Interestingly, the immune response of tumor-bearing Pik3cg−/− mice was marked by increased anti-tumor cytotoxic molecules (IFN-γ, IL-17)) by T-cells and immune checkpoint marker (PD-L1, PD-1) expression by myeloid cells and T-cells compared to tumor-bearing wild-type mice. The gene discussed is IL17A; the disease is neoplasm.
