Our Research

A05 will exploit natural inter-individual variability of resilience by comparing transcriptomes and genome-wide chromatin accessibility of hippocampus, nucleus accumbens and prefrontal cortex between resilient and non-resilient mice. Next, we will apply specific inhibitors of distinct epigenetic regulators to different groups of mice at the time of stress and compare their later behavioral outcomes with non-drug treated control groups subjected to identical stress. For mice treated with the inhibitor that showed the strongest resilience-promoting effects, we will then determine transcriptomes, genome-wide chromatin accessibility and associated epigenetic marks of the above mentioned brain regions.
