Distribution of α/β⁺ and γ/δ⁺ T cells and coexpression of BLR1 on these subpopulations on PBL derived from healthy (○; n = 15) or HIV-infected subjects (•; n = 69). PBL were stained with anti-BLR1-biotin/strepavidin-cychrome and were either incubated with anti-α/β⁺ TCR-FITC MoAb or with anti-γ/δ⁺ TCR-FITC MoAb. The percentage of T cells expressing α/β or γ/δ chains was calculated (A) and the percentage of BLR1⁺ cells in each subpopulation was determined (B). Results are the mean ± SD. ***P < .001 versus HIV⁻ control.
