Scientists find the key of brain cells that can reflect the effects of obesity

The brain key that can reflect obesity — Researchers show that stellar cells can be adjusted to reflect some of the changes that depend on obesity and metabolism, which reveals unarrgent therapeutic capabilities. Credit: Shutterstock

Diets and fatty obesity affect the structure of the star cells¹The brain cells are in the shape of the scheme, which is a brain area that is involved in the perception of fun resulting from food consumption. The most surprising thing is that by treating these star cells in vain In mice can affect metabolism and correct some cognitive changes associated with obesity (the ability to re -learn the task, for example). These results, which scientists describe from CNRS² Université Paris Cité recently published in the magazine Natural communication.

These discoveries reinforce the idea that the star cells (which have long been neglected in favor of neurons) plays a major role in the brain function. They also explain, for the first time, the ability of the stellar cells to restore the cognitive function in the context of obesity, and to open new ways to search to determine their precise role in energy metabolism.

These conclusions were reached using a combination of Former living and in vain Approval in rodents, including chemical techniques³Brain imaging, motion tests, cognitive behavior and measuring energy metabolism in the body.

Notes

Unlike neurons, stellar cells (nervous system cells) do not generate electrical activity, making them less easy to study in the past. However, thanks to the improvements in monitoring techniques, we now know that their close cooperation with neurons is necessary to work appropriate for the nervous system.
Reporting to the CNRS/PARISTé University. Scientists from the Paris Sin Institute of Biology (CNRS/Inserm/University) participated.
Calcium is an essential chemical component of the function of stellar cells, allowing adjusting the activity. The chemical technique used was based on the use of a virus, to express, in a targeted way in the stellar cells, a protein that can adjust calcium in the cell, such as the key. Thus scientists were able to study the effect of these calcium flows on the activity of the star cells and the surrounding neurons.
