SUMMARY:Seminar - Julie Le Merrer
DESCRIPTION:Venue: Centre Broca \n\nJulie Le Merrer\nDR CNRS\nUniversité de Tours \nInvited by Jean-Luc Morel (INCIA) \nTitle\nSocial behavior and striatum: reward matters \nAbstract\nSocial interactions are experienced as pleasurable\, which in turn fuels social motivation. Consistent with this\, the so-called “social brain” widely overlaps with the brain reward circuit. Within this circuit\, the nucleus accumbens (NAc) works as a hub structure and plays a unique role in reward processing and approach. Accumulating evidence suggest that the NAc is a key substrate for modulating social behavior. However\, the respective contributions of the two main neuronal populations in the NAc\, Striatal Projection Neurons (SPNs)\, bearing either D1 or D2 dopamine receptors\, remains elusive. D1- and D2-SPNs play contrasted roles in modulating reward\, with the former proposed to drive pro-reward/approach responses and the latter considered as inhibiting these responses. We previously evidenced that chronic facilitation of mGlu4 glutamate receptor activity\, known to put a brake on D2-SPN activity\, relieves social deficit in the Oprm1 null mouse model of autism. Here we tested the hypothesis that excessive D2-SPN activity may compromise social reward. We first explored the respective roles of D1- and D2-SPN of the NAc in driving social behavior by selectively ablating each of these neuronal populations using an inducible diphtheria toxin receptor (DTR)-mediated cell targeting strategy. We then used pharmacological tools to rescue behavior in ablated mice and transcriptome analysis to assess striatal physiology. Finally\, we mimicked excessive NAc D2-SPN activation using optogenetics. This study allowed us to identify the respective roles of NAc D1- and D2-SPNs in driving social motivation\, with exciting perspectives for the treatment of pathologies such as autism\, schizophrenia or depression. \nKey publications\n\nMeng J\, Xu C\,Lafon P-A\, Roux S\, Mathieu M\, Scholler P\,  Blanc E\, Becker JAJ\, Le Merrer J\, Gonzales-Maeso J\, Chames P\, Liu J\, Pin J-P\, Rondard P.
