Abstract excerpt
EBV isolates from human populations with a high frequency of HLA A11 evade recognition by CTLs specific for an immunodominant A11-restricted epitope derived from the EBV nuclear antigen 4 (EBNA-4). We have previously described four nonimmunogenic variants of this epitope carrying single amino aci...
