Interleukin-8(IL-8)is encoded by the IL8 gene and produced by macrophages and other cell types such as epithelial cells.It is also synthesized by endothelial cells,which store IL-8 in their storage vesicles.There are many receptors capable to bind IL-8,the most affinity to IL-8 are receptors CXCR1,and CXCR2.As a member of the CXC chemokine family,function of IL-8 is the induction of chemotaxis in its target cells,like neutrophil granulocytes,basophils,and T-cells.IL-8(72 a.a.)has a 5-10 fold higher activity on neutrophil activation,compared to IL-8(77 a.a.).IL-8 is often associated with inflammation,it has been cited as a proinflammatory mediator in gingivitis and psoriasis
