In a study on violent aggression that included 16 aggressive male prison inmates from Norway, researchers found that immunoglobulin G (IgG) autoantibodies against adrenocorticotropic hormone (ACTH) exhibited differences in ACTH epitope-binding in the inmates compared with nonviolent control participants; when IgG and ACTH from aggressive participants were injected into mice in a behavioral experiment, the time elapsed until a resident mouse attacked an intruder mouse decreased, compared with when IgG and ACTH from control participants were used, findings highlighting potential molecular mechanisms underlying stress response and aggression in humans.
