Title: CHAC1 Is Differentially Expressed in Normal and Cystic Fibrosis Bronchial Epithelial Cells and Regulates the Inflammatory Response Induced by Pseudomonas aeruginosa Document date: 2018_11_29
ID: 10fe70kl_44
Snippet: In conclusion, we showed that inhibition of CHAC1 in bronchial epithelial cells resulted in the regulation of inflammatory mediators. Moreover, CHAC1 was induced preferentially in normal hAECBs in comparison to CF hAECBs in response to Pa and its virulence factors, LPS and flagellin. Thus, these results suggest that low CHAC1 expression may contribute to the excessive inflammation observed in CF bronchial epithelial cells after Pa infection and t.....
Document: In conclusion, we showed that inhibition of CHAC1 in bronchial epithelial cells resulted in the regulation of inflammatory mediators. Moreover, CHAC1 was induced preferentially in normal hAECBs in comparison to CF hAECBs in response to Pa and its virulence factors, LPS and flagellin. Thus, these results suggest that low CHAC1 expression may contribute to the excessive inflammation observed in CF bronchial epithelial cells after Pa infection and thus may be associated with the exacerbation of inflammation characterizing the lungs from patients with CF. Inflammation is complex and thought to have a critical impact during the course of CF lung disease (47) . A better understanding of the link between infection and inflammation is thus required for the development of new therapeutics.
