Scientists Discover Hormone FGF21 Can Reverse Obesity in Mice by Activating a Hindbrain Circuit

US scientists have found that the natural hormone FGF21 can reverse obesity in mice by activating a specific neural circuit in the hindbrain. The discovery reveals a weight-loss mechanism fundamentally different from GLP-1 drugs and opens a new avenue for obesity therapy development.

Researchers at the University of Oklahoma discovered that a natural hormone called FGF21 can reverse obesity in mice by activating specific neural circuits in the brain. This research was published on March 31 in the academic journal Cell Reports. The findings suggest potential therapeutic applications for treating human obesity. Obesity is a major health concern affecting millions of people worldwide. The researchers plan to conduct further studies to explore the hormone's effects in humans. This discovery may lead to new treatment approaches for metabolic disorders.
