IFNAR1 Degradation: A New Mechanism for Tumor Immune Evasion?

Type I interferons have been shown to play a major role in anti-cancer immunity. In this issue of Cancer Cell , Katlinski et al. describe tumor-induced degradation of type I interferon receptor IFNAR1 chain as a new immune-evasion mechanism in colorectal cancers. Stabilizing IFNAR1 inhibits tumor growth and improves immunotherapy efficacy.
