![Figure 2. Antigen-induced neutrophilic airway inflammation in OTII mice. Wild-type (WT) or OTII mice were treated with 50 μg of OVA or KLH in PBS, or PBS alone intranasally for 3 days (once per day). Data in panels A-C, E are the average + SD of results pooled from 2 independent experiments, each of which gave similar results (n = 7-10). (A) Cells in BALF were quantified 24 hours after the last inhalation of OVA, KLH, or PBS. *P < .01; †P < .01 versus corresponding values for PBS-, OVA-, or KLH-treated wild-type mice and PBS- or KLH-treated OTII mice, respectively. (B) OVA-specific IgG1 and IgE in sera collected from mice in panel A 24 hours after the last OVA or PBS inhalation. (C) Airway responses (Penh and lung resistance [RL]) to methacholine were assessed 24 hours after the last inhalation of OVA, KLH, or PBS, as in panel A; BL indicates baseline. *P < .05 versus corresponding values for each of the other groups (by analysis of variance).
