In this study, we analyzed CD4 + and CD8 + T-cell responses in peripheral blood of recovered SARS patients to a pool of 169 overlapping SARS-CoV S peptides and characterized the phenotype of memory T-cell subpopulations. In this study, we performed phenotypic characterization of antiviral T-cell responses specific for SARS-CoV S peptides on the basis of their ability to secrete IFN-g and the expression of CD45RO, CCR7 and CD62L. Consistent with observations in HIV infection, we showed that SARS-CoV S-specific CD8 + T cells produced IFN-g but not IL-2 and predominantly displayed CD45RO À CCR7 À phenotype which might represent terminally differentiated effector memory T cells [25] . ./cache/cord-295508-yhdj5m0e.txt ./txt/cord-295508-yhdj5m0e.txt
