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...
Lactoferrin is a glycoprotein with molecular weight 80 kDa iron-binding bond, which is composed of 690 amino acids. In most mammalian body fluids such as sweat, semen, tears, and saliva and milk neutrophil granules there. bovine lactoferrin gene be associated with susceptibility/resistance to mastitis and even with some economically important production traits. This study was carried out to det...
We describe a rapid, precise, and sensitive radiometric assay for human lactoferrin. In this typical "sandwich"-type assay, anti-human lactoferrin is adsorbed onto a polystyrene sphere and bound lactoferrin is detected by the subsequent binding of 125I-labeled anti-human lactoferrin. The assay is accurate for lactoferrin concentrations of 5 to 1500 micrograms/L and takes about 2.5 h to complete...
Lactoferrin is an iron-binding glycoprotein that belongs to the transferrin family. It is present in breast milk, in epithelial secretions, and in the secondary granules of neutrophils. In healthy subjects lactoferrin circulates at concentrations of 2-7 x 10(-6) g/ml. Lactoferrin is a pleiotropic factor with potent antimicrobial and immunomodulatory activities. Recently, we have shown that lact...
Lactoferrin is a major component of breast milk protein, constituting 10-15% of the total content. Each molecule of lactoferrin is capable of binding two atoms of iron and it has been proposed that lactoferrin is involved in iron absorption in the newborn infant. It is known that iron status of exclusively breast-fed infants usually is satisfactory to 6-9 months of age, in spite of a low iron c...
