Cytolytic activity of CD8+ CTLs after 1-week restimulation with antigen in vitro. Spleen CD8+ T cells from each group of animals were stimulated in vitro with 1.0 nM P18-I10 (a–c) or 5 nM β-gal peptide (d–f) for 1 week. Peptide-pulsed P815 cells were used as target cells in a 5-h 51Cr-release assay.
