EBNA-1-specific CD8+ T cell responses can be rescued by removal of CD4+ or CD25(hi) T cells from NPC PBMC. PBMC depleted of CD4+ T cell lines (black bars), CD25hi cells (hatched bars), or non-depleted PBMC (white bars) were stimulated with LCL and EBNA-1 specific CD8+ T cell responses were detected by IFN-γ ELISPOT after incubation with an EBNA-1 peptide pool. Results from a representative experiment are expressed as the number of EBNA-1-specific spot forming cells (SFC) per million input cells.
