Requirement for Α-l-fucose on the Macrophage Membrane Receptor for Mif

چکیده

alpha-L-fucose abolishes the activity of guinea pig migration inhibitory factor (MIF) on the macrophages. Other sugars such as alpha-D-glucose, beta-D-galactose, alpha-L-rhamnose, methyl-alpha-D-mannoside, and N-acetyl-beta-D-glucosamine had no effect. Theabolition of MIF activity by alpha-L-fucose was reversible. When macrophages were incubated with alpha-L-fucosidase, a glycosidase which splits terminal alpha-L-fucose from oligosaccharides, the macrophages no longer responded to MIF. On the other hand, MIF incubated with alpha-L-fucosidase was still active. These experiments strongly suggest that alpha-L-fucose comprises an essential part of a macrophage membrane receptor for MIF.

I-43: Expression Profile of Macrophage Migration Inhibitory Factor (MIF) Signaling Pathway as A Potentional Biomarker in Pathophysiology of Endometriosis

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...

Augmentation of macrophage complement receptor function in vitro. IV. The lymphokine that activates macrophage C3 receptors for phagocytosis binds to a fucose-bearing glycoprotein on the macrophage plasma membrane

Macrophage receptors for the third component of complement (C3) are normally immobilized and unable to diffuse within the cell's plasma membrane and, even though they promote avid particle binding, are unable to promote phagocytosis of C3-coated particles. We have previously identified a lymphokine that activates macrophage C3 receptors for phagocytosis and have found that it acts by freeing th...

O-28: Endometriosis Is Influenced by The Promoter Haplotype-Based Expression of Macrophage Migration Inhibitory Factor (MIF)

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...

Ribosomal protein S19 is a novel therapeutic agent in inflammatory kidney disease.

RPS19 (ribosomal protein S19), a component of the 40S small ribosomal subunit, has recently been identified to bind the pro-inflammatory cytokine macrophage MIF (migration inhibitory factor). In vitro experiments identify RPS19 as the first endogenous MIF inhibitor by blocking the binding of MIF to its receptor CD74 and MIF functions on monocyte adherence to endothelial cells. In the present st...
