Hypothesis

Does the immune response against B16 melanoma differ between 3-month-old and 12-month-old mice?

Conclusion

Older mice show increased resistance to tumor development from B16 melanoma cells compared to younger mice.

Supporting Evidence

  • NK activity decreases with age in mice.
  • 12-month-old mice are more resistant to tumor development than 3-month-old mice.
  • Natural antibody levels increase in older mice.

Takeaway

Younger mice get tumors from cancer cells more easily than older mice, but older mice have different immune responses.

Methodology

The study involved inoculating 3 and 12 month old mice with B16 melanoma cells and measuring immune responses over time.

Limitations

The study only included female C57BL/6 mice, which may limit the generalizability of the findings.

Participant Demographics

Female C57BL/6 mice aged 3 and 12 months.
