abstract = {Iron is mostly devoted to the hemoglobinization of
erythrocytes for oxygen transport. However, emerging
evidence points to a broader role for the metal in
hematopoiesis, including the formation of the immune system.
Iron availability in mammalian cells is controlled by
iron-regulatory protein 1 (IRP1) and IRP2. We report that
global disruption of both IRP1 and IRP2 in adult mice
impairs neutrophil development and differentiation in the
bone marrow, yielding immature neutrophils with abnormally
high glycolytic and autophagic activity, resulting in
neutropenia. IRPs promote neutrophil differentiation in a
cell intrinsic manner by securing cellular iron supply
together with transcriptional control of neutropoiesis to
facilitate differentiation to fully mature neutrophils.
Unlike neutrophils, monocyte count was not affected by IRP
and iron deficiency, suggesting a lineage-specific effect of
iron on myeloid output. This study unveils the previously
unrecognized importance of IRPs and iron metabolism in the
formation of a major branch of the innate immune system.},
