Current understanding of iron homeostasis
Iron is an essential trace element, but it is also toxic in excess, and thus mammals have developed elegant mechanisms for keeping both cellular and whole-body iron concentrations within the optimal physiologic range. In the diet, iron is either sequestered within heme or in various nonheme forms. Although the absorption of heme iron is poorly …

Bhana et al. ... can be considered an interesting model for the study of iron storage, with an irregular distribution of the metal. ... usefulness of the plasma ferritin concentration as a predictor ...
12.72 Iron Transport & Storage | Nutrition Flexbook
Once inside cells, the iron can be used for cellular purposes (cofactor for enzyme etc.) or it can be stored in the iron storage proteins ferritin or hemosiderin. Ferritin is the primary iron storage protein, but at higher concentrations, iron is also stored in hemosiderin 2.
An update on iron physiology
The remaining body iron is stored in the liver (200 mg), macrophages of the reticuloendothelial system (RES; 500 mg), and bone marrow (150 mg). In premenopausal women, total body iron (especially the stored fraction, 250-300 mg) is lower than in men. The normal diet contains 15-20 mg of iron, and the body absorbs 1-2 mg/d …
The ferritins: molecular properties, iron storage function and …
The iron storage protein, ferritin, plays a key role in iron metabolism. Its ability to sequester the element gives ferritin the dual functions of iron detoxification and iron reserve. The importance of these functions is emphasised by ferritin''s ubiquitous distribution among living species. Ferritin''s three-dimensional structure is highly ...
Serum ferritin iron, a new test, measures human body iron stores ...
Serum ferritin iron is a simple, direct measure of iron stores that we propose, in …
Hepatic Iron Concentration in Hereditary Hemochromatosis Does …
The phle botomy requirement for treatment of HH cannot be accurately predicted from the initial HIC or serum ferritin level, and accurate prediction of individual phlebotomy requirements based on the H IC or serumferritin concentration at the time of diagnosis was not possible. Objective:Biochemical measurement of the hepatic iron …

Estimation of Body Iron Stores | SpringerLink
2.3.3.3 Serum Ferritin and Iron Deficiency. A threshold of 15 μg/L, below which iron stores are absent, was derived by measuring serum ferritin concentrations in patients with iron-deficiency anemia – defined as microcytic anemia, with either an absence of stainable iron in the bone marrow or a subsequent response to therapeutic iron …
Ferritin – from iron, through inflammation and autoimmunity, to …
1. Introduction. Initially addressed as a surrogate marker for the status of iron storage in the human body, ferritin which is derived from the Latin word "ferratus" for iron-bearing, was considered to be merely related to iron and iron level in the human body [1].Low ferritin levels indicated decreased body iron levels whereas high levels indicated …

Iron metabolism and management: focus on chronic kidney disease
In contrast, functional iron deficiency is a state in which total body iron stores are sufficient but iron is not effectively mobilized from storage; this can occur under conditions of chronic inflammation or when erythropoiesis is stimulated to a large, supraphysiologic degree, such as during treatment with ESAs. 26 A hallmark of functional ...
Serum or plasma ferritin concentration as an index of iron …
Ferritin can be measured in the serum or plasma, as well as in the erythrocyte. Ferritin is an iron storage protein, chiefly found in the liver, and comprises two isoforms of poli peptidic chains (L‐light, and H‐heavy). ... ferritin concentrations are thought to reflect body iron stores . It is, therefore, important to determine if serum or ...
Does iron concentration in a liver needle biopsy accurately reflect ...
The dangerous effects of iron excess can be managed by administration of chelators capable of removing iron from transferrin, ferritin, and other iron stores (5)(6)(7). Determination of the hepatic iron concentration (HIC) is one of the most valid procedures in assessing real body iron burden (8)(9)(10), which is important for adjusting each ...
