CXCL2 and CXCL5 were the only two chemokine related genes whose RNA-seq (Supplementary Fig.S5B) results that were consistent with our qPCR results (Supplementary Fig. S5E), and the upregulation of CXCL2 and CXCL5 expression were the most significant, which was validated by qPCR analysis both in TB model and BT model (Supplementary Fig. S5C). This evidence concerns the gene CXCL2 and tuberculosis.
