CXCL6 and melanoma: Based on an initial in vitro screen of SASP components, we here identified the chemokines granulocyte chemotactic protein‐2 (GCP‐2/CXCL6) and epithelial‐derived neutrophil attractant‐78 (ENA‐78/CXCL5), physiologically involved in neutrophil attraction to sites of tissue infection, to be upregulated in the skin of healthy old individuals and old but not young melanoma patients.
