Altered Metabolism in Idiopathic Pulmonary Fibrosis

open access: yesJournal of Cellular Physiology, Volume 240, Issue 12, December 2025.
ABSTRACT Idiopathic pulmonary fibrosis (IPF) is an incurable lung disease that ultimately terminates in death or lung transplantation. It is characterized by a restrictive pattern with impaired diffusion capacity, and typically presents with repeated acute exacerbations that result in permanent and progressive loss of respiratory function.
