Chemokine ligand CXC motif chemokine ligand 11 (CXCL11), also known as IFN-inducible T cell alpha chemokine, primarily mediates the recruitment of T cells, natural killer (NK) cells, monocytes and macrophages at the site of infection via cognate G protein-coupled receptors CXCR3, such as CXCL9 and CXCL10 (31, 32). The gene discussed is CXCL9; the disease is infection.
