Note This 3R variant escaped from killing by Gag-epitope-specific CTL clonal lines when presented as an endogenously expressed sequence on transformed cells, but was recognized when exogenously loaded as synthetic peptide. A processing or epitope presentation mutation is assumed. Only 1/8 screened A24-positive individuals had CTL activity against this mutant.
