Glioma, as a primary tumor of central nervous system, is the main cause of death in patients with brain cancer. Therefore, development of an efficient strategy for treatment of glioma is worthy. The aim of the current study was to develop a SRL peptide-coated dendrimer as a novel dual gene delivery system for targeting the LRP receptor, an up-regulated gene in both BBB and glioma cells. To perf...

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...

Lactoferrin is an iron-binding glycoprotein, which is present in most biological fluids with particularly high levels in colostrum and in mammalian milk. Bovine lactoferrin is more than 70% homologous with human lactoferrin. Most of the clinical trials have used bovine lactoferrin for supplementation. This review summarizes the recent advances in explaining the mechanisms, which are responsible...

Hepatitis C virus (HCV) has two envelope proteins, E1 and E2, which form a heterooligomer. During dissection of interacting regions of HCV E1 and E2, we found the presence of an interfering compound or compounds in skim milk. Here we report that human as well as bovine lactoferrin, a multifunctional immunomodulator, binds two HCV envelope proteins. As determined by far-Western blotting, the bac...

OBJECTIVES Lactoferrin is an iron-binding protein that is released from activated neutrophils at sites of inflammation and has anti-microbial as well as anti-inflammatory properties. This study set out to determine whether lactoferrin can delay neutrophil apoptosis and could act as a survival factor for neutrophils in SF. METHODS Human peripheral blood and SF neutrophils were incubated with i...

The acquisition of lactoferrin and transferrin by live Treponema pallidum organisms was examined. Saturation binding kinetics were obtained for virulent treponemes with increasing amounts of radioiodinated lactoferrin but not with transferrin. Furthermore, lactoferrin bound up to 100 times more effectively than transferrin. Only unlabelled lactoferrin stoichiometrically completed with iodinated...

A sandwich e.l.i.s.a. method was developed to examine the distribution of lactoferrin in mouse reproductive tract. The lactoferrin concentration was found to be much higher in oviduct, uterus, vagina, vas deferens or epididymis than in serum, but the concentration in ovary, testis, seminal vesicle, prostate or coagulating gland was comparable with that in serum. The existence of lactoferrin in ...

1. Lactoferrin and aminopeptidase M-modified lactoferrin (APM-lactoferrin; which lacks its 14 N-terminal amino acids) inhibit the liver uptake of lipoprotein remnant. In the present study, the role of proteoglycans in the initial interaction of beta-migrating very-low-density lipoprotein (beta-VLDL), native and APM-lactoferrin with isolated rat parenchymal liver cells was investigated. Treatmen...

In this study, cDNA encoding the Camelus dromedarius lactoferrin (cLf) was isolated from mammary gland by reverse transcription polymerase chain reaction and cloned to the pART27 expression vector. Its predicted amino acid sequence was analyzed and compared with lactoferrin of other mammalian species. Secondary and tertiary structures were predicted and modeled by online tools. Then cLf cDNA wa...
