GM-pMC vaccine exhibited a greater therapeutic effect than ICIs in ICI-hyporesponsive tumor.

(a) Schema for tumor implantation and treatment. The mice were s.c. inoculated with tumor cells followed by treatment with GM-pMCs, ICIs i.p. (anti-CTLA-4 Ab + anti-PD-L1 Ab), or in combination. Tumor growth and survival were monitored until the mice died or were sacrificed, when tumors exceeded 20 mm diameter. (b–d) The MO4 tumor-bearing C57BL/6 mice were left untreated or treated with the OVA257-264 peptide-loaded GM-pMCs, the ICIs, or in combination. (b) Median tumor volume. (c) Tumor growth of individual mice. (d) Kaplan-Meier survival curves. Data from two independent experiments are shown (n = 15 mice). *p < .05, **p < .01, ***p < .001.
