The Pharmacochaperone Activity of Quinine on Bitter Taste Receptors
Bitter taste is one of the five basic taste sensations which is mediated by 25 bitter taste receptors (T2Rs) in humans. The mechanism of bitter taste signal transduction is not yet elucidated. The cellular processes underlying T2R desensitization including receptor internalization, trafficking and degradation are yet to be studied. Here, using a combination of molecular and pharmacological tech...
متن کاملRat taste behaviors for bitter and sour aversive stimuli
The gustatory and olfactory systems are the only two systems in which stimuli act directly on the receptor. There are five taste categories which have been identified as gustatory stimuli: sweet, salty, bitter, sour, and umami (MSG). Bitter and sour are known as aversive stimuli and help mammals avoid toxic and spoiled foods. Although both are similar in that they are aversive, they work throug...
متن کاملThe neuronal and molecular basis of quinine-dependent bitter taste signaling in Drosophila larvae
The sensation of bitter substances can alert an animal that a specific type of food is harmful and should not be consumed. However, not all bitter compounds are equally toxic and some may even be beneficial in certain contexts. Thus, taste systems in general may have a broader range of functions than just in alerting the animal. In this study we investigate bitter sensing and processing in Dros...
متن کاملThe contribution of taste bud populations to bitter avoidance in mouse strains differentially sensitive to sucrose octa-acetate and quinine.
Mice of the SWR/J (SW) strain avoid orally delivered sucrose octa-acetate (SOA), whereas the mice of the C3HeB/FeJ (C3) strain are insensitive to SOA. Mice of both strains and of a congenic strain (C3.SW) that shares more than 99% of the C3 genome, were tested in a taste-salient brief-access taste test for responses to SOA and quinine hydrochloride, before and after transection of the glossopha...
متن کاملBrain Response to Aversive Taste for Investigating Taste Preference
To clarify the intrinsic food preference mechanism, we investigated brain neurophysiological responses to unpleasant gustatory stimuli using electroencephalogram (EEG) and near-infrared hemoencepalogram (NIR-HEG) simultaneously. A conventional delayed response task based on Go/Nogo paradigm was adopted to extract real brain response components from spontaneous background signals. We found exces...
