Induction of stress ligands in tumor cells by resveratrol. Cancer cells exposed to resveratrol upregulate stress proteins, such as death receptor 5 (DR5) or ligands for the immune receptor NKG2D including MICA or ULBPs. The engagement of these proteins by immune cells expressing the corresponding receptor (NKG2D receptor) or ligand (TRAIL), result in cancer cell death.
