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...

Lactoferrin is an iron-binding protein present in large quantities in colostrum and in breast milk, in external secretions and in polymorphonuclear leukocytes. Lactoferrin's main function is non-immune protection. Among several protective activities shown by lactoferrin, those displayed by orally administered lactoferrin are: (i) antimicrobial activity, which has been presumed due to iron depri...

Lactoferrin (Lf) was discovered in 1939 as “red protein from milk whey”. Bovine lactoferrin (bLf) gene is located on Bos taurus autosome, long arm of chromosome no.22 (BTA 22q24) in cattle. Its size varies from 23-35kbp among different species. The lactoferrin gene consists of 17 exons and 16 introns ranging from 82bp (exon-1) to 225bp (exon-17). The presence of multiple regulatory elements wit...

We compared the susceptibility to viral infection of splenocytes, isolated from young versus old CBA mice, and evaluated the antiviral actions of lactoferrin in splenocytes infected with Encephalomyocarditis virus (EMCV). Recombinant mouse lactoferrin (rmLF) and bovine lactoferrin (bLF) were used. There were no differences in the susceptibility to EMCV infection in the studied age categories. B...

This study was done primarily to determine whether the previously observed specificity of the meningococcal transferrin and lactoferrin receptors for human proteins was maintained in vivo during meningococcal infection in mice. Preliminary experiments evaluating the choice of host strain, the age and sex of mice, and the growth conditions of the meningococci indicated that 45-day-old female Swi...

The aim of this experimental study was to evaluate the effect of bovine lactoferrin (bLF)-loaded gelatin microspheres (GM) used in combination with anorganic bovine bone on bone regeneration in surgically created bone defects around tooth implants. Twenty-four uniform bone defects were created in the frontal bone via an extraoral approach in 12 domestic pigs. Twenty-four implants were placed at...

INTRODUCTION Under conditions of shock, bacteria and endotoxins in the intestines can traverse the mucosal barrier by translocation and enter the blood and lymphatic system. Immunoglobulins and lactoferrin have been reported to neutralize endotoxins and bacteria. We studied the essential therapeutic factors of colostrum products in an animal experiment. METHOD We simulated endotoxaemia by per...

Enterohemorrhagic Escherichia coli (EHEC) strains, of which E. coli O157:H7 is the best-studied serotype, are an important group of foodborne pathogens causing severe illness in humans worldwide. The main reservoirs for EHEC are ruminants, mostly cattle, which harbor the bacteria in their intestinal tracts without showing clinical symptoms. In this study, we used bovine lactoferrin, a natural o...

Lactoferrin (Lf), an iron-binding protein from the transferrin family has been reported to have numerous functions. Even though Lf was first isolated from milk, it is also found in most exocrine secretions and in the secondary granules of neutrophils. Antimicrobial and anti-inflammatory activity reports on lactoferrin identified its significance in host defense against infection and extreme inf...
