Abstract
Fibrotic remodeling has become the result of many lung diseases, and these disorders can be categorized with known as well as unknown etiologies. Idiopathic pulmonary fibrosis is the most fatal disease among the unknown etiology. TGFβ1/Smad3 signal pathway plays an important role in lung fibrosis and epithelial regeneration. This study investigated the effects and mechanism of Feibi Recipe (FBR) on pulmonary fibrosis. In this experiment, C57BL/6 mice were used and bleomycin was used to induce the lung injury. Meanwhile, the study showed a significant reduction in pathological response and mediators of inflammation and fibrosis such as IL-6, ICAM-1, IL-13, IL-17, BRP-39, TGFβ1, Smad3, and Smad7 were identified. Collectively, the FBR appears to attenuate the lung injury and the modeling of fibrosis in mice.
