Hypothesis

Differences in susceptibility to Japanese encephalitis virus (JEV) infection in mice are related to their immune responses and viral replication.

Conclusion

Mice with different susceptibilities to JEV neuroinvasion did not show changes in viral tropism and host innate immune responses prior to viral entry into the central nervous system.

Supporting Evidence

  • 95% of C3H/HeN mice died by day 17 post-infection.
  • 40% of DBA/2 mice died by day 21 post-infection.
  • DBA/2 mice showed earlier and higher titers of neutralizing antibodies compared to C3H/HeN mice.

Takeaway

Some mice get really sick from a virus called Japanese encephalitis, while others don't. This study looked at why that happens.

Methodology

C3H/HeN and DBA/2 mice were infected with JEV and observed for mortality and immune responses.

Potential Biases

Potential bias in selecting symptomatic mice for analysis.

Limitations

The study primarily focused on two mouse strains, which may not represent all genetic variations in susceptibility to JEV.

Participant Demographics

Six-week-old female C3H/HeN and DBA/2 mice.
