Erythropoietin (epoetin) as a protective factor for the brain

Abstract

Erythropoietin (EPO) has been viewed traditionally as a hematopoietic cytokine. Emerging evidence now exists supporting a physiologic role for EPO within the nervous system. EPO is expressed in the developing central nervous system and is capable of regulating the production of neuronal progenitor cells. There are numerous preclinical studies demonstrating a neuroprotective potential for EPO in a variety of disorders of both the central and peripheral nervous systems. A small pilot study in patients with acute ischemic stroke has recently been completed and the results are encouraging. Its mechanism of action is multifactorial but probably related to its ability to act as an antiapoptotic agent. Its widespread use clinically for the treatment of anemias has given us the experience and knowledge of its safety and pharmacokinetics. EPO is thus an ideal compound to study for the potential treatment of a variety of neurologic disorders.
