脑-肠轴视角下母源因素影响子代孤独症谱系障碍患病风险的研究进展
Research progress on maternal factors influencing the risk of autism spectrum disorder in offspring from a gut-brain axis perspective
孤独症谱系障碍(autism spectrum disorder, ASD)是一类以社会交往障碍和重复刻板行为为核心特征的神经发育性障碍。母体孕期环境因素被认为是子代ASD发生的重要危险因素,其机制涉及母体与子代肠道菌群紊乱、免疫失调、代谢异常及神经炎症等。特定益生菌干预通过调节肠道菌群结构、改善肠道屏障功能以及调控炎症反应和神经信号通路,在孕期及生命早期展现出预防与改善ASD的潜力。该文从脑-肠轴视角系统综述母源因素影响子代ASD风险的相关机制及潜在干预策略,以期为ASD的早期预防与干预提供理论依据和新的研究思路。
Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by core features of social communication deficits and repetitive, stereotyped behaviors. Maternal environmental factors during pregnancy are considered important risk factors for ASD in offspring, with mechanisms involving dysbiosis of the maternal and offspring gut microbiota, immune dysregulation, metabolic abnormalities, and neuroinflammation. Specific probiotic interventions show potential during pregnancy and early life to prevent and ameliorate ASD by modulating gut microbiota composition, improving intestinal barrier function, and regulating inflammatory responses and neural signaling pathways. This review systematically summarizes, from a gut-brain axis perspective, the mechanisms by which maternal factors influence ASD risk in offspring and the potential intervention strategies, aiming to provide a theoretical basis and new research directions for the early prevention and intervention of ASD.
