Consistent with these results, we examined the levels of various immune cells in a separate experiment and found that the frequency of blood-borne and tumor-infiltrating activated cytotoxic CD8+ T cells was significantly higher in mice treated with both anti-PD1 and Ly6Ehi neutrophils relative to those treated with either monotherapy alone (Figures S4D–S4F). Here, CD8A is linked to neoplasm.
