TCM- and TEM-derived CD8+ T-cell clones exhibit similar functional reactivity and both display an effector memory surface phenotype after culture in vitro. TCM- and TEM-derived SIV-specific CD8+ T-cell clones from two rhesus macaques, AZ15 and DBN2, were stimulated with PBMC pulsed with the appropriate peptides (A) or autologous SIV-infected CD4+ T-cell clones (B). IFN-γ-expression by the TCM- and TEM-derived clones was measured by ICS and flow cytometry. The surface phenotype of TCM- and TEM-derived clones was determined using flourochrome conjugated mAbs to CD28 and CD95 followed by flow cytometric analyzes (C).
