A. Stimulation of sorted CD8+CD146+ T cells and CD8+CD146− T cells from healthy donors for 5 days in vitro with CD3/CD28 without the addition of any exogenous polarizing cytokines. PMA, ionomycin, and brefeldin A was added for the last 4 hours of this stimulation. Intracellular IFN-γ and IL-17A in CD8+CD146− T cells from a representative donor.
B. Intracellular IFN-γ and IL-17A in CD8+CD146+ T cells from a representative donor.
C. Composite results of these experiments from 14 healthy individuals. Significance was determined using the Wilcoxon matched pairs test and the bars indicate the mean SEM with 95% confidence intervals.
