WebDuffy antigen is a minor red blood cell antigen, the absence of which confers some resistance to malarial infection. Intrinsic factor may be absent in pernicious anemia. PIG- A deficiency results in paroxysmal nocturnal hemoglobinuria. Spectrin is deficient in hereditary spherocytosis Enlarges RBC: A) Plasmodium vivax B) Plasmodium malariae WebThe Duffy glycoprotein is a receptor for chemicals that are secreted by blood cells during inflammation. It also happens to be a receptor for Plasmodium vivax, a parasite that … Duffy antigen/chemokine receptor (DARC), also known as Fy glycoprotein (FY) or CD234 (Cluster of Differentiation 234), is a protein that in humans is encoded by the ACKR1 gene. The Duffy antigen is located on the surface of red blood cells, and is named after the patient in whom it was discovered. The protein … See more It was noted in the 1920s that black Africans had some intrinsic resistance to malaria, but the basis for this remained unknown. The Duffy antigen gene was the fourth gene associated with the resistance after the genes … See more Biochemical analysis of the Duffy antigen has shown that it has a high content of α-helical secondary structure - typical of chemokine receptors. Its N-glycans are mostly of the … See more Historically the role of this antigen other than its importance as a receptor for Plasmodium protozoa has not been appreciated.
