Fig. 2From: Enhanced synergistic antitumor effect of a DNA vaccine with anticancer cytokine, MDA-7/IL-24, and immune checkpoint blockadeProliferation of immunized BALB/c mice splenocytes after in vitro re-stimulation with synthetic E7 specific epitope. Splenocytes from mice were harvested one week after the last immunization, and MTT assay evaluated lymphocyte proliferation. Results represent the mean ± SD of 3 mice per groups. ***Statistically significant differences between the E7 DNA plus IL-24 adjuvant compared with other groups (E7 DNA, IL-24, pcDNA, PBS) as determined by one-way ANOVA (P < 0.001)Back to article page
