 This study identified two gene networks associated with pulmonary fibrosis in mice. The first network was related to inflammation and fibroblast activation, while the second network was related to extracellular matrix remodeling. These networks were found to be highly conserved across species, suggesting that they may play a role in human pulmonary fibrosis. Additionally, the researchers identified CB1 are antagonists as potential therapeutic agents for treating pulmonary fibrosis. This article was authored by Mohamed Araf, Abhishek Basu, Kailin M.
