  • Title: [Modulation of T1R chemosensory receptors for sweet nutrients - new paradigms in metabolic regulation].
    Author: Maillet EL.
    Journal: Med Sci (Paris); 2011 Feb; 27(2):177-82. PubMed ID: 21382326.
    Abstract:
    Recent studies have demonstrated that the sweet-sensing receptors T1R2/3, thought to be "taste receptors" specifically expressed in lingual system, are also expressed and involved in the chemo-detection of sweetening molecules circulating in other organs. Researches that focus on their roles in intestinal absorption, metabolic regulation and glucose homeostasis, in particular, are increasing. Indeed, the sweet-sensing receptor could provide a new therapeutic target for certain metabolic disorders and diseases like obesity and diabetes. If the natural and artificial sweeteners agonists are diverse and well known, the "anti-sweeteners" antagonistic molecules are a class of compounds that received very little attention until now. Their potential roles and pharmacological relevance outside the taste system are discussed. Moreover, the recent finding that 2 major classes of compounds belonging respectively to the fields of medicine (fibrates) and agriculture (phenoxy-herbicides) are potent inhibitors of human T1R3 receptor is reported, raising new questions about their potential impact on human metabolism.
