TERT and airway hyperresponsiveness: In agreement with increased resistance to allergy induced by HDM, both G3 Tert−/− and 6‐thio‐dG treated mice showed improved lung function upon HDM challenge as determined by plethysmography, a well‐known technique for the determination of airway hyperresponsiveness (AHR) in murine models of allergic airway inflammation (Verheijden et al., 2014).
