| Outline of Final Research Achievements |
To investigate the pathogenesis of acute exacerbations of asthma induced by viral infection, we examined bronchial resistance, peripheral blood and bronchial alveolar fluid (BALF) cells analyses and 23 types of cytokines/chemokines using an experimental asthma model mice infected with respiratory syncytial virus (RSV). The levels of BALF and tissue eosinophils showed significant increase in ovalbumin (OVA) and OVA/RSV groups compared with controls. MIP-1α in BALF was significantly increased in OVA/RSV groups compared with RSV groups, OVA groups, and control groups. Serum IL-5 in OVA groups and serum IL-17 in OVA/RSV groups were also higher than in controls. These findings suggest that eosinophilic inflammation via MIP-1α, IL-5, and IL-17 may play an important role in acute exacerbations of asthma model induced by RSV.
