The virulence and transmissibility of this virus have intensified over time, posing significant challenges to the prevention and control of this pathogen.

Our findings showed no significant alterations in cell viability or lactate dehydrogenase (LDH) production in TQ-treated cells, while significant alteration in both factors was detected in cells treated with Sovaldi, the most commonly used drug for treatment of HCV infection. Interestingly, the level of the HCV NS5A protein was significantly reduced in infected cells treated with either TQ or Sovaldi in a dose-dependent manner. The expression of phosphorylated Raf-1 (phospho-Raf-1) and phospho-Mek-1 in infected cells was inhibited by TQ treatment, and the potential interaction between TQ and Ref-1 was confirmed by a molecular docking simulation. Unlike autophagy-related 12 (Atg12), the expression of LC3B in infected cells was also inhibited in a dose-dependent manner by TQ treatment. Conversely, the levels of interleukin-27 (IL-27) and interferon-alpha (IFN-α) in infected cells were significantly increased in a time- and dose-dependent manner by TQ treatment.

Several mutations in the S protein that are associated with vaccine escape were identified in samples of genotype C (I110L, S113T, T126I, T143S, Y161F) and B (K122R), some of which might have been from vaccinated individuals.
