Duffy antigen is associated with:: (A) Cluster of Differentiation 123 (CD123), (B) Cluster of Differentiation 234 (CD234), (C) Cluster of Differentiation 345 (CD345), (D) Cluster of Differentiation 456 (CD456)
Answer is B. Duffy antigen/chemokine receptor (DARC), also known as Fy glycoprotein (FY) Associated with CD234 (Cluster of Differentiation 234) Duffy antigen is located on the surface of RBCs. Glycosylated membrane protein and a non-specific receptor for several chemokines. Receptor for the human malarial parasites Plasmodium vivax and Plasmodium knowlesi.
