Scientists find brain cell switch that could reverse obesity’s effects

High-fat diets and obesity reshape astrocytes—star-shaped brain cells in the striatum that help regulate pleasure from eating. French researchers discovered that tweaking these cells in mice not only impacts metabolism but can also restore cognitive abilities impaired by obesity, such as relearning tasks. This breakthrough highlights astrocytes as powerful players in brain function and energy control, opening fresh possibilities for targeted obesity treatments.
