For the treatment of anemia (from renal transplants or certain HIV treatment)

Associated Conditions

Darbepoetin alfa is used in the treatment of anemia. It is involved in the regulation of erythrocyte differentiation and the maintenance of a physiological level of circulating erythrocyte mass.

Mechanism of action

Darbepoetin alfa stimulates erythropoiesis by the same mechanism as endogenous erythropoietin. Erythropoietin interacts with progenitor stem cells to increase red cell production. Binding of erythropoietin to the erythropoietin receptor leads to receptor dimerization, which facilitates activation of JAK-STAT signaling pathways within the cytosol. Activated STAT (signal transducers and activators of transcription) proteins are then translocated to the nucleus where they serve as transcription factors which regulate the activation of specific genes involved in cell division or differentiation.
