CXCL8 and pulmonary tuberculosis: The levels of IP-10/CXCL10 and IL-8/CXCL8 mRNA from PBMC were significantly higher in patients with AFB-high active pulmonary TB (0.2±0.1, n = 6, p<0.01 and 3.0±0.8, n = 6, p<0.001, respectively) as compared with normal subjects (0.001±0.001 and 0.3±0.1, n = 8, respectively) (Figure 3B).
