The Duffy antigen receptor for chemokines in acute renal failure: A facilitator of renal chemokine presentation

Acute renal failure remains a major challenge in critical care medicine. Both neutrophils and chemokines have been proposed as key components in the development of acute renal failure. Although the Duffy antigen receptor for chemokines (DARC) is present in several tissues and a highly specific ligand for various chemokines, its exact role in vivo remains unclear.
