Abstract

See full text

Provided are a posttraumatic stress disorder (PTSD) animal model in which dopamine receptor subtype 4 (D4R) is damaged or deficient, a method for preparing the same, a method for screening a drug for treating PTSD using the same, and a pharmaceutical composition for treating PTSD comprising a drug detected by the screening method. As it is identified that a specific type of dopamine receptor is associated with a mechanism for fear memory expression induced by long-term depression (LTD), the understanding of pathogenesis of PTSD may be heightened, the animal model exhibiting similar clinical conditions of PTSD and the method for preparing the same may be applied in analyses for stability and effectiveness of a therapeutic agent for PTSD and screening of a therapeutic drug. Further, an agonist of D4R contained in the composition has been approved by the US FDA and clinically used for psychiatric diseases such as schizophrenia, and thus may be immediately used for clinical applications for PTSD symptoms.
