Interleukin 8 （IL-8 or chemokine （C-X-C motif） ligand 8, CXCL8） is a chemokine produced by macrophages and other cell types such as epithelial cells, airway smooth muscle cells and endothelial cells. Endothelial cells store IL-8 in their storage vesicles, the Weibel-Palade bodies. IL-8 is initially produced as a precursor peptide of 99 amino acids which then undergoes cleavage to create several active IL-8 isoforms. In culture, a 72 amino acid peptide is the major form secreted by macrophages. Interleukin-8 is a key mediator associated with inflammation where it plays a key role in neutrophil recruitment and neutrophil degranulation. IL-8 has also been implied to have a role in colorectal cancer by acting as an autocrine growth factor for colon carcinoma cell lines or the promotion of division and possible migration by cleaving metalloproteinase molecules. It has also been shown that IL-8 plays an important role in chemoresistance of malignant pleural mesothelioma by inducing expression of transmembrane transporters.
