Obtained: 13 June 2014 Accepted: 21 AugustConclusions Collectively, our success propose that the Th2 cytokine atmosphere which prevails in allergic asthma could promote greater production of pro-inflammatory mediators by AEC in response to respiratory viral infection, but is unlikely to play a purpose in any impairment of antiviral host defences in asthmatics.Abbreviations AEC: Airway epithelial cells; dsRNA: Double-stranded RNA; HPRT: Hypoxanthine-guanine phosphoribosyltransferase; IFN: Bradykinin B2 Receptor (B2R) Modulator Biological Activity Interferon; IL: Interleukin; RV: Rhinovirus(es); TLR: Toll-like receptor; TSLP: Thymic stromal lymphopoietin. Competing interests The authors declare that they have no competing interests. Authors’ contributions CH supervised the studies on MLE-12 cells as well as molecular biological research on human AEC. Q-XZ carried out the cell culture and enzyme immunoassays for human AEC. RS carried out the cell culture and many of the molecular biological scientific studies on MLE-12 cells. LG performed the molecular biological research on human AEC. BO supervised a lot of the human AECReferences 1.
