Intracellular levels of Bcl-2 in Vβ 8
lymph node T cells 48 h post SEB injection. Balb/c mice (n = 3 per group) were treated as described in the Materials and Methods. The number of intracellular Bcl-2+/Vβ8+ lymph node T cells from the Naive (red line), SEB (purple line), and SEB + PPC groups (blue line) are shown in the bar graph (panel A) and the histogram in panel B. Error bars in panel A represent standard deviation. The histogram in panel C depicts the number of intracellular Bcl-2+/Vβ8- cells detected in the lymph nodes from the different treatment groups.
