Effect of co-stimulation on cytokine production. PBMC from 18 SIV-vaccinated animals were stimulated with Gag peptides with and without costimulation then subjected to ICS. A and B are background values (no peptide stimulation) and C and D are peptide-stimulated, background subtracted values. * indicates P<0.05, ** P<0.001 to 0.01, Wilcoxon matched-pairs signed rank test. Bars represent the median.
