Chronic subordinate colony housing paradigm: A mouse model for mechanisms of PTSD vulnerability, targeted prevention, and treatment-2016 Curt Richter Award Paper.
There is considerable individual variability in vulnerability for developing posttraumatic stress disorder (PTSD); evidence suggests that this variability is related in part to genetic and environmental factors, including adverse early life experience. Interestingly, recent studies indicate that induction of chronic low-grade inflammation may be a common mechanism underlying gene and environment interactions that increase the risk for development of PTSD symptoms, and, therefore, may be a target for novel interventions for prevention or treatment of PTSD. Development of murine models with face, construct, and predictive validity would provide opportunities to investigate in detail complex genetic, environmental, endocrine, and immunologic factors that determine vulnerability to PTSD-like syndromes, and furthermore may provide mechanistic insight leading to development of novel interventions for both prevention and treatment of PTSD symptoms. Here we describe the potential use of the chronic subordinate colony housing (CSC) paradigm in mice as an adequate animal model for development of a PTSD-like syndrome and describe recent studies that suggest novel interventions for the prevention and treatment of PTSD.
