    Abstract:
    The nonapeptides oxytocin (OXT) and arginine vasopressin (AVP) are two key mediators in regulating various aspects of mammalian social behaviours. There are several lines of evidence that genetic variants of the OXT/AVP system exist in autism spectrum disorder (ASD) and that this system is dysfunctional at least in some ASD entities. These findings have stimulated the interest to perform studies testing the potential therapeutic application of OXT/AVP in ASD. In this respect animal models are critical for investigating the pathophysiology and for compound screening leading to new therapeutic approaches. Based on findings in animal models that show alterations of the OXT/AVP system, it has been hypothesised that single- or multiple-dose administration or the stimulation of endogenous release can improve several social deficits. Here we comprehensively review the role of the OXT/AVP system in social recognition, social interaction and maternal behaviour in the light of different ASD animal models and patient studies. We further discuss implications for OXT/AVP-related pharmacological interventions to alleviate social deficits in ASD in the future.
