Le Xu, Ph.D., examines the intricate processes underlying lung development and disease, with a focus on idiopathic pulmonary fibrosis (IPF). Xu explores the roles of genetic and cellular mechanisms, including the hedgehog pathway, FGF signaling, and epithelial-mesenchymal interactions, in driving lung fibrosis. Xu also highlights links between congenital diaphragmatic hernia (CDH) and lung development, suggesting that both mechanical and genetic factors contribute to lung hypoplasia. The discussion includes the development of advanced mouse models that replicate key aspects of human IPF, offering insights into fibrosis progression. Xu's research ultimately seeks to identify the causes of lung tissue abnormalities and pave the way for targeted therapies. Recorded on 10/10/2024. (#39460)
