Con A-induced cytotoxic activity of human lymphocyte subpopulations obtained by cell fractionation procedures was studied in a test system using human epipharynx carcinoma cells (HEp 2) as targets. Only T lymphocytes were cytotoxic, non-T cells exerted no cytotoxic activity, but enhanced the adherence of the tumour cells. Tnon-G lymphocytes (Fc-receptor negative T cells) were more active than TG cells (Fc-receptor-positive T cells) in mediating the Con A-induced cytotoxic reaction.
