Supernatant IL-8 concentrations of alveolar macrophages, obtained from ex-smokers with COPD, incubated with nontypeable Haemophilus influenzae 11P6H1 (Panels A), Moraxella catarrhalis 6P29B1 (Panels B) and Streptococcus pneumoniae 25P55S1 (Panels C), were measured at 6 hours. Analysis is shown for TLR9 wildtype (dark shading) compared with TLR9 (T1237C) (light shading) on left panels. Analysis for TLR9 wildtype (dark shading) compared with TLR9 (T1486C) (striped shading) is shown in right panels. Results are shown as box plots for each group. Each box encompasses the 25th to 75th interquartile range, with the horizontal line in each box representing median values. Each vertical bar encompasses the 10th to 90th percentile ranges. Values correspond with data given in Table 6.
