Clinical evidence supports the notion that T cell exhaustion and terminal differentiation pose challenges to the persistence and effectiveness of chimeric antigen receptor-T(CAR-T)***1/2 inhibitors(MEKIs),widely used in cancer treatment due to their ability to inhibit aberrant MAPK signaling,have shown potential synergistic effects when combined with ***,the impact and mechanisms of MEKIs on CAR-T cells remain uncertain and *** address this,we conducted a comprehensive investigation to determine whether MEKIs enhance or impair the efficacy of CAR-T *** findings revealed that MEKIs attenuated CAR-T cell exhaustion and terminal differentiation induced by tonic signaling and antigen stimulation,thereby improving CAR-T cell efficacy against hematological and solid ***,these effects were independent of the specific scFvs and costimulatory domains utilized in ***,analysis of bulk and single-cell transcriptional profiles demonstrates that the effect of MEK inhibition was related to diminish anabolic metabolism and downregulation of c-Fos and ***,the overexpression of c-Fos or JunB in CAR-T cells counteracted the effects of MEK ***,our Cut-and-Tag assay revealed that MEK inhibition downregulated the JunB-driven gene profiles associated with exhaustion,differentiation,anergy,glycolysis,and *** summary,our research unveil the critical role of the MAPK-c-Fos-JunB axis in driving CAR-T cell exhaustion and terminal *** mechanistic insights significantly broaden the potential application of MEKIs to enhance the effectiveness of CAR-T therapy.
