Relationships between HTLV-1 PVL in PBMCs or serum sIL-2R level and Tax-CTLs, CMV-CTLs, CD2⁻CD19⁺B cells, CD3⁺CD8⁺T cells, CD16⁺CD56⁺NK cells, or CD11c⁺monocytes. (A) Correlation between HTLV-1 PVL in PBMCs (x-axis) and the percentages of Tax-CTLs within lymphocytes (far left panel), CMV-CTLs within lymphocytes (near left panel), Tax-CTLs as a percentage of CD8⁺ lymphocytes (near right panel), and CMV-CTLs within CD8⁺ lymphocytes (far right panel). (B) Correlation between serum sIL-2R level (x-axis) and the percentage of Tax-CTLs within lymphocytes (far left panel), CMV-CTLs within lymphocytes (near left panel), Tax-CTLs as a percentage of CD8⁺ lymphocytes (near right panel), and CMV-CTLs within CD8⁺ lymphocytes (far right panel). (C) Correlation between HTLV-1 PVL in PBMCs (x-axis) and the percentages of CD2-CD19⁺ B cells within lymphocytes (far left panel), CD3⁺CD8⁺ T cells within lymphocytes (near left panel), CD16⁺CD56⁺ NK cells within lymphocytes (near right panel), and CD11c⁺ monocytes within the monocyte population (far right panel). (D) Correlation between serum sIL-2R level (x-axis) and the percentages of CD2⁻CD19⁺ B cells within lymphocytes (far left panel), CD3⁺CD8⁺ T cells within lymphocytes (near left panel), CD16⁺CD56⁺ NK cells within lymphocytes (near right panel), and CD11c⁺ monocytes within the monocyte population (far right panel).
