IL-26 and IL-17A in children with dog allergen sensitization
To assess whether release of either of the Type 17 cytokines, IL-26 and IL-17A, are altered in subjects with confirmed dog allergen sensitization, we measured the protein concentration of each cytokine from frozen serum. Systemic concentrations of both IL-26 and IL-17A were markedly increased in allergen-sensitized children compared with control children (Fig. 1 ). No children in the control group had detectable serum IL-26.
