To study viral-induced exacerbations, mice were infected with influenza virus 2 weeks after the last LPS/elastase challenge, when the acute inflammation caused by LPS/elastase exposure had subsided ( Figure 2A ). Acute pulmonary dysfunction, neutrophilic inflammation and enhanced levels of proinflammatory cytokines such as IL-6 and TNFa have all been observed during exacerbations of COPD patients, indicating that the viral-induced inflammation in our mouse model is in line with that seen in humans. As we observed an increase of IL-1b protein in the lungs of LPS/elastase treated mice upon influenza infection ( Figure 3A ), we hypothesized that it also promotes innate immune responses and influences pulmonary function during exacerbations. ./cache/cord-273594-vmbhok1u.txt ./txt/cord-273594-vmbhok1u.txt
