HTLV-I Tax expression in CD4⁺ or CD8⁺ T cells.

PBMC from four HAM/TSP patients were cultured for 0 hr, 12 hr, 24 hr, and 48 hrs. HTLV-I Tax and p19 expression of the cultured cells was measured at each time point. Graphs show Tax expression in CD4⁺ or CD8⁺ T cells over time. The open circle (dotted line) indicates percentage of Tax expressing CD4⁺ T cells in total CD4⁺ T cells. The open square (solid line) indicates percentage of Tax expressing CD8⁺ T cells in total CD8⁺ T cells.
