The metabolic action of GLP-1-GIP-lanifibranor is blunted in mice with genetic or pharmacological inhibition of GLP-1R, GIPR or PPARδ and is absent in DIO double incretin receptor-knockout mice, collectively suggesting that GLP-1-GIP-lanifibranor has substantial therapeutic value in the treatment of obesity and diabetes. Here, GCG is linked to obesity disorder.
