CD163 (Cluster of Differentiation 163) is a protein that in humans is encoded by the CD163 gene.[1] CD163 is the high affinity scavenger receptor for the hemoglobin-haptoglobin complex and in the absence of haptoglobin - with lower affinity - for hemoglobin alone.[2] It has also been shown to mark cells of monocyte/macrophage lineage.[3]
The molecular size is 130 kDa. The receptor belongs to the scavenger receptor cysteine rich family type B and consists of an 1048 amino acid residues extracellular domain, a single transmembrane segment and a cytoplasmic tail with several splice variants.
Clinical significance
A soluble form of the receptor exists in plasma, commonly denoted sCD163. It is generated by ectodomain shedding of the membrane bound receptor. sCD163 is upregulated in a large range of inflammatory diseases including liver cirrhosis, type 2 diabetes, macrophage activation syndrome, Gaucher's disease, sepsis, HIV infection, rheumatoid arthritis and Hodgkin Lymphoma.[5][6]
↑CD163 is the macrophage scavenger receptor for native and chemically modified hemoglobins in the absence of haptoglobin.
