Abstract

Both insufficient kidney production of erythropoietin and inflammation-mediated reduction of transferrin-bound iron are major factors in anemia of chronic kidney disease. Improved therapies for anemia in chronic kidney disease may involve modifying regulators of erythropoiesis and iron availability. Olivari etal. show in a mouse model of chronic kidney disease that transferrin receptor 2 in hepatocytes, where it is required for hepcidin production, and in erythroid cells, where it downregulates erythropoietin receptor activity, is a potential therapeutic target.
