Endogenous processing of an inserted HLA B8–restricted CTL epitope within EBNA1. (A) Two HLA B8+ LCLs and the same LCLs transfected with either the EBNA1-FLR-GFP or EBNA1ΔGA-FLR-GFP expression constructs were used as targets in a standard 51Cr-release assay to assess CTL activity to a B8-specific CTL clone, LC13. An E/T ratio of 5:1 was used in this assay. (B) C1R.B8 LCLs, C1R.B8.ICP47 LCLs, and the same LCLs infected with a recombinant adenovirus encoding full-length EBNA1 (Ad-EBNA1-FLR) were used as targets in a standard 51Cr-release assay to assess CTL activity. An HLA B8–restricted FLR-specific CTL clone, LC13, was used as an effector in this assay. An E/T ratio of 5:1 was used in this assay. These data are a representation of two separate experiments.
