Research Abstract

This study has revealed (1) Endocannabinoids selectively enhance sweet taste via CB1 receptor on sweet sensitive taste cells, (2) Taste cells expressing T1R3, a sweet and umami taste receptor component, that are identified by using T1R3-GFP mice respond to various sweet and/or umami taste stimuli, (3) T1R3-GFP taste cells lacking T1R3, gustducin, or TRPM5 do not respond to taste stimuli, (4) T1R3-GFP taste cells express Gα11, 14, s, q, and i2 as Gα subunits other than gustducin.
