Hypothesis
The study hypothesized that prolonging survival in CD118−/− mice would allow for the development of an adaptive immune response against HSV-1.
Conclusion
The absence of a functional type I interferon pathway leads to increased susceptibility to HSV-1 infection due to impaired T cell recruitment to the cornea.
Supporting Evidence
- Type I interferons are critical for controlling HSV-1 spread during infection.
- Mice lacking the type I IFN receptor showed significantly elevated viral titers.
- CD118−/− mice had reduced T cell recruitment to the cornea despite similar adaptive immune responses in lymph nodes.
Takeaway
Mice without a certain immune receptor are more likely to get sick from a virus because their body can't call for help from important immune cells.
Methodology
Mice were infected with HSV-1, and viral titers were measured in various tissues; flow cytometry was used to analyze immune cell populations.
Limitations
The study was limited by the inability to fully evaluate the adaptive immune response due to early mortality in CD118−/− mice.
Participant Demographics
C57BL/6J (WT) and CD118−/− mice, aged 6-10 weeks.
