EBV infection leads to life-long viral persistence. Although EBV infection can result in chronic disease and malignant transformation, most carriers remain disease-free as a result of effective control by T cells. EBV-specific IFN-gamma-producing T cells could be demonstrated in acute and chronic infection as well as during latency. Recent studies, however, provide evidence that assessing IFN-gamma alone is insufficient to assess the quantity and quality of a T-cell response. Using overlapping peptide pools of latent EBV nuclear antigen 1 and lytic BZLF-1 protein and multicolor flow cytometry, we demonstrate that the majority of ex vivo EBV-reactive T cells in healthy virus carriers are indeed IL-2- and/or TNF-producing memory cells, the latter being significantly more frequent in BM. After in vitro expansion, a substantial number of EBV-specific CD4(+) and CD8(+) T cells retained a CC-chemokine receptor 7 (CCR7)-positive memory phenotype. Based on their cytokine profiles, six different EBV-specific T-cell subsets could be distinguished with TNF-single or TNF/IL-2-double producing cells expressing the highest CCR7 levels resembling early-differentiated memory T cells. Our study delineates the memory T-cell profile of a protective immune response and provides a basis for analyzing T-cell responses in EBV-associated diseases.
