Cytokine secretion pattern of HD-aAPC– and LD-aAPC–induced CD8⁺ CTLs of D2. CTLs were coincubated with LCL721 cells or T2 cells loaded with different amounts of HA-1^H peptide and the amount of cytokines determined in the cell supernatants. All cytokines were below 6 pg/mL in controls used (medium, medium with CTLs, and medium with T2 cells not loaded with peptide).
