Dexamethasone prevents the Epstein‐Barr virus induced epithelial‐mesenchymal transition in A549 cells

Fengqin Zhang, Lei Chen, Ying Zhou, Dan Ding, more

Journal of Medical Virology > 92 > 12 > 3697 - 3708

Clinical data have shown that pulmonary interstitial fibrosis is likely to occur in the later stages of viral pneumonia. While viral infections are thought to cause chronic pulmonary interstitial inflammation and pulmonary fibrosis, it remains unclear if they promote pulmonary fibrosis by epithelial‐mesenchymal transition (EMT). In this study, human epithelial cell line A549 has been used to model...
