Introduction: Autism spectrum disorder (ASD) is a persistent neurodevelopmental condition characterized by two core behavioral symptoms: impaired social communication and interaction, as well as stereotypic, repetitive behavior. No distinct cause of ASD is known so far; however, excitatory/inhibitory imbalance and a disturbed serotoninergic transmission have been identified as prominent candidates responsible for ASD etiology.
Methods: The GABA receptor agonist R-Baclofen and the selective agonist for the 5HT serotonin receptor LP-211 have been reported to correct social deficits and repetitive behaviors in mouse models of ASD.
