Erythropoietin (EPO) is an endogenous regulator of erythropoiesis and is given exogenously as a replacement therapy for selected red blood cell disorders. In the past years, EPO has been emerging as a multifunctional, cytoprotective cytokine with anti-apoptotic, anti-inflammatory, and immunomodulatory properties. We aimed to evaluate the cytoprotective effect of rhEPO (recombinant human EPO) treatment on a rat model of multiorgan dysfunction induced by thermal injury. rhEPO was administered at 1000 U/kg (i.v.) 5 min prior to induction of injury and significantly reduced multiorgan dysfunction markers (liver, kidney, lung, serum cytokine levels). In the lung, rhEPO reduced: histological signs of tissue injury, inflammatory/injury markers on the bronchoalveolar fluid, neutrophil chemotaxis/infiltration, GSK-3β activation, and apoptosis. Our study showed that erythropoietin has the potential to exhibit …
