Effects of C₆₀ derivatives on B cell responses. C₆₀-P, C₆₀(OH)₃₆, or N-acetylcysteine (NAC) was added to purified B cells 30 min before the addition of IL-4 and anti-CD40. After incubation of the cells for 10 days, the amount of total IgE in the supernatants was measured by ELISA. Data are means ± SDs for three to six independent cultures (n = 3 to 6). *P < 0.05 vs. control group
