CD8A and neoplasm: While both 3M‐LNP/mRASwt and LNP/mKRASG12D treatment could be seen to increase CD8+ T cell expression at the tumor site compared to the saline control, the administration of 3M‐LNP/mKRASG12D solicited the highest cell density, which was significantly different from the other treatment groups (p < 0.001).
