TGFβ blockade is effective at inducing CD8 T cell influx (33, 34), and synergizes with radiation in other tumor types (35, 36); however whether blockade of TGFβ signaling in pancreatic tumors would synergize with radiation is unclear given that pancreatic cancer cells rely on TGFβ signaling to maintain radiosensitivity (37). Here, CD8A is linked to neoplasm.
