Recognition of naturally processed WT p53 epitopes by A2.1-restricted CTL. The responder CTL line and clone specific for WT p53.187-197 and derived from p53−/− A2.1/Kb-Tg mice was (A) p53−/− A2Kb 187 and (C) p53−/− A2Kb 187 clone 4, respectively. The responder CTL line and clone specific for Hu WT p53.149-157 and derived from (p53+/+) A2.1-Tg mice was (B) A2 149 and (D) A2 149 clone 5, respectively. CTL lines and clones were assayed for cytotoxicity against the following targets: EA2Kb (open circles), EA2Kb.1p53 transfectants (closed circles), untreated p53-deficient Saos-2 (open squares), Saos-2 pretreated with IFN-γ and TNF-α (closed squares), untreated Saos-2/143 p53-transfectants (open triangle), and Saos-2/143 pretreated with IFN-γ and TNF-α (closed triangles).
