A protein in the brain links body weight, metabolism and activity

For many obese people gaining weight is a vicious cycle. Scientists at the MDC have now uncovered a contributing factor: genetic variants linked to obesity cause the brain to produce too much of a protein called Cadm1. The result is a disruption in the regulation of body weight and changes in behavior and metabolism, as reported by Matthew Poy and his colleagues in Nature Neuroscience.
