Early-life exposure to stressful experiences has been described as a predisposing factor to develop psychopathologies including anxiety and depression. In our lab, we outlined a paradigm of unpredictable stress in C57BL/6 mice that aims to model exposure to fearful experiences during childhood and puberty. We observed that stressed animals present increased anxiety, depression-like behaviors and decreased sociability. Aiming at understanding the neuronal mechanisms whereby early life stress can induce these behavioral alterations, we performed a gene expression analysis in the nucleus accumbens, a critical brain region for the stress response. Remarkably, we observed that the nucleus accumbens of stressed animals exhibits a reduced expression of master-regulators of mitochondrial function such as SIRT1 and PGC-1a, concomitant with a reduction in mitochondrial respiration measured by high-resolution respirometry. These findings might pave the way for the use of mitochondrial boosters to treat stress-related disorders such as depression.
