Balb/c mice sensitized to OVA were subjected to repeated allergen exposure (OVA; 100 μg i.n. on five consecutive days).

Neutralizing anti-IL-9 (100 μg/animal i.p.) and anti-IL-5 (50 μg/animal i.p.) treatment or their isotype controls treatment, or single antibody in a combination with respective isotype control, were given before the allergen exposure. BAL was performed 24 hours after the last allergen exposure. Data represent mean ± SEM (n = 5 per point). * p < 0.05 and ** p < 0.01 compared with the isotype control antibodies treated group. IsC – isotype control.
