Virus titres in asthma/A(H1N1)pdm09 mice were highest at 3 days post-infection, and decreased by 7 days post-infection, although the levels at this time point were still higher than that in any other group. In the present study, we investigated the sequential changes in intra-tracheal cytokine production, viral loads, and pulmonary inflammation in a mouse model of bronchial asthma during the first 7 days after A(H1N1)pdm09 or seasonal H1N1 influenza infection. In contrast, the levels in control mice increased to 161.4 pg/mL by 3 days post-seasonal virus infection, which were similar to those in asthma/A(H1N1)pdm09 mice (p = 1.00), and these levels were maintained until 7 days post-infection. The notable findings in the present study were the early peak in both IL-6 and TNF-α levels, the high inflammatory cell infiltration in BAL fluids, and the severe pulmonary inflammation at 3 days post-infection in asthmatic/A(H1N1)pdm09 mice. ./cache/cord-002659-566uoozj.txt ./txt/cord-002659-566uoozj.txt
