Levels of IP-10/CXCL10 and IL-8/CXCL8 mRNA were higher in AM from patients with AFB-high active pulmonary TB (9.8±1.9, p<0.01 and 0.3±0.2, p<0.01, n = 6, respectively) than those of normal subjects (0.3±0.1 and 0.1±0.01, n = 8, respectively) (Figure 3A). This evidence concerns the gene CXCL8 and pulmonary tuberculosis.
