Association of TLR9 SNPs and bacterial induction of COPD active smoker alveolar macrophage IL-8.

Supernatant IL-8 concentrations of alveolar macrophages, obtained from active smokers with COPD, incubated with the same three bacterial strains detailed in Fig 3, were measured. Shadings for wildtype, TLR9 (T1237C), and for TLR9 (T1486C) are as detailed in Fig 2.
