Expanded CD8 and CD4 clones are long-lived. HTLV-1 infected clones from 12 subjects were compared at two independent timepoints (the one studied above, and a second one at a median interval of 3.4 years). Clones here were grouped into bins of increasing log(absolute abundance). Only clones that were identified as CD4⁺ or CD8⁺ are shown here. For each abundance bin, the CD4⁺ and CD8⁺ clone data from each patient were compared to test the proportion of clones that were redetected at the second timepoint. Abundant clones (either CD4⁺ or CD8⁺) were likely to be redetected at a second timepoint. Within each abundance bin, CD8⁺ clones were redetected at least as frequently as CD4⁺ clones
