SUMMARY:PhD seminar - Paulo Pinheiro
DESCRIPTION:Venue: Centre Broca \nPhD seminars are open to everyone!  \n\nPaulo Pinheiro\nPrincipal Investigator\, Center for Neuroscience and Cell Biology\nAssistant Professor\, Department of Life Sciences\nUniversity of Coimbra \nPaulo Pinheiro was a post-doctoral researcher in Christophe Mulle’s team in 2006-2009. \nTitle\nChronic stress impacts synaptic transmission and network activity through miR-186-5p \nAbstract\nChronic stress has significant negative effects on cognitive and emotional behaviors and is a key risk factor for neuropsychiatric disorders. However\, the molecular mechanisms behind these effects remain unclear. Here\, we show that chronic stress triggers the upregulation of miR-186-5p\, which plays a central role in synaptic dysfunction. Increased miR-186-5p levels were observed in both the prefrontal cortex of stressed mice and neurons exposed to dexamethasone. Overexpression of miR-186-5p in mice induced anxiety- and depressive-like behaviors. This upregulation disrupts the balance between glutamatergic and GABAergic transmission and leads to altered network activity\, but can be normalized by a miR-186-5p inhibitor. Our work highlights a new link between chronic stress\, miR-186-5p expression\, and the synaptic changes underlying behavioral and cognitive dysfunction. \nSelected publications\n– Rodrigues\, B.\, Leitão\, R.A.\, Santos\, M. et al.
