Proliferative response (cpm) of CTL lines.

Responses generated from patients 1 (A), 2 (B), 3 (C), and 4 (D), in reply to DCs pulsed with the autologous Id protein (▴), tumor lysate (●), or autologous primary myeloma cells (○). Controls included DCs alone (▪) and DCs pulsed an allogeneic tumor lysate from another patient (■). In this study, patients 1 and 2 served as controls for each other, as did patients 3 and 4. Results are representative of 3 independent experiments.
