Figure 3.

Antigenicity of analogs from three additional epitopes of tumor and viral antigens. IFN-γ production by CTLs specific for MAGEA2.157 (A), HBV Pol.455 (B), and HIV Pol.476 (C) in response to analogue-pulsed or wild-type (WT)-pulsed .221A2.1 cells is shown. The dotted line at each position demarcates the groups of five analogs with conservative/semiconservative substitutions (left of the line) and nonconservative substitutions (right of the line). Background IFN-γ responses were <25 pg/well.
