So the researchers bred mice that had no p11-producing gene. They acted depressed, and had fewer 1B receptors and less serotonin activity than regular mice. They also were less likely to improve with depression medication. Mice genetically altered to produce extra p11 acted in just the opposite way ? no depression-like behavior, and their brain cells carried extra serotonin-signaling receptors.
