To analyze the effect of DXM/lactoferrin-induced PMN-MDSCs on both systemic and local antitumor immune responses, IFN-γ+ CD8 T cells in PBMC and tumor tissue were tested by flow cytometers 24 h after transfer of DXM/lactoferrin PMN-MDSCs, Con PMN-MDSCs, or tumor PMN-MDSCs into B16 tumor-bearing mice. Here, IFNG is linked to neoplasm.
