WebJan 9, 2024 · While the mechanisms of iron transport across the physiological barriers at the gut and placenta have been intensively studied for decades, the detailed mechanisms of brain iron transport and regulation are still not fully elucidated [].These mechanisms involve trafficking of the Transferrin receptor (TfR) and its natural ligand, iron-binding … WebFeb 13, 2024 · our data, brain iron status can exert control of iron transport across the endothelial cells that constitute the BBB. These data address a number of pertinent questions such as how brain iron uptake is regulated at the regional level, the source of iron delivery to the brain, and the clinical strategies for attempting to treat brain iron ...
WebAs other organs, brain needs a fine regulation of iron metabolism for optimal cell functioning. A disorder of iron regulation would lead to local iron accumulation, producing free radicals, oxidative stress and cell death (“ferroptosis”). Plasmatic iron transport is provided by serum transferrin which is synthetized by hepatocytes. WebIn fact, fatigue, brain fog, and restless legs are often some of the first symptoms present in adults with iron-deficiency anemia. Other symptoms may include anxiety, depression, and irritability.
