CXCL9 and infection: In humans, CXCL9 [also known as MIG (monokine-induced by IFN-γ)], CXCL10 [IP-10 (IFN-γ-inducible protein 10)] and CXCL11 [I-TAC (T cell α chemoattractant)] are IFN-inducible chemokines and mediate recruitment of T cells, natural killer (NK) cells and monocytes/macrophages at the infection site, predominantly through their cognate G-protein coupled receptor, CXCR3 (Janatpour et al., 2001; Loetscher et al., 1996).
