Using monoclonal antibodies ( mAbs ) and flow cytometry, we studied a variety of surface receptors on lymphocyte subpopulations of workers with moderately increased body burdens of 2,3,7,8-tetrachlorodibenzo-p-dioxin ( TCDD ) and of other polychlorinated dibenzo-p-dioxins and dibenzofurans ( PCDD/PCDF ), expressed here as International-Toxicity Equivalencies ( I-TE ).
