Team Freddy JEANNETEAU

Stress hormones & plasticity

Freddy Jeanneteau
DR2, CNRS

ATIP-AVENIR team created in 2013, consolidated into Team-FRM in 2018 affiliated with the national network on autism and neurodevelopmental disorders, the network on neurodegenerative diseases, the Occitanie perinatal network and the international neurobiology of stress network.
Type of research: preclinical and translational
Our discoveries are qualified as scientific highlights by peer societies in 2016, 2018, 2019, 2021 and 2023.

We seek to identify mechanisms of brain plasticity to be diverted to correct neurological and psychiatric pathological trajectories. We apply this strategy on animal models and when possible, we involve clinicians to accelerate the transition to humans. For 10 years, our research has focused on the protective properties of neuropeptides (Oxytocin, Vasopressin, Somatostatin, BDNF, PDGF-BB) on the brain pushed to the limits of its plasticity in supra-physiological and pseudo-pathological conditions.
Today our research is focused on the fields of neuroprotection applied to the maintenance and construction of neural connectivity networks from birth to aging.

The funders are the ANR, the NIH, the foundation for medical research, FP7, Horizon Europe, France Alzheimer…
