Semiquantitative analysis of lactoferrin deficiency in neutrophil polymorphonuclear leucocytes in various haematological and non-haematological disease was carried out by scoring polymorphonuclear leucocytes stained for lactoferrin by the immunoperoxidase method. The staining patterns for lactoferrin were classified into four types (0-III) based on the intensity of reaction, and the sum of the ...

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...

The purposes of this study were to investigate the levels of lactoferrin in 180 normal and 132 mastitic camel milk samples and to elucidate the effect of age, lactation stage, presence of pathogens, and somatic cell counts (SCC) on the concentration of lactoferrin in camel milk using radial immunodiffusion test. The mean log concentration of lactoferrin from mastitic camels (3.8 ± 0.67) was sig...

Lactoferrin is a multifunctional glycoprotein found in the milk of most mammals. In addition to its well-known role of binding iron, lactoferrin carries many important biological functions, including the promotion of cell proliferation and differentiation, and as an anti-bacterial, anti-viral, and anti-parasitic protein. These functions differ among lactoferrin homologs in mammals. Although con...

Streptococcus dysgalactiae ssp. dysgalactiae is an important causative agent of bovine mastitis worldwide. Lactoferrin is an innate immune protein that is associated with many functions including immunomodulatory, antiproliferative, and antimicrobial properties. This study aimed to investigate the interactions between lactoferrin and a clinical bovine mastitis isolate, Strep. dysgalactiae ssp. ...

The existence of lactoferrin was first reported by S0rensen and S0rensen,' who observed a red protein fraction in human milk. The protein was first isolated by Groves2 from bovine and by Johansson3 from human milk, and subsequent studies showed that this protein (which has been variously called red milk protein, ekkrinosiderophilin, and lactotransferrin) is strikingly similar in many respects t...

Bovine herpesvirus 1 (BoHV-1) is widely distributed among cattle populations and has been associated with cells, fluids, and tissues collected from donor animals for use in reproductive technologies. The purpose of this study was to determine if lactoferrin would inhibit BoHV-1 in cell culture and to evaluate if embryos could develop normally when cultured in vitro with lactoferrin. In Experime...

With the successful clinical trials, multifunctional glycoprotein bovine lactoferrin is gaining attention as a safe nutraceutical and biologic drug targeting cancer, chronic-inflammatory, viral and microbial diseases. Interestingly, recent findings that human lactoferrin oligomerizes under simulated physiological conditions signify the possible role of oligomerization in the multifunctional act...

Interleukin-8 (IL-8), a C-X-C chemokine bound to endothelium proteoglycans, initiates the activation and selective recruitment of leukocytes at inflammatory foci. We demonstrate that human lactoferrin, an antimicrobial lipopolysaccharide (LPS)-binding protein, decreases both IL-8 mRNA and protein expression induced by the complex Escherichia coli 055:B5 LPS/sCD14 in human umbilical vein endothe...

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...
