  • Scientists discover hidden brain switch that tells you to stop eating

Contesto

The brain's signal to stop eating originates from an unexpected cellular source, according to new research. Astrocytes, long considered mere support cells for neurons, have been found to play a central role in controlling appetite. After a meal, rising glucose levels first activate specialized cells called tanycytes. These tanycytes then send direct signals to the astrocytes located in key brain regions. Upon receiving this signal, the astrocytes themselves trigger the activation of the neurons responsible for creating feelings of fullness. This pathway establishes astrocytes as active regulators, not passive bystanders, in the feeding process. The discovery of this distinct neural circuit provides a fresh target for developing innovative treatments. Researchers suggest it could lead to new therapies for conditions like obesity and various eating disorders.
