title: Depressed lectin-dependent cell-mediated cytotoxicity against adherent HEP-2 cells in patients with carcinoma of the uterine cervix.
abstract: Lectin-dependent cell-mediated cytotoxicity of peripheral blood mononuclear cells from patients with uterine cervix carcinoma was evaluated using human adherent 3H-TdR-prelabeled HEp-2 epipharynx carcinoma cells as targets at a 50:1 effector-target cell ratio with 25 micrograms concanavalin A/ml in a 24-h assay. Peripheral blood mononuclear cells from 13 patients with cervical carcinoma in stage IV failed to exert cytotoxicity against HEp-2 targets. In contrast, an increased survival (decreased detachment from the monolayer) of HEp-2 cells was observed in the presence of peripheral blood mononuclear cells from patients, this being significantly enhanced by addition of concanavalin A during the lectin-dependent cell-mediated cytotoxicity assay.
