Figure 1. Dexamethasone inhibition of T cell cytokine release. Whole blood samples were cultured in the presence of T cell mitogen phytohemagglutinin and increasing dexamethasone concentrations. Graphs show the mean and standard error of the burnout (•) and the control group () for (A) gamma interferon and (B) interleukin-10. Basal cytokine release in the absence of dexamethasone is shown in Table 4.
