Research Abstract |
We found bronchial and alveolar epithelial cell senescence in lung tissues from patients with idiopathic pulmonary fibrosis(IPF), but not fibroblast senescence. These results suggest that the difference of responsiveness to microenvironment in each type of cells leads to tissue remodeling and pulmonary fibrosis. TGF-beta induced cell senescence in human primary cultured bronchial epithelial cells and SIRT6 inhibited it. To inhibit epithelial cell senescence may leads to prevent pulmonary fibrosis.
