Figure 3. Functional property of S-Ag
specific T cells disclosed on the basis of cytokine secretion. PBMCs
from all subjects were stimulated with or without mixed S-Ag peptides
plus anti-CD28 for 72 h. The culture supernatants were collected and
assessed for the production of IFN-γ (A), TNF-α (B), and
IL-17 (C) by ELISA. The difference in cytokine levels between
the negative control and S-Ag stimulation in four groups was analyzed
using Student’s t-test. The cytokine production by PBMCs upon
S-Ag stimulation in each of the four groups was analyzed by ANOVA.
Significant statistical difference was set at p<0.05 (*) and
p<0.01 (#); ns means not significant while bars represent mean
values.
