Severe steroid refractory asthma is often associated with neutrophilic inflammation, elevated Th17 cell numbers and IL-17A. A mouse model of allergen-driven severe asthma supports an association between Th17 responses and severe disease, and demonstrate that severely asthmatic animals have increased production of Th17 cytokines and responsiveness to IL-17A. %U https://www.jacionline.org/article/S0091-6749(17)32144-9/abstract
