Six months of TB therapy significantly decreased levels of major neutrophil-derived pro-inflammatory mediators: MMP1 (p = 4.90E−12 and p = 2.20E−07), MMP8 (p = 3.40E−14 and p = 1.30E−05) and MMP9 (p = 1.60E−04 and p = 1.50E−03) in plasma and sputum, respectively. Here, MMP9 is linked to tuberculosis.
