The proinflammatory cytokine MIF (macrophage migration inhibitory factor) is involved in physiological and pathological processes in pregnancy. MIF maternal serum levels are increased in preeclampsia (PE). We hypothesize that pregnancy tissues are the source of MIF overexpression in PE. MIF protein was studied in maternal sera, placental tissues, fetal membranes, and umbilical cord of 8 control...

Macrophage migration inhibitory factor (MIF) has been shown to play a pathogenic role in kidney disease. This article will review the current understanding of the expression of MIF and its functional role in immune-mediated renal injury in both human and animal models of kidney disease. Upregulation of MIF is found in both human and experimental kidney disease including renal allograft rejectio...

Macrophage migration inhibitory factor (MIF) is closely associated with tumorigenesis. The present study aimed to investigate the effects of MIF on the proliferation, migration and colony formation of oral squamous cell carcinoma (OSCC), and to quantify the protein expression levels of MIF in OSCC tissue samples. Firstly, small interfering (si) RNA was used to knock down the gene expression of ...

For over 25 years, the cytokine known as macrophage migration inhibitory factor (MIF) has been considered to be a product of activated T lymphocytes. We recently identified the murine homolog of human MIF as a protein secreted by the pituitary in response to endotoxin administration. In the course of these studies, we also detected MIF in acute sera obtained from endotoxin-treated, T cell-defic...

Tumor-derived growth factors and cytokines stimulate neoangiogenesis from surrounding capillaries to support tumor growth. Recent studies have revealed that macrophage migration inhibitory factor (MIF) expression is increased in lung cancer, particularly non-small cell lung carcinomas (NSCLC). Because MIF has important autocrine effects on normal and transformed cells, we investigated whether a...

BACKGROUND We have previously reported that macrophage migration-inhibitory factor (MIF) is associated with an unfavorable prognosis in hypopharyngeal carcinoma. Here, we quantified MIF expression in oral cavity carcinomas and looked for possible correlations with clinical outcome. MATERIALS AND METHODS MIF expression was assessed by immunohistochemistry in a cohort of 154 oral cavity carcino...

Macrophage migration inhibitory factor (MIF) is an important proinflammatory cytokine involved in regulation of macrophage function. In addition, MIF may also play a role in murine and human reproduction. Although both first trimester trophoblast and decidua express MIF, the regulation and functional significance of this cytokine during human placental development remains unclear. We assessed M...

Macrophage infiltration is a critical determinant of high-fat diet induced adipose tissue inflammation and insulin resistance. The precise mechanisms underpinning the initiation of macrophage recruitment and activation are unclear. Macrophage migration inhibitory factor (MIF), a pro-inflammatory cytokine, displays chemokine-like properties. Circulating MIF levels are elevated during obesity how...

Background: Macrophage migration inhibitory factor (MIF) is a key pro-inflammatory cytokine that is secreted by active macrophages accumulated in ectopic tissue of endometriosis. It involves in pathophysiological events of endometriosis such as angiogenesis, cell proliferation and it can stimulate the synthesis of PGE2 that are necessary for survival and establishment of ectopic endometriosis t...

Macrophage migration inhibitory factor (MIF) is a proinflammatory cytokine known to activate macrophages and T cells. In this study, we demonstrate that recombinant MIF delays apoptosis of neutrophils in vitro. MIF action is dose and time dependent as well as specific since it was abolished with a neutralizing anti-MIF antibody. MIF, like G-CSF, delayed cleavage of the proapoptotic members of t...
