Cytotoxic activity of lymphocytes after stimulation by dendritic cells (DC) loaded with irradiated tumour cells. Peripheral blood lymphocytes (PBL), lymph node lymphocytes (LNL) or tumour infiltrating lymphocytes (TIL) were stimulated with autologous DC pulsed with irradiated tumour cells (DC-Tu irr). Cytotoxic activity of lymphocytes was evaluated against autologous tumour cells using 51Cr release assay. Effector: target ratio was 50: 1. Controls were non-stimulated lymphocytes. Data are individual percentage lysis values of 13 lymphocyte populations.
