EPO And EPO-Receptor System As Potential Actionable Mechanism To Protection of Brain And Heart In Refractory Epilepsy And SUDEP.

EPO And EPO-Receptor System As Potential Actionable Mechanism To Protection of Brain And Heart In Refractory Epilepsy And SUDEP. Curr Pharm Des. 2020 Feb 18;: Authors: Auzmendi J, Pûchulu MB, Garcia Rodriguez JC, Balaszczuk AM, Lazarowski A, Merelli A Abstract The most important activity of erythropoietin (EPO) is the regulation of erythrocyte production by activation of the erythropoietin receptor (EPO-R), which triggers the activation of antiapoptotic and proliferative responses of erythroid progenitor cells. Additionally, to erythropoietic EPO activity, an antiapoptotic effect has been described in a wide spectrum of tissues. EPO low levels are found in the central nervous system (CNS), while EPO-R is expressed in most CNS cell types. In spite of EPO-R high levels expressed during hypoxic-ischemic brain, insufficient production of endogenous cerebral EPO could be the cause of determined circuit alterations that lead to the loss of specific neuronal populations. In the heart, high EPO-R expression in cardiac progenitor cells appears to contribute to myocardial regeneration under EPO stimulation. Several lines of evidence have linked EPO to an antiapoptotic role in CNS and in heart tissue. In this review, we resume an antiapoptotic role of EPO/EPO-R system in both brain and heart under hypoxic conditions, such as epilepsy and sudden death (SUDEP). Additionally, their protective effects could be a new field of research and a novel t...
