Hypothesis
How do age and genetic strain affect the populations of immune cells in C57BL/6 and BALB/c mice?
Conclusion
The study reveals significant differences in T cell and antigen presenting cell populations between the C57BL/6 and BALB/c mouse strains, influenced by age.
Supporting Evidence
- C57BL/6 mice had higher proportions of CD8+ T cells than BALB/c mice at older ages.
- BALB/c mice showed more memory/activated T cells compared to C57BL/6 mice.
- Age-related changes in immune cell populations were observed in both strains.
Takeaway
As mice get older, their immune cells change in different ways depending on their genetic strain, which can affect how well they fight off diseases.
Methodology
The study used flow cytometry to analyze immune cell populations in the blood and spleen of male C57BL/6 and BALB/c mice at various ages.
Potential Biases
Potential bias due to the use of only two mouse strains and the exclusion of female mice.
Limitations
The study focused only on male mice and did not explore the effects of other environmental factors.
Participant Demographics
Male C57BL/6 and BALB/c mice aged 1, 3, 5, 10, and 18 months.
