Deficits de récompense, GPCRs et sociabilité (DRuGS)

Our research is structured around three main axes:

 

 1: To identify the neural and molecular substrates involved in the control of social behaviour and, in pathological conditions, in the etiology of Autism Spectrum Disorders (ASD),

 

 2: To propose new pharmacological and/or behavioural approaches to facilitate or restore sociability, in a physiological or pathological context (autism),

 

3: To develop new pharmacological tools, in particular in the form of single-chain antibodies or nanobodies, targeting GPCRs of interest to understand their role in the control of social behaviour and/or to treat autistic symptoms.
