mTORC1 suppression by Trp53 mutation drives resistance to immune checkpoint blockade.
p53 is a critical tumor suppressor gene that inhibits cancer development by regulating cell cycle arrest, apoptosis, DNA repair, and metabolism. Our findings demonstrate that certain p53 mutants, despite losing other canonical functions, retain wild type p53's ability to suppress mTORC1 and enhance autophagy, thereby inhibiting responses to immunotherapy.
