C-X-C motif chemokine 5 or ENA-78 is a protein that in humans is encoded by the CXCL5 gene.[1][2]

Contents

Function

The protein encoded by this gene, CXCL5 is a small cytokine belonging to the CXC chemokine family that is also known as epithelial-derived neutrophil-activating peptide 78 (ENA-78). It is produced following stimulation of cells with the inflammatory cytokines interleukin-1 or tumor necrosis factor-alpha.[3] Expression of CXCL5 has also been observed in eosinophils, and can be inhibited with the type II interferon IFN-γ.[4] This chemokine stimulates the chemotaxis of neutrophils possessing angiogenic properties. It elicits these effects by interacting with the cell surface chemokine receptor CXCR2.[4] The gene for CXCL5 is encoded on four exons and is located on human chromosome 4 amongst several other CXC chemokine genes.[3][5] CXCL5 has been implicated in connective tissue remodelling.[4]

Clinical significance

CXCL5 plays a role in reducing sensitivity to sunburn pain in some subjects, and is a "potential target which can be utilized to understand more about pain in other inflammatory conditions like arthritis and cystitis."[6]
