Total numbers of variants of Tax 11-19 are 2, 1, 3, 9, 4, 1, 3, 2, and 1, in the order of amino acid position, respectively.
HTLV-1 proviral load is shown as copies/104 PBMCs.
HTLV-1 Tax 11-19-specific T-cell frequency in CD8+ cell population is shown.
Amino acid sequence is presented by the single letter. Underlined amino acids indicate mutations.
Percentage of variant epitope in the sequenced clones is shown at each time point.
HLA-A2-binding affinity by dissociation half-time (minutes) of each peptide is predicted through the Internet (http://bimas.dcrt.nih.gov/moibio/hla_bind/).
