Animal Models of Stress Vulnerability and Resilience in Translational Research

Stress has been identified as a key risk factor for a multitude of human pathologies. However, stress by itself is often not sufficient to induce a disease, as a large contribution comes from an individual’s genetic background. Therefore, many stress models have been created to investigate this so-called gene–environment interaction for different diseases. Recently, evidence has been accumulating to indicate that not only the exposure to stress, but also the vulnerability to such an exposure can have a significant impact on the development of disease. Herein we review recent animal models of stress vulnerability and resilience, with special attention devoted to the readout parameters and the potential for translatability of the results.
