Mature B cells are not involved in egg‐induced protection against AAI. A, Total number of cells, percentage of eosinophils and total number of eosinophils in BAL fluid as assessed by FACS. B, Total number of neutrophils, dendritic cells (DCs), T cells and B cells in BAL fluid as assessed by FACS. C, Cytokine concentration in medLN cell culture supernatants after 4d restimulation with OVA (10 μg/mL) measured by ELISA. D, OVA‐specific IgG1 and OVA‐specific IgE antibodies in serum measured by ELISA. All data are a summary of 2 experiments, n = 5‐12. Significant differences were determined by one‐way ANOVA following Dunnett's multiple comparisons test as indicated with *P < 0.05, **P < 0.01, ***P < 0.001 or by unpaired t test as indicated by ^# P < 0.05, ^## P < 0.01
