CXCL11 and infection: In addition to stimulation of CXCL10, which was observed at different MOI of infection, MOI of 1 as well as 3, the induction of the closely related chemokine CXCL11 (Interferon-inducible T-cell alpha chemoattractant, I-TAC or IP-9), being at 19th position among up-regulated genes, was also confirmed by RT-qPCR (Fig. 3A).
