Levels of Th1 (TNF-α and IL-2) and Th2 (IL-4 and IL-10) cytokine of spleen cells stimulated by positive peptides. Cells were treated with three positive peptides and secretion of TNF-α (A), IL-2 (B), IL-4 (C), and IL-10 proteins (D) was evaluated with the ELISA method. The results are presented as means ± SEM and the unpaired Student t test was used for statistical comparison among the PMA group, three epitope stimulated group and control group. ns P > 0.05, * P < 0.05, ** P < 0.01.
