General description

Interleukin-8 (IL-8)/CXCL8 is an important chemoattractant cytokine and activator of neutrophils. It is liberated from endothelial cells, gingival fibroblasts, neutrophils, monocytes and phagocytes in the gingival crevice. IL-8 belongs to the CXC subfamily. This gene is located on human chromosome 4q13.3.

The protein encoded by this gene is a member of the CXC chemokine family. This chemokine is one of the major mediators of the inflammatory response. This chemokine is secreted by several cell types. It functions as a chemoattractant, and is also a potent angiogenic factor. This gene is believed to play a role in the pathogenesis of bronchiolitis, a common respiratory tract disease caused by viral infection. This gene and other ten members of the CXC chemokine gene family form a chemokine gene cluster in a region mapped to chromosome 4q. (provided by RefSeq)

Biochem/physiol Actions

Interleukin-8 (IL-8) chemoattracts and activates neutrophils. It is involved in guiding neutrophils and oligodendrocytes to sites of infection. The protein also stimulates angiogenesis and tumor growth. It is also associated with inflammatory diseases.

Interleukin-8 (IL-8)/CXCL8 participates in the progression of peripheral muscle weakness in individuals with COPD (chronic obstructive pulmonary disease). It helps in the transport of neutrophils across endothelium, pulmonary epithelium and fibroblasts. CXCL8 induces adhesion of neutrophils to extracellular matrix proteins and cytokine-stimulated endothelial monolayers via interaction with CD11b/CD18 (β2-integrins).
