Background

CD163, also known as M130 and  p155, is a 130-160 kDa type I transmembrane protein belonging to group B of the cysteine-rich scavenger receptor family (1). Mature mouse CD163 consists of a 1007 amino acid (aa) extracellular domain (ECD) with 9 scavenger receptor cysteine-rich (SRCR) domains, a 21 aa transmembrane segment, and a 55 aa cytoplasmic domain (2). Alternative splicing of mouse CD163 generates an isoform with a substitution in the cytoplasmic region. Within the ECD, mouse CD163 shares 75% and 90% aa sequence identity with human and rat CD163, respectively. CD163 is expressed on monocytes and macrophages and is inducible by immunosuppressant glucocorticoids and IL-10 (3-5). A soluble form is shed from the cell surface by TACE or neutrophil elastase mediated cleavage (6, 7) in response to oxidative stress, Prostaglandin F2a stimulation, or the activation of Fc gamma receptors, TLR1, 2, 5, or 6 (8-10). CD163 mediates monocyte binding to bacteria, leading to the release of inflammatory cytokines (11). It is essential for the circulatory clearance of hemoglobin-haptoglobin (Hb-Hp) complexes as well as free hemoglobin (12, 13). It can also mediate monocyte-erythroblast adhesion and promote erythroblast expansion (14). CD163 binds and internalizes the cytokine TWEAK, and the ratio of soluble CD163 to TWEAK in the plasma is elevated during atherosclerosis (15, 16).
