Essential
- Researchers have discovered that certain nerve cells of the intestine detect a bacterial protein, Flagelline, and send a brain satiety signal. Similarly,
- The message goes through the vagus nerve, which is the communication route between the intestine and the brain. For example,
- Information therefore circulates in real time. Similarly, which is why scientists speak of “sixth sense” thanks to which the brain reacts in real time to bacterial signals of the intestine. However,
Why are some people hungry than others and are difficult to satisfy? Meanwhile, The answer comes from the neurons of our intestine. Meanwhile, Researchers from Duke University. In addition, in the United States, discovered that they were communicating with those of the brain and thus influenced appetite. Their our intestine would have “sixth study has just been published in the journal Nature.
A sixth neurobiotic sense between the brain and the intestine – Our intestine would have “sixth
But by what mechanism? When we eat, some intestinal bacteria release Flagelline, a protein. It is she who gives the signal to neuropods, intestinal nerve cells.
Neuropods have a Toll 5 type receiver (TLR5) which detects Flagelline. The presence of this protein is a signal that the person is full. Once the information is recorded by neuropods, they transmit the message to the brain, which regulates appetite.
This message involves the vagus nerve, which is the communication route between the intestine and the brain. The information therefore circulates in real time, which is why scientists speak of “sixth sense”. After sight. hearing, smell, touch and taste, the human species would therefore have another meaning, thanks to which the brain our intestine would have “sixth reacts in real time to bacterial signals of the intestine.

Less appetite with Flagelline
During their work, scientists have conducted experiences on mice divided into two groups: those to whom they administered Flagelline and those who did not receive them. The objective was to measure the impact of this protein on hunger.
The rodents fast overnight and then, the next day, had access to food. Results: The mice with Flagelline have eaten less than the others who have fueled their hunger and have gained weight. This shows that this intestine-end communication plays a role in regulating satiety.

“In the future, I think that these works will be particularly useful for the scientific community in the broad sense to explain how our behavior is influenced by microbes, Indicates Diego our intestine would have “sixth Bohórquez, the main author of the study, in a communiqué. It could be a key piece of the puzzle in pathologies such as obesity or psychiatric disorders.”
In France, 15 % of the population was obese in 2019, according to the Directorate of Research, Studies, Evaluation and Statistics (Drees) and 31 % overweight.
