Outline of Final Research Achievements |
It has been hard to predict the treatment response of HCV-infected patients to the most advanced DAA-included therapy. Using ultra-deep sequencing technology coupled with phylogenetic analysis, this study was conducted to disclose the role of viral quasispecies in determining the treatment response to DAA-included anti-HCV therapy. As a result, it was disclosed that viral quasispecies changed dynamically and certain viral isolates were selected with the introduction of DAA-based therapy. The result of the study provides better understanding of the mechanism in the appearance of DAA resistance.
