Zusammenfassung

Erythropoietin is well known to possess erythropoietic activity, but also tissue protection. Here, we present examples on how to separate these two activities. One possibility is to generate a short-lived variant by removal of EPO s sialic acid residues. Although asialo-EPO has a high affinity for the classical EPO-R, it lacks hematopoetic activity in vivo upon bolus injection, because of its short plasma half-life. Another approach we followed was to generate carbamylated EPO (CEPO), which has no affinity for the EPO receptor, but the same neuroprotective potency as EPO. Our data suggest that the cytoprotective signal transduction of EPO is distinct from the hematopoietic signaling machinery.
