Behrens and his colleagues Kristina Blank and Wolfgang Meyerhof developed a way to screen which of the bitter taste receptors that saccharin and cyclamate were hitting, to figure out why the combination is more palatable than either one alone.

Bitter taste receptors are not only on the tongue but throughout the body, where they defend us against microbial invaders

According to new research from the Monell Center, cats have at least seven functional bitter taste receptors.

In our GI tract, bitter taste receptors can simultaneously promote the absorption of «safe» bitter compounds and the excretion of toxic ones, thereby preventing overexposure to the many low - grade food - borne toxins we eat every day.

The mechanism by which they stimulate boosted digestive capacity is wondrously simple: the bitter taste receptors on our tongue and other areas of the mouth register that a bitter compound has entered your body.

Essentially, those bitter taste receptors are trying to save you from your sweet tooth.

Thanks to research over the past 15 years or so, we now know that the bitter taste receptors in our mouths release neurotransmitters that stimulate, via the vagus nerve, an increase in intracellular calcium concentrations.

Not exact matches

Researchers were surprised to find receptors for bitter taste in the lungs, and more surprised that activating them caused airways to greatly relax.

Because scientists have discovered that the same receptors that exist on the tongue to taste bitter substances are also found on the smooth muscle of the lungs.

«Variation in bitter receptor mRNA expression affects taste perception.»

In the first study to show that the sensations from sampled alcohol vary as a function of genetics, researchers focused on three chemosensory genes — two bitter - taste receptor genes known as TAS2R13 and TAS2R38 and a burn receptor gene, TRPV1.

«In our research, we show that when people taste alcohol in the laboratory, the amount of bitterness they experience differs, and these differences are related to which version of a bitter receptor gene the individual has.»

Now, findings from Monell reveal that a person's sensitivity to bitter taste is shaped not only by which taste genes that person has, but also by how much messenger RNA — the gene's instruction guide that tells a taste cell to build a specific receptor — their cells make.

a) The Eye in your Thigh: a patch of skin cells on the leg that can distinguish between bright and dark conditions, perhaps to help regulate the body clock b) The Ear in your Rear: nerves in the buttocks attuned to infrasound vibrations of between 10 and 25 hertz, perhaps to warn of approaching predators or thunderstorms c) The Nose in your Toes: scent - detecting sebaceous glands on the feet whose purpose is unclear d) The Tongue in your Lung: taste - bud - like receptors that detect bitter substances and dilate or restrict the airways accordingly

In most animals, taste has evolved to avoid all things bitter — a key to survival — to avoid eating something that could be poisonous via taste receptors, known as Tas2r, that quickly spring into action and elicit the bitter sensation.

To do this, they incorporated the gene sequence of each receptor into cultured cells and then probed the cells to determine if they were activated by one or more of 25 different bitter - tasting chemicals.
