Hydrolysis of ATP suppressed MUC5AC augmentation of RV-induced inflammation in mice. Therapeutic suppression of mucin production using an EGFR antagonist ameliorated immunopathology in a mouse COPD exacerbation model. The coordinated virus induction of MUC5AC and MUC5B expression suggests that non-Th2 mechanisms trigger mucin hypersecretion during exacerbations. Our data identified a proinflammatory role for MUC5AC during viral infection and suggest that MUC5AC inhibition may ameliorate COPD exacerbations.]]> Tue 01 Nov 2022 11:18:46 AEDT ]]> Antiviral immunity is impaired in COPD patients with frequent exacerbations https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:36808 Thu 04 Nov 2021 10:39:56 AEDT ]]>
