    Skeletal muscle signals to brain, brown fat to control aging in mice
    The molecule mimecan — released from. Credit: skeletal muscle — helps neurons that activate brown fat maintain the length of their primary cilia (red). Restoring mimecan levels in older mice to that of younger mice helps maintain the length of the cilia and extends lifespan in older mice. Cell nuclei are in blue. Credit: Kentaro Mori

    Open lines of communication between the body’s organs are important to health and often falter with age. A new study in mice by researchers at WashU Medicine shows how signals that travel from skeletal muscle to the brain and then activate brown fat and control core body temperature are weakened in elderly mice. The research suggests that finding ways to restore these signals could offer new opportunities to support healthy aging.

    The study—led by S...
