Table 1 The number of blood samples with detectable Tax-specific CD8+ T-cells in all samples tested in this study

From: Functional impairment of Tax-specific but not cytomegalovirus-specific CD8+ T lymphocytes in a minor population of asymptomatic human T-cell leukemia virus type 1-carriers

Tax/HLA tetramers used in this study Disease Status
HLA-A*0201/Tax11-19 12/141 7/7 2/11
HLA-A*1101/Tax88-96 4/4 4/4 3/5
HLA-A*2402/Tax301-309 13/15 13/13 5/16
No. of tetramer+ samples/total no. of blood samples2 20/23 (87.0%) 18/18 (100%) 8/21 (38.1%)
  1. 1 No. of samples with detectable Tax-specific CD8+ T-cells/total no. of samples carrying each HLA allele. When the frequency of tetramer+ cells was more than 0.04% of CD8+ T-cells, the sample was regarded as detectable.
  2. 2 In case Tax-specific CD8+ T-cells was detectable by either tetramer in a sample carrying two of three HLA-A alleles above, the sample was regarded as positive.
