Iron erythropoiesis
WebFeb 12, 2015 · Considering that hepatic TfR2 controls systemic iron traffic, these findings provide a molecular link between iron metabolism and erythropoiesis. Erythroid cells consume the vast majority (70-80%) of body iron for synthesis of heme, the oxygen-binding cofactor of hemoglobin (Hb). Under physiological conditions, plasma iron is captured by ... WebMar 11, 2024 · Erythropoietin (EPO) is a glycoprotein hormone, naturally produced by the peritubular cells of the kidney, that stimulates red blood cell production. Renal cortex peritubular cells produce most EPO in the human body. PO2 directly regulates EPO production. The lower the pO2, the greater the production of EPO.

WebErythropoiesis is a tightly controlled, iron-dependent process that begins with hematopoietic stem cells and maturates to red blood cells. HO-1 is expressed in hematopoietic stem/progenitor cells, hematopoietic niche cells, erythroblasts, and especially erythroblastic island and phagocytic macrophages. HO-1 functions importantly in the entire ... WebAug 24, 2024 · This results in less circulating iron available for erythropoiesis (represented by low TSAT) and increased storage iron (represented by high ferritin level). IV iron is variably effective in overcoming this “reticuloendothelial iron blockade” that leads to ESA hyporesponsiveness.
WebErythropoiesis is impaired when serum iron falls to < 50 mcg/dL (< 9 micromol/L) and transferrin saturation to < 16%. The serum transferrin receptor level rises ( > 8.5 mg/L). … WebThe erythropoiesis/hepcidin crosstalk The iron needs of erythropoiesis are primarily sustained by macrophages that in adults recycle iron (20–25 mg/day) derived from senescent erythrocyte breakdown. Transferrin provides iron to the TFR1 endosomal cycle and its percent saturation inversely reflects the iron consumed in erythro-poiesis.
