Fig. 6.
The majority of HTLV-1 Env- and Tax-specific CD4+ T cells are not infected with HTLV-1.
This figure shows concomitant detection of intracellular Tax and IFN-γ expression in CD4+ T cells after 6 hours in vitro activation with peptides from a patient with HAM/TSP (TAF). Dot plots showed that the vast majority of Tax+cells came from the IFN-γ− fraction. This was representative of experiments on 5 different subjects; refer to Table 1.
