Study highlights liver-brain communication's role in regulating eating patterns and obesity

A recent study published in Science highlights the role of the hepatic vagal afferent nerve (HVAN) in regulating eating patterns and weight gain. Researchers found that removing HVAN in mice corrected disrupted food intake and reduced weight gain from high-fat diets, suggesting it could be a target for obesity treatments. The study focused on how the liver communicates with the brain to manage circadian rhythms related to food intake. It showed that disruptions in this communication led to increased eating during light periods and significant weight gain. Severing the HVAN reversed these effects, indicating its importance in metabolic regulation. These findings provide new insights into the mechanisms of food intake and weight management. The research suggests that targeting the HVAN may offer new strategies for treating obesity by restoring proper communication between the liver and brain.
