In this issue, Du and colleagues uncover that optineurin functions as a key regulator of IFNγ receptor (IFNGR1) stability in malignant cells. Loss of optineurin in colorectal cancer cells causes IFNGR1 degradation, leading to impaired IFNγ signaling, decreased MHC-I expression, and enhanced ability to evade adaptive immune control.See related article by Du et al., p. 1826.
