IL-23 stabilizes an effector Treg program in the tumor microenvironment


ABSTRACT: Regulatory T cells (Tregs) are crucial for the maintenance of immune tolerance and restrict immunopathology during inflammation, yet they limit efficient anti-tumor immunity in the tumor microenvironment (TME). Effector Tregs (eTregs) are thought to be the cellular subset equipped with the strongest immunosuppressive and cancer promoting properties. Here we found by in preclinical cancer models, that Treg specific deletion of IL23R reduces tumor growth. Using heterozygous conditional knock-out mice in which Il23r KO and Il23r WT Tregs coexist in the same tumor microenvironment, we found that IL-23 sensing represents a crucial signal driving the maintenance and stabilization of eTregs involving the transcription factor Foxp3.
