Explore how neutrophils shape the immune response in health and disease. This poster highlights neutrophil pathogen defense mechanisms, including phagocytosis, degranulation, and NETosis, as well as neutrophil roles in inflammation and NET-associated pathologies.
DOWNLOAD NOWCD163 is a member of the scavenger receptor family that has a role in inflammation.1,2 It is composed of an N-terminal ectodomain, which contains nine scavenger receptor cysteine-rich (SRCR) class B domains that mediate protein-protein interactions, a transmembrane segment, and a short cytoplasmic tail.1,3 Alternative splicing of the CD163 pre-mRNA produces several isoforms, including three variants that differ in length of the cytoplasmic tail.3 CD163 is expressed on the surface of monocytes and macrophages and used as a marker of M2 alternatively activated macrophages.1 CD163 protein levels are increased by hemoglobin, IL-6, IL-10, or glucocorticoids and decreased by LPS, IL-4, TNF-α, or IFN-γ.1,4 It binds to and internalizes haptoglobin-hemoglobin (Hp-Hb) complexes, leading to degradation of the Hp-Hb complex and production of anti-inflammatory heme metabolites.1 A soluble form of CD163 (sCD163), resulting from proteolytic cleavage of membrane-bound CD163, has been found in plasma and other tissue fluids.3 CD163+ macrophages in inflamed tissues or plasma sCD163 levels are increased in numerous acute or chronic inflammatory diseases, including sepsis, atherosclerosis, rheumatoid arthritis, and multiple sclerosis.1,2 Cayman's CD163 (N-Term) Rabbit Monoclonal Antibody (Clone RM371) can be used for immunohistochemistry (IHC) and Western blot (WB) applications.
