Figure 2.
Peripheral blood CD8+ T cells in TAP1−/− mice and controls after infection with M. tuberculosis. 5 wk after infection, blood was obtained and stained with a CD8-specific antibody. The percentage of CD8+ cells in peripheral blood lymphocytes was determined by flow cytometry for four mice/ group. The bar represents the mean for each group. This difference was statistically significant using a Mann-Whitney test (P = 0.0022).
