Pulmonary fibrosis is an interstitial lung disease characterized by inflammatory injury and tissue structure destruction. Currently, there is a lack of effective therapeutic drugs for pulmonary fibrosis, and the mechanism is still unknown. Therefore, it is urgent to seek new targets for effective drugs. In pulmonary fibrosis, the level of autotaxin (ATX) in bronchoalveolar lavage fluid increases and stimulates the production of lysophosphatidic acid (LPA). The involvement of LPA receptors in activating a variety of G-protein-mediated signal transduction pathways leads to a range of related physiological effects, including pro-inflammatory signaling in epithelial cells, activation of transforming growth factor signaling, and stimulation of fibroblast accumulation. LPA receptor antagonists and ATX inhibitors have been concerned as new targets for pulmonary fiber therapy, and currently related drugs have entered clinical trials. In this paper, the pathophysiological effects of LPA and ATX in pulmonary fibrosis disease and related drug development progress were reviewed to provide reference information of new drug development for pulmonary fibrosis based on the ATX-LPA axis.
