Hypothesis
Does HCV NS3/4A affect innate and adaptive immune responses in vivo?
Conclusion
HCV NS3/4A inhibits innate immunity but does not prevent T cell-mediated clearance of NS3/4A-expressing hepatocytes.
Supporting Evidence
- NS3 protein levels were comparable in human and mouse livers.
- NS3/4A reduced murine innate responses to synthetic dsRNA.
- Cytotoxic T cells effectively eliminated NS3/4A-expressing hepatocytes.
Takeaway
HCV can trick the immune system, but T cells can still get rid of infected liver cells.
Methodology
The study used human liver biopsies and transgenic mice to analyze the effects of HCV NS3/4A on immune responses.
Limitations
The study primarily used mouse models, which may not fully replicate human responses.
Participant Demographics
Five patients with chronic HCV infections and one control patient with liver disease not caused by HCV.
