COVID-19 Infection May Drive EC-like Myofibroblasts towards Myofibroblasts to Contribute to Pulmonary Fibrosis.

ABSTRACT: COVID-19 has an extensive impact on Homo sapiens globally. Patients with COVID-19 are at an increased risk of developing pulmonary fibrosis. A previous study identified that myofibroblasts could be derived from pulmonary endothelial lineage cells as an important cell source that contributes to pulmonary fibrosis. Here, we analyzed publicly available data and showed that COVID-19 infection drove endothelial lineage cells towards myofibroblasts in pulmonary fibrosis of patients with COVID-19. We also discovered a similar differentiation trajectory in mouse lungs after viral infection. The results suggest that COVID-19 infection leads to the development of pulmonary fibrosis partly through the activation of endothelial cell (EC)-like myofibroblasts.

Project description:BackgroundIdiopathic pulmonary fibrosis (IPF) is a chronic and lethal lung disorder for which effective treatments remain limited. Recent investigations revealed a potential link between altered glucose metabolism and the activation of fibroblasts, the key cells responsible for generating and depositing extracellular matrix proteins within the lung interstitium during IPF development.MethodIn this study, we aimed to investigate the potential therapeutic impact of albendazole on fibroblast to myofibroblast transition in IPF. We assess albendazole's effectiveness in attenuating the activation of fibroblasts. We focused on elucidating the mechanism underlying albendazole's impact on TGF-β1-induced aerobic glycolysis in both lung tissues and fibroblasts obtained from patients with IPF and other lung fibrosis types. Furthermore, the antifibrotic effects of oral administration of albendazole were investigated in mouse models of pulmonary fibrosis induced by BLM or SiO2. Human precision-cut lung slices were employed to evaluate the impact of albendazole following TGF-β1 stimulation.ResultIn this work, we demonstrated that albendazole, a first-line broad-spectrum anthelmintic drug, effectively attenuated fibroblast to myofibroblast transition through alleviating TGF-β1-induced aerobic glycolysis dependent on the LRRN3/PFKFB3 signaling pathway. Additionally, LRRN3 expression was downregulated in both lung tissues and fibroblasts from patients with IPF and other types of lung fibrosis. Importantly, the levels of LRRN3 correlated with the progression of the disease. Notably, oral administration of albendazole exerted potent antifibrotic effects in mouse models of pulmonary fibrosis induced by BLM or SiO2, and in human precision-cut lung slices after TGF-β1 stimulation, as evidenced by improvements in lung morphology, reduced myofibroblast formation, and downregulation of α-SMA, collagen type 1 and Fibronectin expression in the lungs.ConclusionOur study implies that albendazole can act as a potent agonist of LRRN3 during fibroblast to myofibroblast differentiation and its oral administration shows potential as a viable therapeutic approach for managing IPF.
