conclusions further studies on the role of hepcidin in pathogenesis of chc are needed to assess the potency of its use in antiviral treatment. results patients with chc had lower hepcidin mrna expression and more frequently iron deposits in hepatocytes than subjects with chb did. in chc group, hepcidin mrna expression was positively correlated with alanine aminotransferase activity and serum ir...

PURPOSE The body concentration of iron is regulated by a fine equilibrium between absorption and losses of iron. Iron can be absorbed from diet as inorganic iron or as heme. Hemopexin is an acute phase protein that limits iron access to microorganisms. Moreover, it is the plasma protein with the highest binding affinity for heme and thus it mediates heme-iron recycling. Considering its involvem...

Food-borne polyphenols have long contributed to human health via multifaceted mechanisms, while emerged studies especially those published in recent 10 years witnessed the close relevance between bioactivity of with iron homeostasis. Polyphenols are involved various physiological processes and manifest multidirectional regulative effects. The diversiform polyphenols–iron interactions extended c...

Iron is an essential trace element subject to tight regulation to ensure adequate running of biological processes. In sub-Saharan Africa where hemoglobinopathies are common, iron homeostasis is likely to be impaired by these conditions. Here, we assessed and compared key serum proteins associated with iron metabolism between sub-Saharan African children with sickle cell disease (SCD) and their ...

Due to its multiple roles for the proliferation and pathogenicity of many microbes on the one hand and via modulation of immune effector functions on the other hand the control over iron homeostasis is thought to play a decisive role in the course of infections. Diversion of cellular iron traffic is considered as an important defense mechanism of macrophages to reduce metal availability for int...

PURPOSE Iron accumulation with age in the retinal pigment epithelium (RPE) may be one important source of oxidative stress that contributes to age-related macular degeneration (AMD). Young and old rodent RPE/choroid were compared to assess iron homeostasis during normal aging and the effects of increased iron on the functions of retinal pigment epithelial cells. METHODS The iron level, mRNA e...

Erythroid function and development is intimately linked to macrophages. The primary function of erythrocytes is oxygen delivery, which is mediated by iron-containing hemoglobin. The major source of this iron is a recycling pathway where macrophages scavenge old and damaged erythrocytes to release iron contained within the heme moiety. Macrophages also promote erythropoiesis by providing a suppo...
