CD163

A transmembrane protein encoded by CD163 on chromosome 12p13.3, which mediates the endocytosis of haptoglobin-haemoglobin complexes. CD163 belongs to the cysteine-rich scavenger receptor superfamily
Normal expression Highly expressed by tissue macrophages and less so by circulating monocytes. In a soluble form in plasma, it has an anti-inflammatory function.
Abnormal expression Expression is upregulated during inflammation by glucocorticoids, IL-10 and other modulators.
