Effect of dmLT on IFN-γ responses induced by SEB and PHA stimulation in PBMCs from adults and infants. IFN-γ concentrations in cultures with cells from (A) adults (n = 15) and (B) infants (n = 15) stimulated with increasing concentrations of dmLT alone (1 or 10 µg/ml) or with SEB or PHA. Bars represent mean with SEM of IFN-γ concentrations in culture supernatants. Statistical analysis was performed using the Friedman test with Dunn’s multiple comparison post-test. ns, not significant; P > 0.05.
