Figure 1: Increased memory T cells in blood and spleens pet shop mice.
Memory CD4 and CD8 T cell populations were analyzed by flow cytometry in the blood and spleens of SPF C57BL/6 mice and pet shop mice. Plots show antigen experienced CD44hi CD4 T cells and CD4-negative lymphocytes. Data are similar to other experiments where CD8 staining was used. Antigen-experienced T cells were measured, quantified, and differences assessed by t-test. N=4 mice per group, **p < 0.01.
