It has been demonstrated that under iron-restricted conditions Bordetella pertussis can take up iron from human transferrin within 30 min of exposure. B. pertussis utilizes two mechanisms for acquiring iron from human transferrin, a direct contact method and a siderophore mediated system. Both systems are shown to result in bacterial internalization of iron from transferrin. However, direct con...

BACKGROUND Transferrin saturation reference intervals specific for age and sex have not been previously reported for the pediatric population. The reference values for transferrin saturation have been previously reported to be lower in children compared to adults, caused by a combination of low serum iron and high serum transferrin levels in children, warranting specific reference intervals. He...

Encapsulation of iron oxide and gold nanoparticles into the bilayer structure transferrin-modified niosomes enables greatly enhanced contamination-free SERS-signals in vitro as well a dual-targeting functionality towards cancer cells.

Serum contains 1-transferrin, and CSF contains 1 and 2 transferrins. The 2-transferrin in CSF is desialylated because of the presence of neuraminidase in the central nervous system. Hence, 2-transferrin is used as a marker of CSF leakage (1 ). Because 1-transferrin was present in serum but absent in drainage fluid, additional neuraminidase activity was suspected. This suspicion was supported by...

Fe-salicylaldehyde isonicotinoylhydrazone (SIH), which can donate iron to reticulocytes without transferrin as a mediator, has been utilized to test the hypothesis that the rate of iron uptake from transferrin limits the rate of heme synthesis in erythroid cells. Reticulocytes take up 59Fe from [59Fe]SIH and incorporate it into heme to a much greater extent than from saturating concentrations o...

Iron is bound to transferrin in the plasma. A specific receptor on the cell surface binds transferrin and internalizes transferrin and the iron in clathrin-coated pits. These invaginate to form vesicles which release iron to the cytoplasm. Inorganic iron can be transported by an alternative pathway from iron citrate, utilizing a cell surface integrin and a cytoplasmic protein mobilferrin. This ...

New strategies to treat antibiotic-resistant infections are urgently needed. We serendipitously discovered that stem cell conditioned media possessed broad antimicrobial properties. Biochemical, functional, and genetic assays confirmed that the antimicrobial effect was mediated by supra-physiological concentrations of transferrin. Human transferrin inhibited growth of gram-positive (Staphylococ...

One of the major proteins secreted by Sertoli cells (Band 3) has a molecular weight on sodium dodecyl sulfate-polyacrylamide gels which corresponds to rat serum transferrin. The preparation of Sertoli cell-secreted proteins contains an iron-binding protein with electrophoretic properties on native polyacrylamide gels similar to serum transferrin. Antibodies against Sertoli cell-secreted protein...

BACKGROUND The most frequent i.v. iron preparations used for haemodialysis patients are iron dextran, iron gluconate and iron saccharate. Possible side effects include anaphylactic reactions due to preformed antibodies to dextran or vascular reactions due to unbound iron during treatment with iron gluconate or iron saccharate. METHODS Four dosage regimens of i.v. iron saccharate therapy were ...
