CXCL1/GRO alpha/KC/CINC-1 is an ELR+ angiogenic chemokine that interacts with CXCR2/IL-8 RB to attract and activate neutrophils. It is produced at sites of microbial infection by macrophages, monocytes, Kupffer cells, hepatocytes, endothelial and epithelial cells, cardiac and vascular smooth muscle cells, fibroblasts, melanocytes, mast cells, and neurons. CXCL1 function is associated with the development and extent of atherosclerosis, Alzheimer’s disease, and tumor angiogenesis.
