[Characterization of lymphokine-activated killer cells obtained from the natural killers--T cells of patients with hepatic tumor lesion].

To analyze the functions of lymphokine-activated killer cells (LAKC) and to study their phenotype are of paramount importance in the assessment of their role in antitumor immunity. The natural killers--hepatic T cells--have been shown to be used to prepare LAKS that have a higher cytotoxic activity than LAKS that are generalized from peripheral mononuclear cells.
