哺乳动物的味觉受体及其介导的信号途径研究进展

摘要

Taste is one of the important physical sense of animals.Recent compelling evidence from rodent and human studies showed that in mammals there are 6 basic taste qualities：sweet,sour,bitter,salty,umami and fat.The progress of receptors and molecular mechanism for chemosensory transduction in taste buds has been made and reviewed within the last decade.%味觉是动物重要的生理感觉之一,众多研究结果表明,哺乳动物具有酸、甜、苦、咸、鲜（umami）、脂等六种基本味觉.近年来对于这六种味觉受体及其介导的信号途径的研究取得了很大进展,本文对此进行了综述.
