Figure 4.
Numbers of CD4/CD8 cell subsets per thymus in PNP-deficient mice as compared with C57BL/6J mice. From the total number of cells per thymus (Fig. 2) and the relative CD4/CD8 subset distribution (Table 2), the relative number of cells in each CD4/CD8 subset was determined as percentage of that for C57BL/6J. The cell numbers are reported as the mean ± SD. Letters indicate significant difference (P = 0.05) among strains and from the C57BL/6J control (group a).
