| CD8+ lymphocytes | 548 | 420 | 19,075 | 782 | 57,120 |

Pooled leukocytes isolated from the brains of naive or treated mice were counted and stained for flow cytometric analysis. To obtain the total number of each cell type present in each brain, the total number of leukocytes per mouse from each group was multiplied by the percentage of cells staining positive for the cell marker. Leukocytes were pooled from 10 mice per group. The experiment was performed twice, with similar results.
