IL17A and allergic asthma: Since it was shown recently that IL-17 is central in the development of non-allergic asthma in obese mice and responsible for abrogating respiratory tolerance [26,27], we measured IL-17A concentration in serum and BAL fluid of mice: IL-17A was increased in the serum after AAI in both diets and reduced in tolerized mice, mainly in HFD (S2H Fig).
