摘要: 生命早期社会环境会对人类个体身心健康产生持久的影响已久为人知, 然而要了解生命早期经历(包括来自母亲的关爱行为)与一生的认知和情绪健康之间的因果关系却只能借助于动物模型。文章综述了大鼠母爱行为对子代成年后应对应激的行为和繁育行为的影响及其表观遗传机制, 并就这一模型对于环境因素影响人类身心健康的研究所具有的意义进行了展望。

Abstract: It has been demonstrated that the social environment early in life has a long lasting effect on the physical and psychological health of the human body. However, understanding of the relationship between early life experiences, such as maternal care behavior, and life-long cognitive and emotional health can only rely on the studies on animal models. In this paper, we summarized the maternal care effects on both defensive responses to stress and reproductive behavior in rat, and explored the possible underling epigenetic mechanisms for these effects. Based on this model, we further investigated the significance of such epigenetic effects on human mental health.

Key words: maternal care, early life adversity, environmental programming, epigenetics
