Outline of Final Research Achievements |
(1)Clarithromycin (CAM) as a treatment of RSV infection and (2)disease-specific microRNA as an index of disease evaluation were examined.CAM treatment led to a significant reduction in RSV-mediated IL-8, CCL5, IFN-βand -λ production.Furthermore,IFN-β promoter activity (activated by poly I:C and RSV infection) was significantly reduced after treatment with CAM.CAM also inhibited IRF-3 dimerization and subsequent translocation to the nucleus.
RSV infection-specific secreted miRNAs were identified. Housekeeping gene of nasal secreted miRNA was identified.
