Researchers have developed a humanized mouse model of pulmonary fibrosis, which may aid in advancing drug validation strategies. The model is being explored for its potential to mimic human pulmonary fibrosis, with various studies investigating its applications, including the testing of immune-mediated responses and the screening of antifibrotic drugs. Other animal models, such as ferret and organoid platforms, are also being investigated to study pulmonary fibrosis and its underlying mechanisms.
