Transferrin receptor 2 (TFR2) is a transmembrane glycoprotein expressed in the liver and in the erythroid compartment, mutated in a form of hereditary hemochromatosis. Hepatic TFR2, together with HFE, activates the transcription of the iron-regulator hepcidin, while erythroid TFR2 is a member of the erythropoietin receptor complex. The TMPRSS6 gene,(More)
The Transferrin Receptor 2 (Tfr2) modulates systemic iron metabolism through the regulation of iron regulator Hepcidin (Hepc) and Tfr2 inactivation causes systemic iron overload. Based on data demonstrating Tfr2 expression in brain, we analysed Tfr2-KO mice in order to examine the molecular, histological and behavioural consequences of Tfr2 silencing in(More)
Transferrin receptor 2 (Tfr2) is an iron-modulator transcribed in two isoforms, Tfr2α and Tfr2β. The latter is expressed in the heart. We obtained two mouse models with silencing of Tfr2β: one with a normal systemic iron amount (SIA), i.e., Tfr2-KI, and the other, i.e., LCKO-KI, with high SIA due to hepatic Tfr2α silencing. We aimed to assess whether Tfr2β(More)
Type 3 haemochromatosis (HFE3) is a rare genetic iron overload disease which ultimately lead to compromised organs functioning. HFE3 is caused by mutations in transferrin receptor 2 (TFR2) gene that codes for two main isoforms (Tfr2α and Tfr2β). Tfr2α is one of the hepatic regulators of iron inhibitor hepcidin. Tfr2β is an intracellular isoform of the(More)
