Figure 2: A. suum eggs and D. pteronyssinus extract upregulate production of IL-4 and IL-5. BALB/c mice were exposed to either A. suum eggs or D. pteronyssinus extract or both. Levels of IL-4 and IL-5 were measured at day 0, 36 and 72. P-values were determined using Repeated Measures Analysis of Variance (RMANOVA): p=x;y where x=day 0 vs day 36 and y=day 36 vs day 72. Results were presented as mean of the three trials because Mixed Model Analysis of Variance indicates that the results per trial do not significantly differ (p=0.132). A. IL-4 levels. B, IL-5 levels.
