Figure 4. Increased donor-reactive T cell response in B6.CCR5−/− recipients and CD8−/−/CCR5−/− recipients.
Groups of wild-type C57BL/6, B6.CCR5−/− and B6.CD8−/−/CCR5−/− mice (n = 3/each group) received B6.Kd heart allografts. On day 10 post-transplant (A) whole spleen cell suspensions or (B) CD8 T cells enriched from recipient spleens by negative selection were tested by ELISPOT assay to enumerate cells producing IFN-γ and IL-4. Data are representative of two independent experiments and the data indicate mean number of donor-reactive T cells or CD8 T cells producing the test cytokine ± SEM. (A) **p =0.004 vs. wild-type C57BL/6 recipients and p = 0.009 vs. B6.CD8−/−/CCR5−/− recipients; *p = 0.012 vs. CCR5−/− recipients; (B) **p = 0.003 vs. wild-type C57BL/6 recipients.
