This image of the mouse hippocampus, a part of the brain involved in learning and memory, shows mGluR3 receptors on astrocytes (green), neurons (red) and cell nuclei (blue). Credit: Orr Lab Weill Cornell Medicine scientists have uncovered the first evidence that astrocyte receptors can trigger opposite effects on cognitive function in male and female preclinical models. The findings point to astrocytes, brain cells that support and regulate neurons, as key contributors to sex-specific brain mechanisms. While many studies have tested the behavioral effects of astrocytic receptors, none of them have Read More
