We studied simultaneously Epstein-Barr virus (EBV)-specific CD4(+) and CD8(+) T cell responses during and after infectious mononucleosis (IM), using a previously described 12-day stimulation protocol with EBNA1 or BZLF1 peptide pools. Effector function of EBV-specific T cells was determined after restimulation by measuring intracellular interferon-gamma production. During IM, BZLF1-specifc CD4(+) T cell responses were dominant compared with CD8(+) T cell responses. EBNA1-specific CD4(+) and CD8(+) T cell responses were low and remained similar for 6 months. However, 6 months after IM, BZLF1-specific CD4(+) T cell responses had declined, but CD8(+) T cell responses had increased. At diagnosis, EBV-specific CD8(+) T cells as studied by human leucocyte antigen class I tetramer staining comprised a tetramer(bright)CD8(bright) population consisting mainly of CD27(+) memory T cells and a tetramer(dim)CD8(dim) population consisting primarily of CD27(-) effector T cells. The remaining EBV-specific CD8(+) T cell population 6 months after the diagnosis of IM consisted mainly of tetramer(bright)CD8(bright) CD27(+) T cells, suggesting preferential preservation of memory T cells after contraction of the EBV-specific T cell pool.
