Expansion of Vβ 8 ⁺ T cells in SEB +  PPC treated mice after 48 hours. Balb/c mice (n = 3 per group) were injected i.p. with 100 μg SEB only (SEB), gavaged with 100 μL PPC at a concentration of 200 μg/mL (PPC only) or injected i.p. with 100 μg SEB and gavaged with 100 μL of PPC at 200 μg/ml TID for 2 days (SEB + PPC). The SEB + PPC and PPC only mice were also provided PPC at 200 μg/mL in their drinking water ad libitum for 48 hours. Naive mice received an i.p. injection of PBS. (A) The total number of CD3⁺/Vβ8⁺ cells, (B) CD3⁺/CD4⁺/Vβ8⁺ cells, and (C) CD3⁺/CD8⁺/Vβ8⁺ cells per lymph node are shown. Error bars represent standard deviation.
