FIG. 7.

Effects of IM and 2-ME on STF-mediated suppression of TT-induced proliferative responses. PBMC were incubated with TT alone (2 μg/ml) or with STF (4 μg/ml) in the absence or presence of 2-ME or IM, and T-cell proliferation was determined. The data are shown as the mean percentage of suppression (standard deviation [SD]) of proliferation to TT in the presence of STF, alone or with the inhibitor IM or 2-ME, observed with PBMC from three different vaccinated volunteers.
