Researchers Identify Potential Therapeutic Target for Management of Thirst Disorders
In a recent mouse-model study, published in Nature Neuroscience, researchers at University Hospitals (UH), Harrington Discovery Institute at UH, and Case Western Reserve University have now found that the cerebellum also controls thirst, a major function necessary for survival. Specifically, the research team found that a hormone, asprosin, crosses from the periphery into the brain to activate Purkinje neurons in the cerebellum. This leads to an enhanced drive to seek and drink water.
