Research group description

The aim is to find early molecular mechanisms that establish in the brain after chronic stress and which can then lead to a resilient behaviour. These early molecular mechanisms include epigenetic modification of chromatin, expression of non-coding RNAs, transcriptional changes in response to chronic stress but also changes in protein translation. We focus in particular on mechanisms caused by chronic defeat stress on the one hand and early life stress on the other. We use different mouse models, such as the Riboteq or the sun-GFP mouse, which help us to detect and characterize cell-specific changes. RNA sequencing, bi-sulfite sequencing, ATAC sequencing, and mass spectrometry are part of our methodological spectrum. In addition, epigenetic modulators and inhibitors of the mTOR kinase are used to influence resilient behavior. Furthermore, we are investigating in human cortical organoids the change of X inactivation during brain development as a possible modulator of behaviour.
