Figure 2. IL-4, IL-10 and IFN-γ production. DCs transduced with Ad-eGFP, Ad-m4-1BBL, Ad-tPSMA, Ad-tPSMA-IRES-m4-1BBL or none were co-culture with T cells. Supernatants were harvested for IL-4, IL-10 and IFN-γ production assay by ELISA. Data were shown as mean ± SD. Similar results were obtained from three independent experiments. *p < 0.05.
