Effect of in vitro exposure to QDs on spleen-derived lymphocytes. A Cell viabilities of lymphocytes treated with QDs for 24 or 48 h (n = 5). B and C Activation abilities of lymphocytes treated with QDs in response to ConA or LPS (n = 6). D, E The levels of TNF-α or IL-6 released by QDs-pretreated lymphocytes after re-stimulation with PBS or CpG (n = 6). All the values are the mean ± SD, *P < 0.05 vs. control, **P < 0.01 vs. control
