Campylobacter jejuni NCTC 11168 was capable of growth to levels comparable with FeSO4 in defined iron-limited medium (minimal essential medium alpha [MEMalpha]) containing ferrilactoferrin, ferritransferrin, or ferri-ovotransferrin. Iron was internalized in a contact-dependent manner, with 94% of cell-associated radioactivity from either 55Fe-loaded transferrin or lactoferrin associated with th...

The effect of the innovative product Neolactoferrin, a natural combination of recombinant human lactoferrin (90%) and goat lactoferrin (10%) isolated from the milk of transgenic goats carrying the full-length human lactoferrin gene, on human immune system cells was studied. Neolactoferrin enhanced the production of IL-1β. Neolactoferrin saturated with iron ions increased the synthesis of pro-in...

background: lactoferrin (lf) is a glycoprotein, a member of the transferrin family.from ten known mechanisms of anti-cancer chemoperotecive compounds, lf alone, has six of these functions and inhibits cancer. in this study, the effect of lactoferrin purified from bovine colostrum was studied as an anti-cancer agent on esophageal cancer cell line. materials and methods: bovine colostrum were col...

Lactoferrin is a 703-amino acid glycoprotein originally isolated from milk. Plasma lactoferrin is predominantly neutrophil derived but indications are that it may also be produced by other cells. Lactoferrin in body fluids is found in the iron-free form, the monoferric form and in the diferric form. Three isoforms of lactoferrin have been isolated, ie two with RNase activity (lactoferrin-beta a...

Background: Hyperlipidemia is a condition that characterized as an increase in total cholesterol and triglyceride levels the blood. Lactoferrin protein can serve antioxidant. This study aims to determine whether lactoferrin reduce levels.

Eosinophils are strongly implicated in the pathogenesis of asthma, particularly in damage to the airway epithelial lining. We examined the potential for lactoferrin, a multifunctional glycoprotein present in the airway surface liquid, to activate eosinophils. Incubating eosinophils in tissue culture wells pretreated with 1-100 microg/ml human lactoferrin stimulated concentration-dependent super...

Monocytes and macrophages have receptors for the iron-binding protein lactoferrin. Lactoferrin acts as a potent inhibitor of granulocyte-macrophage colony stimulating factor production when it binds to these cells. Using a rosette assay and immunofluorescence, we have shown that cultured leukemia cells, including the human erythroid leukemia cell line K562, also have lactoferrin binding sites. ...

background lactoferrin is a multipurpose protein of the transferrin domestic. it is a spherical glycoprotein with a molecular weight of about 80 kda which is widely found in secretory discharges, such as milk, saliva, tear, and nasal secretions. lactoferrin is also found in secondary granules of polymorphonuclear leukocytes (pmn) and is released by some acinar cells. it also shows antibacterial...

Background: Lactoferrin is a glycoprotein with a molecular weight of 80 kDa, as a member of the transferring family. In recent investigations the important biological properties such as anti microbial, antiviral and anticancer activity of lactoferrin were studied. In the present study, the effect of antitumor induced by lactoferin was evaluated on stomach cancer cell AGS. Materials and Methods...

This study analyzed the association between single nucleotide polymorphism (A/C) in position -28 located in the TATA box of LTF gene and the lactoferrin concentration in bovine milk secreted by healthy and infected udders. Out of 241, 69 cows were selected into the experimental group and were divided into 3 groups according to mean value of somatic cell count (SCC): I < 180,000 cells/mL, II: 18...
