Figure Legend Snippet: Sustained IL2 stimulation is responsible for the adjuvant effect of IL2Cx. A, TgTR1 cells were incubated with Trp1 peptide (1 µg/ml) and IL2Cx122 or IL2Cx25 (100 ng IL2/ml) in the presence of increasing concentrations of homologue IL2 mAb (JES6-5H4 or JES6-1A12, respectively). Seven days later T-cell expansion was evaluated. B, CD45.1 mice were adoptively transferred with 1 × 105 TgTR1 cells followed by BiVax prime. Five days later the mice were boosted with BiVax, BiVax/IL2Cx25(10 µg) (2 µg IL2 + 10 µg IL2 mAb) or BiVax/IL2Cx25(300 µg) (2 µg IL2 + 300 µg IL2 mAb). On day 12 the total numbers of TgTR1 cells were evaluated in spleens. C, Representative flow dot plots from the experiment in panel B, showing the percentage of TgTR1 cells (MHCII-CD45.2+) in spleen gating in total live cells. (n = 3 mice/group). Representative results are shown from at least 3 independent experiments.
Techniques Used: Adjuvant, Incubation
Figure Legend Snippet: PEG-IL2 is effective in expanding BiVax generated antigen-specific T cells. A, WT mice (3/group) were vaccinated with BiVax prime. Five days later the mice received boosters with BiVax, BiVax/IL2, BiVax/IL2Cx122 or BiVax/PEG-IL2. Seven days later the numbers of Trp1 tetramer+ T cells were evaluated in spleens. B, WT mice were inoculated s.c. with B16F10 cells and 7 days later, received a BiVax prime followed 5 days later by booster vaccines with BiVax, BiVax/IL2 or BiVax/PEG-IL2. Tumor size growth curves showing means with SD for each group. (n = 10 mice/group). C, purified CD8+ T cells from WT mice receiving BiVax prime-boost (5 days apart) and treated or not with PEG-IL2 were incubated with either B16F10 (PD-L1 low) cells, IFNγ-treated (PD-L1 high) B16F10 cells (pulsed with 1 µg Trp1) with or without PD-L1 mAb (10 µg/ml) and the numbers of IFNγ-producing cells were evaluated by EliSpot. Representative results are shown from at least 3 independent experiments.
