The involvement of erythrocyte metabolism in organismal homeostasis in health and disease

Abstract

Historically, study of erythrocyte homeostasis has focussed on the survival of erythrocytes in the blood bank and, especially in pathological circumstances, on the mechanisms leading to accelerated aging and removal from the circulation. Recent proteomic and metabolomic data suggest that erythrocyte metabolism involves more than ATP production and transport of oxygen and carbondioxide; is subject to regulation; and is likely to reflect organismal metabolism. Also, it has become clear that systemic diseases affect erythrocyte homeostasis. The perspectives emerging from these data include new possibilities to manipulate erythrocyte function and survival in vivo, and thereby organismal homeostasis.
