The impact of 30 μM ebselen or 7.5 mM NAC on the proliferation capacity in human PBMCs or CD4+T cells ex vivo isolated from fresh human blood derived from five different healthy donors, in the age group of 25–30 years supplemented ex vivo for three weeks. A &C denotes the impact in human PBMCs and B &D denotes the impact on CD4+ T cells. The bars indicate the mean ± S.D. Values statistically different from their controls (Student’s t-test, 95% confidence level) are indicated with an asterisk. * p < 0.05, ** p < 0.01, *** p < 0.001 - Significantly higher than the proliferative capacity of non-supplemented cells.
