Abstract:

IL-9 overexpression protects against alveolar fibrosis induced by crystalline silica particles. This cytokine is also involved in allergic asthma. In the present study, we examined the effect of IL-9 overexpression on the subepithelial fibrotic response, a feature of asthmatic remodeling, induced by chronic exposure to Alternaria alternata extract. IL-9-overexpressing mice (Tg5) and their wild-type counterparts (FVB) were intranasally exposed to A. alternata extract or PBS (controls) twice a week during 3 mo. At the end of the allergic challenge, enhanced pause (Penh) measured in response t…
