CXCL11 and infection: The chemokine ligand C-X-C motif chemokine ligand 11 (CXCL11), also known as IFN-inducible T cell α chemoattractant (I-TAC), mediates recruitment of T cells, natural killer (NK) cells and monocytes/macrophages at sites of infection, predominantly through the cognate G-protein coupled receptor CXCR3, like CXCL9 and CXCL10 (Colvin et al., 2004; Karin, 2020).
