Erythropoietin (EPO) is both hematopoietic and tissue protective, putatively through interaction with different receptors. We generated receptor subtype-selective ligands allowing the separation of EPO's bioactivities at cellular level in animals. Carbamylated EPO (CEPO) or certain mutants did not bind to classical (EPOR) show any activity human cell signaling assays upon chronic dosing animal species. Nevertheless, CEPO various nonhematopoietic were cytoprotective vitro conferred...

The cytokine erythropoietin (EPO) possesses potent neuroprotective activity against a variety of potential brain injuries, including transient ischemia and reperfusion. It is currently unknown whether EPO will also ameliorate spinal cord injury. Immunocytochemistry performed using human sections showed abundant receptor immunoreactivity capillaries, especially in white matter, motor neurons within the ventral horn. We used global model rabbits to test exogenous can cross blood-spinal barrier...

Erythropoietin (EPO) is a tissue-protective cytokine preventing vascular spasm, apoptosis, and inflammatory responses. Although best known for its role in hematopoietic lineages, EPO also affects other tissues, including those of the nervous system. Enthusiasm recombinant human erythropoietin (rhEPO) as potential neuroprotective therapeutic must be tempered, however, by knowledge it enlarges circulating red cell mass increases platelet aggregability. Here we examined whether erythropoietic...

Erythropoietin (EPO) functions as a tissue-protective cytokine in addition to its crucial hormonal role red cell production. In the brain, for example, EPO and receptor are locally produced, modulated by metabolic stressors, provide neuroprotective antiinflammatory functions. We have previously shown that recombinant human (rhEPO) administered within systemic circulation enters brain is neuroprotective. At present, it unknown whether rhEPO can also improve recovery after traumatic injury of...

Erythropoietin (EPO), a member of the type 1 cytokine superfamily, plays critical hormonal role regulating erythrocyte production as well paracrine/autocrine in which locally produced EPO protects wide variety tissues from diverse injuries. Significantly, these functions are mediated by distinct receptors: hematopoiesis via receptor homodimer and tissue protection heterocomplex composed CD131, β common receptor. In present work, we have delimited tissue-protective domains within to short...

Erythropoietin (EPO) is a neuroprotective cytokine in models of ischemic and nervous system injury, where it reduces neuronal apoptosis inflammatory cytokines increases neurogenesis angiogenesis. EPO also improves cognition healthy volunteers schizophrenic patients. We studied the effect administration on gene-expression profile cortex rats after cerebral ischemia at early time points (2 6 h). treatment up-regulated genes already increased by ischemia.

Previous studies have shown that erythropoietin (EPO) has protective effects against ischemia/reperfusion (I/R) injury in several tissues. The aim of this study was to determine whether EPO could prevent intestinal tissue induced by I/R. Wistar rats were subjected ischemia (30 min) and reperfusion (60 min). A single dose (5000 U/kg) administered intraperitoneally at two different time points: either five minutes before the onset or reperfusion. At end period, jejunum removed for...

Object Spinal cord injury (SCI) is a devastating clinical syndrome for which no truly efficacious therapy has yet been identified. In preclinical studies, erythropoietin (EPO) and its nonerythropoietic derivatives asialoEPO carbamylated EPO have markedly improved functional outcome when administered after compressive SCI. However, an optimum treatment paradigm currently unknown. Because the uninjured spinal expresses high density of receptor (EPOR) in basal state, signaling through these...

Erythropoietin (EPO) is a type I cytokine that utilizes different receptor isoforms either to maintain hematopoiesis or protect against injuries arise from widely diverse etiologies. EPO also facilitates healing by reducing inflammation and mobilizing endothelial progenitor cells participate in restorative neoangiogenesis, but it unclear which isoform responsible for whether this use varies according the of wound.

Gamma knife radiosurgery is an attractive noninvasive treatment of brain tumors and vascular malformations that minimizes collateral tissue damage. However, exposure normal to even low-dose radiation triggers a cascade acute chronic injury potentially significant morbidity mortality. Because many irradiated patients now survive for years, identifying methods prevent radiotherapy-induced damage major focus current research.
