Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterised by repetitive behaviours, cognitive rigidity/inflexibility, and social-affective impairment. Unfortunately, few pharmacological treatments exist to alleviate these socio-behavioural impairments. Prenatal administration of valproic acid (VPA) has become an accepted animal model of ASD and has been extensively used to explore new pharmacotherapies in rodents. We conducted a systematic review of the behavioural impairments induced by the VPA model in rodents, with specific reference to 3 core socio-behavioural alterations associated with ASD: repetitive behaviours, cognitive rigidity/inflexibility, and social-affective impairment. We systematically reviewed studies attempting to alleviate these core behavioural alterations using pharmacological means. We include 132 studies exploring the prenatal effects of VPA in rodents. Gestational exposure to VPA in rodents has significant effects on rodent-equivalent measures of the 3 core behavioural traits characteristic of ASD in humans, inducing social impairments, repetitive behaviour, and cognitive rigidity/inflexibility after birth. This model’s validity has seen it used to test potential drug treatments for ASD and is likely to continue doing so. We conclude the rodent VPA model may be suitable to examine future therapeutic interventions for ASD, providing an overview of the progress made so far.

对丙戊酸诱导的自闭症啮齿动物模型的系统评价。

自闭症谱系障碍 (ASD) 是一种神经发育障碍,其特征是重复行为、认知僵化/僵化和社交情感障碍。不幸的是,几乎没有药物治疗可以减轻这些社会行为障碍。丙戊酸 (VPA) 的产前给药已成为公认的 ASD 动物模型,并已广泛用于探索啮齿动物的新药物疗法。我们对 VPA 模型在啮齿动物中引起的行为障碍进行了系统审查,特别参考了与 ASD 相关的 3 个核心社会行为改变:重复行为、认知僵化/僵化和社会情感障碍。我们系统地回顾了试图使用药理学手段减轻这些核心行为改变的研究。我们纳入了 132 项探索 VPA 对啮齿动物产前影响的研究。啮齿动物妊娠期暴露于 VPA 对人类 ASD 的 3 个核心行为特征的啮齿动物等效测量具有显着影响,导致社交障碍、重复行为和出生后认知僵化/僵化。该模型的有效性已经证明它用于测试 ASD 的潜在药物治疗,并且可能会继续这样做。我们得出结论,啮齿动物 VPA 模型可能适用于检查 ASD 未来的治疗干预,提供迄今为止取得的进展的概述。重复行为,以及出生后的认知僵化/僵化。该模型的有效性已经证明它用于测试 ASD 的潜在药物治疗,并且可能会继续这样做。我们得出结论,啮齿动物 VPA 模型可能适用于检查 ASD 未来的治疗干预,提供迄今为止取得的进展的概述。重复行为,以及出生后的认知僵化/僵化。该模型的有效性已使其用于测试 ASD 的潜在药物治疗,并且可能会继续这样做。我们得出结论,啮齿动物 VPA 模型可能适用于检查 ASD 未来的治疗干预,提供迄今为止取得的进展的概述。
