Epstein-Barr virus (EBV) elicits primary CD8+ T cell responses that, by T cell cloning from infectious mononucleosis (IM) patients, appear skewed towards immediate early (IE) and some early (E) lytic cycle proteins, with late (L) proteins rarely targeted. However, L antigen-specific responses have been regularly detected in polyclonal T cell cultures from long-term virus carriers. To resolve this apparent difference between responses to primary and persistent infection, 13 long-term carriers were screened in ex vivo IFN-γ ELISPOT assays using peptides spanning the 2 IE, 6 representative E and 7 representative L proteins. This revealed memory CD8 responses to 44 new lytic cycle epitopes that straddle all three protein classes but, in terms of both frequency and size, maintain the IE > E > L hierarchy of immunodominance. Having identified the HLA restriction of 10 (including 7L) new epitopes using memory CD8+ T cell clones, we looked in HLA-matched IM patients and found such reactivities but typically at low levels, explaining why they had gone undetected in the original IM clonal screens. Wherever tested, all CD8+ T cell clones against these novel lytic cycle epitopes recognised lytically-infected cells naturally expressing their target antigen. Surprisingly, however, clones against the most frequently recognised L antigen, the BNRF1 tegument protein, also recognised latently-infected, growth-transformed cells. We infer that BNRF1 is also a latent antigen that could be targeted in T cell therapy of EBV-driven B-lymphoproliferative disease.
