Tumor growth curves (a, c, e) and animal survival (b, d, f) of C57Bl6 mice implanted with E0771 cells after CpG vaccine administered i.t. on day 0 and 7 (a-b), combination αPD1 + αCTLA4 mAb treatment administered i.p. on days 0, 3, and 6 (c-d), and isotype control mAb administered i.p. on days 0, 3, and 6 (e-f). a, c, e, data represent mean ± s.e.m. of n=5–7 tumors implanted into individual animals. d0 signifies the first day of treatment when tumors reached 100 mm3. Arrows indicate days therapy is given. * indicates significance by repeated measures ANOVA with Tukey’s post-hoc test, against all other groups if not specified; $ indicates significance against all other groups by log-rank test. a, b, e, and f are representative of two independent experiments; *, $ indicate p<0.05, ***, $ $ $ indicate p<0.005; n.s. indicates not significant (p>0.05).
