Fig. 1.

Cytolytic activity of lymphocytes from RCC patients after stimulation with autologous-tumor-loaded DCs. Lymphocytes were stimulated or not with DC-Tu irr. Autologous tumor cell lysis (%) was measured 7 to 10 days after stimulation. Data are the individual values of 31 lymphocyte populations derived from 21 RCC patients. Lymphocytes were expanded immediately after taking or after freezing (*). Patients with cytolytic activity increased by DC-Tu stimulation are ranged on the left part, and with decreased activity on the right part of the figure
