Figure 6.
High versus low antigen-specific T-cell stimulation in vitro by IL-15DCs or IL-21DCs. DCs (□), IL-15DCs (▪), and IL-21DCs (▦) were labeled with different OVA323-339 peptide concentrations and incubated with lymph node cells from OTII mice. After 72 hours of incubation, cells were labeled with 0.2 μCi (0.0074 MBq) [3H]thymidine. One representative of 3 experiments is shown. Significance compared with DCs was calculated using Student t test (**P ≤ .01). Error bars indicate standard deviation.
