Six days after the second treatment with Listeria-based immunotherapy treatment, mice were euthanized and tumors harvested and profiled for a. total number of GR1⁺CD11b⁺ MDSCs per 1e⁶ tumor cells. Ratios for CD8⁺/MDSCs (b) and CD8⁺E7⁺/MDSCs (c) were calculated. (*P ≤ 0.05, ** P ≤ 0.01, ***P ≤ 0.001). Experiment was repeated twice with n = 5/group with similar results
