in alcoholic liver disease and a potential therapeutic target.

Background: Macrophage migration inhibitory factor (MIF) is a key pro-inflammatory cytokine that is secreted by accumulated active macrophages in ectopic tissue of endometriosis. MIF is involved in pathophysiological events of endometriosis, such as angiogenesis and cell proliferation. MIF that stimulates the synthesis of PGE2, leads to over-expression of local estradiol synthesis in endometrio...

Background MIF via its receptor, CD74, initiates a signaling cascade that leads to proliferation and survival of cells. Also, MIF binding to CD74 activates p38 signaling pathways that lead to positive effect on the expression of COX-2. The aim of this study was to evaluate the gene expression profile of MIF, CD74 and COX-2 in normal, ectopic and eutopic endometrium during menstrual cycle. The e...

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 ...

The objective of this research was to evaluate the interference of ethanol consumption by female rats with cytokines involved in the sepsis process and its correlation with mortality, the main outcome of sepsis. Female Wistar rats in estrus phase were evaluated in three experiments. Experiment 1 (n=40) was performed to determine survival rates. Experiment 2 (n=69) was designed for biochemical a...
متن کاملLack of macrophage migration inhibitory factor regulation is linked to the increased chronotropic action of angiotensin II in SHR neurons.
Macrophage migration inhibitory factor acts via its intrinsic thiol-protein oxidoreductase activity to negatively regulate the neuronal chronotropic actions of angiotensin II in normotensive rat neurons. Because the chronotropic action of angiotensin II is potentiated in spontaneously hypertensive rat neurons, we investigated whether this negative regulatory mechanism is absent in these rats. A...
