Human tongues can smell and contain the same odor receptors found in our noses

Taste cells in the tongue contain the same odor receptors as they invented our noses, researchers say. The findings indicate that the main elements of food taste, taste and smell work together on the tongue, rather than being first combined in the brain. The researchers were inspired to investigate whether human languages ​​could smell through snakes, which are known to sniff in the air by girl out their forks. By learning exactly how the sense of taste is created, experts say, we can one day develop taste-modifying agents to fight diet-related diseases.

Now researchers from Monell Chemical Senses The Center of Philadelphia and New York University have used genetic and biochemical methods to study human flavor cells grown in a dish.

The researchers found that human taste cells contain many of the same key molecules found in olfactory (odor) receptors in our noses.

Thereafter, the team used a technique called calcium formation to show that their taste cells respond to odor molecules in the same way as olfactory receptor sources.

Other tests by the researchers showed that a single taste cell on the tongue may contain both taste and odor receptors.

“Our research can help explain how odor molecules modulate taste perception,” says senior author Mehmet Hakan Ozdener, a cell biologist at Monell Center.

“This can lead to the development of odor-based flavoring agents that can help combat excess salt, sugar and fat intake associated with diet-related diseases such as obesity and diabetes,” he added.

For example, food can be made to taste sweeter than it really is, which helps to minimize the desire to eat more.

Although we usually think we know the characteristic flavors of food and drink through our taste of taste, it is our sense of smell that actually plays the most important role. In this process

Taste – which can identify bitter, salty, sour, sweet and umami (or tasty) molecules on our tongues – actually developed to help us evaluate nutritional and potential food toxicity.

however, our sense of smell gives us detailed information about the taste of the food – which allows us to distinguish between, say, strawberries and chocolate.

It had In the past, it was found that only in the brain was the taste and smell combined to create the overall sense of taste.

However, the result of the new study suggests that these two senses can come together much earlier than was thought.

Dr Ozdener was inspired by snakes to study whether human languages ​​could also melt l.

Snakes are known to girl out their receptor-full tongues to cheat the air.

With this initial study completed, the researchers are now working to determine whether the olfactory receptors on the tongue are mainly found in cells that specifically taste – like salt or sweet detecting cells.

Other planned studies will examine how odor molecules can alter the response of the taste cells and, by extension, our overall taste.

& # 39; The presence of olfactory receptors and taste receptors in the same cell gives us exciting opportunities to study the interactions between odor and taste stimuli on the tongue, Dr. Ozdener says.

In addition, the new results can also provide a new tool that scientists can study how we smell things – because it is still unclear which molecules activate the majority of the approximately 400 different types of human olfactory receptors. The flavor cells grown in the lab could be applied to assist screen molecules and identify those that activate given receptors.

The complete results of the study were published in the journal Chemical Senses.

HOW DOES THE HUMAN OLFACTORY SYSTEM WORK?

Smelling is a complex process.

The olfactory systems detect molecules in the air.

Inhaled in the nasal cavity, odor molecules come into contact with olfactory epithelial tissues in the nose.

Each molecule stimulates several chemical receptor cells.

The olfactory nerve transmits the information from the receptor cells to the brain for processing.

The transmitted information contains measures of odor intensity and quality.
