Immunophenotypic features of monoclonal TCRαβ⁺/CD4⁺/NKa⁺/CD8^−/+d T-LGL. Representative dot plots illustrate the phenotypic patterns shown by monoclonal TCRαβ⁺/CD4⁺/NKa⁺/CD8^−/+d T-LGL. Red dots correspond to monoclonal TCRαβ⁺/CD4⁺/NKa⁺/CD8^−/+d T-LGL, blue dots correspond to normal residual non-LGL CD4⁺ T cells, while gray dots correspond to PB leukocytes other than CD4⁺ T cells.
