Newly Discovered Brain Neurons Hold Key to Energy Balance and Obesity

Summary: Researchers uncovered a new subtype of hypothalamic neurons, called Crabp1 neurons, that serve as powerful regulators of energy expenditure. Silencing these cells lowered activity, temperature, and fat burning, leading to obesity, while activating them increased locomotion, thermogenesis, and resistance to diet-induced weight gain. These neurons respond to environmental cues like cold, exercise, and light exposure, linking lifestyle factors to metabolic health. The findings introduce a ...
