    Project summary :

    Today, the mechanisms at the origin of the progressive loss of cognitive functions associated with Alzheimer's disease (AD) remain largely unknown. Our recent studies have shown a dysfunction of inhibitory parvalbumin (PV) interneurons in transgenic mouse models of the disease, as well as in AD patients. PV interneurons coordinate neuronal activity in the local network and throughout the brain, thus their activity is necessary for cognitive functions. In this context, the aim of my research project is to identify functional changes of PV interneurons in mouse models of AD which may induce memory deficits, and to establish new restoration strategies for memory functions in AD.
