Graphs represent the percentage of IFN-γmeasured in monocytes (left), T lymphocytes (middle), and B lymphocytes (right) by flow cytometry. BAG: 1.91 × 105 cells mL−1; BAC2: 1.91 × 106 cells mL−1; BAC3: 1.91 × 107 cells mL−1. NP-0.5 μg: 0.5 μg. NP-BAC1: 0.05 p,g-1.91 × 105 cells mL−1. NP-BAC2: 0.5 p,g-1.91 × 106 cells mL−1. NP-BAC3: 5 p,g-1.91 × 107cells mL−1. *p < 0.05, **p < 0.01, ****p < 0.0001.
