A hidden brain switch could change everything we know about hunger and fullness! 🧠
Scientists from the University of Maryland and University of Concepción discovered that astrocytes, brain cells once thought to just support neurons, actively signal when you’re full. After eating, tanycytes detect glucose and release lactate, which activates astrocytes. These astrocytes then communicate with neurons to suppress appetite, creating a full-body feeling of satiety.
This breakthrough could lead to innovative treatments for obesity and eating disorders by targeting astrocytes or the HCAR1 receptor. While still in animal models, the research offers a glimpse into a future where brain chemistry could help regulate healthy eating patterns.
