Similar to gut, pancreas, and hypothalamic neurons, in the tongue glucose transporters and ATP-sensitive K+ (KATP) channels are also involved in sugar detection. Among them, the KATP channel is the target for the antiobesity hormone leptin, which inhibits sugar-sensitive cells such as sweet taste cells, pancreatic ƒÀ-cells, and hypothalamic orexigenic neurons. Sugar signals from the taste organ elicit cephalic-phase insulin release, and those from the gut contribute to sweet preference for caloric sugars. All of these systems are indispensable for maintaining energy homeostasis. Thus, an exquisite system for sugar detection/signaling to regulate energy homeostasis exists in our body. en-copyright= kn-copyright= en-aut-name=YoshidaRyusuke en-aut-sei=Yoshida en-aut-mei=Ryusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YasumatsuKeiko en-aut-sei=Yasumatsu en-aut-mei=Keiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NinomiyaYuzo en-aut-sei=Ninomiya en-aut-mei=Yuzo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Oral Physiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Tokyo Dental Junior College kn-affil= affil-num=3 en-affil=Division of Sensory Physiology and Medical Application Sensing, Research and Development Center for Five-Sense Devices, Kyushu University kn-affil= en-keyword=gustatory nerve fibers kn-keyword=gustatory nerve fibers en-keyword=leptin kn-keyword=leptin en-keyword=cephalic-phase insulin release kn-keyword=cephalic-phase insulin release en-keyword=sweet taste kn-keyword=sweet taste en-keyword=food intake kn-keyword=food intake END
