Scientists reveal the “meaning” of the hidden intestine that speaks to your mind

The new research, led by neuroscientists at Duke University for Medicine, Diego Bohrinoise, PhD, and M. Maya Kaelberer, PhD, and published in natureIt focuses on nerve cells and small sensor cells that line the colon epithelium. These common microbial protein cells and send quick messages to the brain that help reduce appetite.

But this is just the beginning. The team believes that this nervous meaning may be a broader platform to understand how the intestine discovers microbes, which affects everything from eating habits to mood – and even how the brain can form microbium in return.

“We were interested in whether the body could feel microbial patterns in an actual time and not just an immune or inflammatory response, but as a neurological response directed behavior in an actual time,” said Bouhuhwiz, a professor of medicine and neuroscience at the Duke University College of Medicine and VIPs.

The main player is Flageellin, an old protein found in the bacteria, a tail -like structure that bacteria use to swim. When we eat, some bacteria are released. Neuropods discover that, with the help of receptors called TLR5, and releases a message through the vague nerve – a major communication line for communication between the intestine and the brain.

The team, backed by the National Institutes of Health, suggested a bold idea: that the bacterial flageline in the colon can lead to a nervous signal to send an appetite signal to the brain-a direct microbial effect on behavior.

The researchers tested this by fasting the mice overnight, then gave them a small dose of Flagilin directly to the colon. Those mice ate less.

When the researchers tried the same experience in the missing mice of TLR5 receptors, nothing has changed. Mice continued to eat and gain weight, which is evidence that the path helps regulate appetite. The results indicate that Flallin sends a sign of “our enough” through TLR5, allowing the intestine to inform the brain that it is time to stop eating. Without this future, the message does not pass.

This discovery was directed by the authors of the main study Winston Liu, PhD in Medicine, PhD, Emily Alwi, both of whom are graduate students in the training program for medical scientists, and post -PhD fellow Nama Raycher, PhD that reveals their experiences that disrupting the path changed eating habits in mice indicating a deeper connection between the microbes of intestinal and behavior.

“In the future, I think this work will be particularly useful for the broader scientific community to explain how our behavior is affected by microbes,” said Bouhriks. “One of the next step is to investigate how to change the specified diets of the microbial scene in the intestine. This can be a major part of the puzzle in conditions such as obesity or mental disorders.”
