target relevance
Interleukin 8 (IL-8 /CXCL8) is secreted primarily by macrophages and monocytes. It is one of the key mediators for inflammatory responses. IL-8 is a strong chemotractant for neutrophils and monocytes promoting activation of these cells by binding to two cell surface receptors, CXCR1 and CXCR2. It is also a strong angiogenic agent and is considered to play a role in the pathogenesis of bronchiolitis.

Gene names CXCL8,CXCL8 IL8
Protein family Intercrine alpha (chemokine CxC) family
Mass 11098Da
Function FUNCTION: Chemotactic factor that mediates inflammatory response by attracting neutrophils, basophils, and T-cells to clear pathogens and protect the host from infection (PubMed:18692776, PubMed:7636208). Also plays an important role in neutrophil activation (PubMed:2145175, PubMed:9623510). Released in response to an inflammatory stimulus, exerts its effect by binding to the G-protein-coupled receptors CXCR1 and CXCR2, primarily found in neutrophils, monocytes and endothelial cells (PubMed:1840701, PubMed:1891716). G-protein heterotrimer (alpha, beta, gamma subunits) constitutively binds to CXCR1/CXCR2 receptor and activation by IL8 leads to beta and gamma subunits release from Galpha (GNAI2 in neutrophils) and activation of several downstream signaling pathways including PI3K and MAPK pathways (PubMed:11971003, PubMed:8662698). {ECO:0000269\|PubMed:11971003, ECO:0000269\|PubMed:11978786, ECO:0000269\|PubMed:1840701, ECO:0000269\|PubMed:18692776, ECO:0000269\|PubMed:1891716, ECO:0000269\|PubMed:2145175, ECO:0000269\|PubMed:2212672, ECO:0000269\|PubMed:7636208, ECO:0000269\|PubMed:8662698, ECO:0000269\|PubMed:9623510}.
Subellular location SUBCELLULAR LOCATION: Secreted.
Structure SUBUNIT: Homodimer (PubMed:31235521). Dimer formation is disrupted by tick evasin-3 (PubMed:31235521). Interacts with TNFAIP6 (via Link domain); this interaction interferes with chemokine binding to glycosaminoglycans. {ECO:0000269\|PubMed:24501198, ECO:0000269\|PubMed:31235521}.
Post-translational modification PTM: Several N-terminal processed forms are produced by proteolytic cleavage after secretion from at least peripheral blood monocytes, leukcocytes and endothelial cells. In general, IL-8(1-77) is referred to as interleukin-8. IL-8(6-77) is the most promiment form. {ECO:0000269\|PubMed:11023497, ECO:0000269\|PubMed:11978786, ECO:0000269\|PubMed:2145175, ECO:0000269\|PubMed:2212672, ECO:0000269\|PubMed:2523801, ECO:0000269\|PubMed:2648135}.; PTM: Citrullination at Arg-27 prevents proteolysis, and dampens tissue inflammation, it also enhances leukocytosis, possibly through impaired chemokine clearance from the blood circulation. {ECO:0000269\|PubMed:18710930, ECO:0000269\|PubMed:19608678}.; PTM: (Microbial infection) Cleaved by group A Streptococcus protease SpyCEP; leading to impaired neutrophil endothelial transmigration and thus increased virulence. {ECO:0000269\|PubMed:18692776}.
