Cytokine profile and antibody levels of peanut sensitised patients. A colour profile (A) and scatter plot (B) of IL-25 and IL-17 plasma levels (pg/ml) in children with a negative (n = 12) and children with a positive peanut challenge (n = 18). * p < 0.05 with a Mann–Whitney U test. Peanut-specific IgE (C) and total IgE (D) serum levels in the negative and positive challenge groups,* p < 0.05 with a Mann–Whitney U test. The positive challenge group is subdivided in IL-25 positive and IL-25 negative children.
