Physiology Seminar: Sex-specific brain and gut barrier alterations underlie stress vulnerability vs resilience in mice and human depression

Friday, January 13, 2023 11:00to12:00
McIntyre Medical Building room 1034, 3655 promenade Sir William Osler, Montreal, QC, H3G 1Y6, CA


Our research program aims to shed light on the biological mechanisms underlying stress vulnerability vs resilience, with help of state-of-the-art photonic technology, in order to develop innovative treatments and identify biomarkers of mood disorders. Our multidisciplinary approach combines behavioral experiments to functional, cellular, molecular, and imaging studies and validation of our rodent findings in human samples. We showed that chronic stress exposure promotes blood-brain barrier hyperpermeability leading to passage of circulating inflammatory mediators into the brain and the establishment of depressive behaviors. These changes occur in a sex-specific manner which may contribute to sex differences in depression prevalence, symptoms and treatment responses.


This seminar will take place both in-person and online. Details in attached poster
