Figure 6. Specific Vβ-expressing T cell deletion occurs in mice exhibiting donor-specific tolerance.

The frequency of specific Vβ−expressing T cells was measured at day 225 post BM transplantation for both CD4⁺ and CD8⁺ T cells in both spleen and lymph node for the four groups of mice defined in the box below the graph. Results are expressed as mean ± SEM and are summarized from the two independent experiments detailed in both Fig. 2 and Supplemental Figure 1 (total n = 3–6 mice per group as detailed in the parentheses next to each symbol in the symbol code box). Statistically significant differences are shown by the p values.
