NELFCD and asthma: To confirm these in vitro results using an in vivo approach we used multiple mouse models of asthma‐like airway pathology that recapitulate either a classical Type 2 cytokine/eosinophilic‐dominant airways disease (through sensitisation and challenge with ovalbumin [OVA] or Alternaria alternata [AA]), or a more neutrophilic‐dominant airways disease characterized by elevated Th1 and Th17 cytokines induced by Chlamydia muridarum infection during OVA challenge.18, 19, 28, 29
