Other chemokines found with elevated levels in BALF from active pulmonary TB patients compared to healthy subjects include CCL4 (macrophage inflammatory protein, MIP-1β), chemokine (C-X-C) motif (CXCL)-9 (or monokine induced by gamma interferon, MIG), and CXCL10 (interferon gamma-induced protein 10, IP-10) [34]. This evidence concerns the gene CXCL9 and pulmonary tuberculosis.
