一个单一的味觉细胞可以对范围很广的刺激产生反应。
A single taste cell may respond to a broad range of stimuli.
然而,因为未分离酸渗透到味觉细胞中,饲料的氢离子浓度和它的酸味感觉之间仅仅有一个中度相关性。
However, there is only a moderate correlation between the hydrogen ion concentration of a food and its perceived sourness due to the penetration of non-dissociated acids inside the taste cells.
他们通过假设味觉受体应该只在很少种类的组织(特别是舌味觉细胞)中被发现,把名单缩减到900个。
They screened these by assuming that a taste receptor would only be found in a small number of tissue types (specifically tongue taste cells). That whittled the list down to 900.
这项研究的研究者亚历山大·巴奇马诺夫说:“相同的味觉细胞都拥有这些机能:将二氧化碳转化为质子,当酸感刺激的时候能感应这些质子。”
"The same taste cell has all the machinery to turn carbon dioxide into protons and then detect the protons as sour taste stimuli," said Alexander Bachmanov, who was not involved in the study.
由长期从事味觉研究的研究员查尔斯·扎克带领的研究人员们,目前在哥伦比亚大学的医疗中心,对一些因基因变异丧失酸感应细胞的白鼠进行研究。
The researchers, led by longtime taste researcher Charles Zuker, now at Columbia University Medical Center, conducted the study using mice that had been genetically altered to lack sour-sensing cells.
细菌的味觉并不像那些拥有鼻子的多细胞生物,但它可能是一种原始的形式,随后进化成了多细胞生物那种形式的味觉。
Bacteria don't smell like multicellular organisms that have noses, but it could be a primitive form of what developed later.
任一个主要分布于舌头上皮层的呈许多圆球状或椭圆形的感应细胞群中,它构成味觉的终端器官。
Any of numerous spherical or ovoid clusters of receptor cells found mainly in the epithelium of the tongue and constituting the end organs of the sense of taste.
结论味蛋白和转导蛋白可能是味细胞的G-蛋白,但以味蛋白特异性表达为主,它们可能参与味觉的信号转导作用。
Conclusion The result of present study proved that both transducin and gustducin were taste G-protein and gustducin was high expressed. Both of them might be involved in taste signal transduction.
