Induction of MUC1-specific CTL responses in vitro. DCs generated from adherent PBMNCs of HLA-A*02–positive donors in the presence of GM-CSF, IL-4, and TNF-α were pulsed with synthetic peptides and used to generate a CTL response in vitro. Cytolytic activity of induced M1.1- (A) and M1.2- (B) specific CTLs was analyzed in a standard 51Cr-release assay using autologous DCs pulsed with the cognate peptide (M1.1 in A [♦]; M1.2 in B [▪]) or an irrelevant peptide (M1.2 in A [□]; M1.1 in B [⋄]; HIV peptide [▵] in both panels) as targets. E/T ratio, effector-target ratio.
