Cytokine and chemokine responses to Der p allergens and allergen‐derived peptides. Cultured PBMCs from individuals sensitized to the respective allergen (red) and individuals without HDM sensitization (black: n = 10) were incubated with allergens (Der p 1, Der p 2, Der p 5, Der p 7, Der p 21, Der p 23) and the corresponding allergen‐derived peptides (x‐axes) and cytokine and chemokine levels were measured in the supernatants (y‐axis: pg/mL). A, IL‐5, B, IL‐13, C, IFN‐gamma, D, IL‐10, E, IL‐17. Shown are box plots representing the first and third quartile. Horizontal bars denote medians and outliers are presented as circles. Statistically significant differences (**P < 0.01; *P < 0.05) are indicated
