Proliferative responses.

Proliferative response (cpm) of CTL lines generated from patients 1 (A) and 2 (B), in response to DCs pulsed with the autologous Id (●), the allogeneic Id from the other patient (○), or an isotype-matched (▵) Id protein. (C) Inhibition by antibodies against MHC class I and class II or an isotypic control IgG on Id-induced proliferation of CTLs from patients 1 (▪) and 2 (■). These results are representative of 3 independent experiments.
