Derivatives of erythropoietin that are tissue protective but not erythropoietic.

چکیده
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 the cellular level and in animals. Carbamylated EPO (CEPO) or certain EPO mutants did not bind to the classical EPO receptor (EPOR) and did not show any hematopoietic activity in human cell signaling assays or upon chronic dosing in different animal species. Nevertheless, CEPO and various nonhematopoietic mutants were cytoprotective in vitro and conferred neuroprotection against stroke, spinal cord compression, diabetic neuropathy, and experimental autoimmune encephalomyelitis at a potency and efficacy comparable to EPO.

Glutaraldehyde erythropoietin protects kidney in ischaemia/reperfusion injury without increasing red blood cell production.
BACKGROUND AND PURPOSE Recombinant human erythropoietin (rHuEPO) is currently the mainstay of renal anaemia treatment. Recently, rHuEPO has been shown to provide pleiotrophic tissue protection in various pathological conditions. However, the benefits of rHuEPO beyond anaemia treatment are limited because it increases red blood cell mass. Carbamylated erythropoietin (CEPO) is the first rHuEPO de...
متن کاملNon-erythropoietic tissue-protective peptides derived from erythropoietin: WO2009094172.
Erythropoietin (EPO) is a cytokine with erythropoietic and tissue protective activities. Its action as a tissue protective agent requires, however, high dosage that results in limiting side effects associated with abnormally augmented erythropoiesis. Elimination of the erythropoietic activity of EPO while preserving its tissue protective properties was nevertheless achieved in carbamoylated EPO...
متن کاملRenal Cell Protection of Erythropoietin beyond Correcting The Anemia in Chronic Kidney Disease Patients
Currently many patients with chronic renal failure have profited from the use of erythropoietin to correct anemia (1,2). In chronic kidney disease, anemia is believed to be a surrogate index for tissue hypoxia that continues preexisting renal tissue injury (1-3). Erythropoietin is an essential glycoprotein that accelerates red blood cell maturation from erythroid progenitors and facilitates ery...
متن کاملLow Oxygen Tension Primes Aortic Endothelial Cells to the Reparative Effect of Tissue-protective Cytokines.
Erythropoietin (EPO) has both erythropoietic and tissue-protective properties. The EPO analogues carbamylated EPO (CEPO) and pyroglutamate helix B surface peptide (pHBSP) lack the erythropoietic activity of EPO but retain the tissue-protective properties that are mediated by a heterocomplex of EPO receptor (EPOR) and the β common receptor (βCR). We studied the action of EPO and its analogues in...
متن کاملProtective effect of erythropoietin and its carbamylated derivative in experimental Cisplatin peripheral neurotoxicity.
PURPOSE Antineoplastic drugs, such as cisplatin (CDDP), are severely neurotoxic, causing disabling peripheral neuropathies with clinical signs known as chemotherapy-induced peripheral neurotoxicity. Cotreatment with neuroprotective agents and CDDP has been proposed for preventing or reversing the neuropathy. Erythropoietin given systemically has a wide range of neuroprotective actions in animal...
