Stealthy microbes: How Neisseria gonorrhoeae hijacks bulwarked iron during infection

open access: yesFrontiers in Cellular and Infection Microbiology, 2022
Transition metals are essential for metalloprotein function among all domains of life. Humans utilize nutritional immunity to limit bacterial infections, employing metalloproteins such as hemoglobin, transferrin, and lactoferrin across a variety of ...

Structure of the Human Transferrin Receptor-Transferrin Complex [PDF]

open access: yesCell, 2004
Iron, insoluble as free Fe(3+) and toxic as free Fe(2+), is distributed through the body as Fe(3+) bound to transferrin (Tf) for delivery to cells by endocytosis of its complex with transferrin receptor (TfR). Although much is understood of the transferrin endocytotic cycle, little has been uncovered of the molecular details underlying the formation of

Paraoxonases (PON) 1, 2, and 3 Polymorphisms and PON-1 Activities in Patients with Sickle Cell Disease

open access: yesAntioxidants, 2019
(1) Background: Oxidative stress, chronic inflammation, vasoocclusion, and free iron are all features present in sickle cell disease. Paraoxonases (PON) are a family (PON-1, PON-2, PON-3) of antioxidant enzymes with anti-inflammatory action.

Key players in the regulation of iron homeostasis at the host-pathogen interface

open access: yesFrontiers in Immunology, 2023
Iron plays a crucial role in the biochemistry and development of nearly all living organisms. Iron starvation of pathogens during infection is a striking feature utilized by a host to quell infection.

DISTRIBUTION OF TRANSFERRIN AND TRANSFERRIN RECEPTORS IN THE RABBIT PLACENTA [PDF]

open access: yesQuarterly Journal of Experimental Physiology, 1983
The quantity and distribution of transferrin and transferrin‐binding sites in the placenta were investigated in rabbits on the 28th‐29th days of pregnancy. The animals were injected intravenously with a mixture of 59Fe‐125I‐labelled rabbit diferric transferrin and 131I‐labelled rabbit albumin.

DNA-binding transferrin conjugates as functional gene-delivery agents: synthesis by linkage of polylysine or ethidium homodimer to the transferrin carbohydrate moiety [PDF]

open access: yes, 1991
We have previously demonstrated that transferrin-polycation conjugates are efficient carrier molecules for the introduction of genes into eucariotic cells.

Localization of Transferrin and Transferrin Receptors in Rat Testes [PDF]

open access: yesBiology of Reproduction, 1984
One of the major proteins secreted by rat Sertoli cells in culture is a transferrin-like protein (Skinner and Griswold, 1980). The purpose of this study was to quantitate the amount of testicular transferrin in fluids isolated from the testis by the use of a radioimmunoassay and to determine the location of transferrin and transferrin receptors in the ...

Abnormal Serum Iron-Status Indicator Changes in Amyotrophic Lateral Sclerosis (ALS) Patients: A Meta-Analysis

open access: yesFrontiers in Neurology, 2020
Background: In recent years, the role of iron metabolism in amyotrophic lateral sclerosis (ALS) attracts more and more attention, and some studies have focused on the link between abnormal serum iron indicators and ALS.

Indices of metal proteins (transferrin, ceruloplasmin) in overweight and obese children [PDF]

open access: yesArchives of the Balkan Medical Union, 2019
Introduction. A progressive increase of obesity prevalence, both among adults and children, is observed in many countries. Today, obesity is seen as a chronic systemic inflammation with low activity. Currently, new data are available about the biological

Biochemical, Biophysical, and Cellular Investigations of the Interactions of Transferrin Receptor with Transferrin and the Hereditary Hemochromatosis Protein, HFE [PDF]

open access: yes, 2004
Hereditary hemochromatosis (HH) is a prevalent genetic disorder that results in the daily excess absorption of dietary iron. If untreated this disease leads to systemic organ failure and death. HH is caused by mutations to the gene coding for a protein
