Abstract

DESCRIPTION (provided by applicant): This project aims to provide a translational model of adaptive and maladaptive responses to major stressors associated with trauma with the potential to not only provide novel insight into the etiology of PTSD but in addition to guide nove treatment developments for patients with PTSD. Our proposal aims to provide an integrative view on the functions of two major stress-response systems, the kappa opioid receptor system and glucocorticoids, which lays the foundation for future studies of these systems testing specific interventions for these patients. This proposal is a 3-year study involving thirty drug-naive participants in three study groups [PTSD, n=10; trauma-exposed healthy control subjects (TC), n=10; non trauma-exposed healthy control subjects (HC), n=10; age range 18-50 years, equal numbers of men and women in each cohort] who are to be recruited through public advertisement and invited to participate in a medical and psychiatric evaluation, neuroendocrine assessments, one MRI study and one PET study of kappa opioidreceptors using [11C]LY2795050 and PET.
