Müller; Günter Schumann; Hiroyuki Okuno; Kasia Radwańska;Le trouble de la consommation d'alcool (AUD) est une maladie chronique et mortelle. Le principal obstacle au traitement par AUD est une forte probabilité de rechute à l'abus d'alcool, même après une abstinence prolongée. Les mécanismes moléculaires de la rechute induite par les signaux ne sont pas bien établis, malgré le fait qu'ils peuvent offrir de nouvelles cibles pour le traitement de l'AUD. En utilisant un modèle animal complet d'AUD, des manipulations génétiques à médiation virale et ciblées sur l'amygdale par la technologie CRISPR/Cas9 et l'électrophysiologie ex vivo, nous identifions un mécanisme qui contrôle sélectivement la rechute d'alcool induite par les signaux et la gravité des symptômes d'AUD. Ce mécanisme est basé sur l'activité régulée de la protéine associée au cytosquelette (ARC)/plasticité dépendante de l'Arg3.1 des synapses de l'amygdale. Chez l'homme, nous avons identifié des polymorphismes mononucléotidiques dans le gène ARC et leur méthylation prédisant non seulement la taille de l'amygdale, mais aussi la fréquence de la consommation d'alcool, même au début de la consommation régulière. Cibler l'arc pendant l'exposition à l'alcool peut donc être un nouveau mécanisme sélectif pour la prévention des rechutes. El trastorno por consumo de alcohol (TCA) es una enfermedad crónica y mortal. El principal impedimento de la terapia AUD es una alta probabilidad de recaída en el abuso de alcohol incluso después de una abstinencia prolongada. Los mecanismos moleculares de la recaída inducida por señales no están bien establecidos, a pesar de que pueden ofrecer nuevas dianas para el tratamiento de la AUD. Utilizando un modelo animal integral de AUD, manipulaciones genéticas mediadas por virus y dirigidas a la amígdala mediante tecnología CRISPR/Cas9 y electrofisiología ex vivo, identificamos un mecanismo que controla selectivamente la recaída de alcohol inducida por señales y la gravedad de los síntomas de AUD. Este mecanismo se basa en la actividad regulada de la proteína asociada al citoesqueleto (ARC)/plasticidad dependiente de Arg3.1 de las sinapsis de la amígdala. En humanos, identificamos polimorfismos de un solo nucleótido en el gen ARC y su metilación prediciendo no solo el tamaño de la amígdala, sino también la frecuencia del consumo de alcohol, incluso al inicio del consumo regular. Dirigirse a Arc durante la exposición al alcohol puede ser, por lo tanto, un nuevo mecanismo selectivo para la prevención de recaídas. Alcohol use disorder (AUD) is a chronic and fatal disease. The main impediment of the AUD therapy is a high probability of relapse to alcohol abuse even after prolonged abstinence. The molecular mechanisms of cue-induced relapse are not well established, despite the fact that they may offer new targets for the treatment of AUD. Using a comprehensive animal model of AUD, virally-mediated and amygdala-targeted genetic manipulations by CRISPR/Cas9 technology and ex vivo electrophysiology, we identify a mechanism that selectively controls cue-induced alcohol relapse and AUD symptom severity. This mechanism is based on activity-regulated cytoskeleton-associated protein (Arc)/ARG3.1-dependent plasticity of the amygdala synapses. In humans, we identified single nucleotide polymorphisms in the ARC gene and their methylation predicting not only amygdala size, but also frequency of alcohol use, even at the onset of regular consumption. Targeting Arc during alcohol cue exposure may thus be a selective new mechanism for relapse prevention. Alcohol use disorder (AUD) is a chronic and fatal disease.
