Our research seeks to uncover the underlying mechanisms of stress resilience. By understanding those mechanisms, we can employ them to develop better treatment strategies for stress related mental disorders and prevention. Our research has developed a new mouse model with high face validity that allows stratifying a single group of stressed mice into resilience and susceptibility associated phenotypes that are based on the fear circuitry.
Also, we provide evidence for the presence of global resilience mechanisms. Our study on stressed mice revealed that they exhibited characteristics that are indicative of both resilience and susceptibility in humans. Specifically, they show different abilities in threat safety discrimination and responsiveness to extinction, which are key features associated with resilience.
The resilience and susceptibility associated phenotypes that we identified in mice have face validity and are based on the fear circuitry. This circuitry is highly conserved across species and is arguably one of the best studied circuits. In turn, this allows mechanistic investigations that have the potential to contribute to treatment, development and prevention measures.
We'll use our new model to dig deeper into neurobiological mechanisms of resilience and understand how we can actively promote resilience. In addition, we will employ longitudinal analysis to decifer how individual resilience develops over time.
