The genes with strongest induction included chemokines (e.g. CXCL11, 84-fold; CXCL10, 18-fold; CXCL9, 9-fold; CCL2, 9-fold) and cytokines (e.g. IL6, 54-fold; IL12B, 10-fold; IL1B, 9-fold;) etc. (Table 1) consistent with the infection of host phagocytes with Mtb reported earlier by us [33, 34]. This evidence concerns the gene CXCL11 and infection.
