Thyroid hormones regulate systemic glucose metabolism through incompletely understood mechanisms. Here the authors report that hepatic thyroid hormone receptor β mediates the effects of the thyroid hormone T3 on systemic glucose homeostasis by modulating GLP-1 levels through suppression of hepatic CYP8B1 expression and bile acid mediated inhibition of intestinal FXR signalling.
