When comparing the macrophage features from lung tissue and BALF cells in TB, we found that the gene expression profile of MM-CCL4 in lung tissue was similar to that of MM-CCL23 in BALF, with high expression of a series of chemokine genes, including CXCL9, CXCL10, CCL4, and CCL3. This evidence concerns the gene CXCL9 and tuberculosis.
