精神分裂症和相关精神疾病的发病机制可能涉及影响小的易感基因和环境因素之间的多重相互作用。基因-环境相互作用发生在神经发育的不同阶段,从而产生疾病的异质性临床和病理表现。基因-环境相互作用机制研究的主要障碍是缺乏合适的实验系统来阐明介导与精神分裂症相关的基因-环境相互作用的分子途径。精神病遗传学的最新进展和大量的动物实验数据使我们能够提出一种新的方法来研究精神分裂症的基因-环境相互作用。我们建议,基于已确定的基因突变和可测量的环境因素的动物模型将有助于推进基因-环境相互作用的分子机制的研究。
The pathogenesis of schizophrenia and related mental illnesses likely involves multiple interactions between susceptibility genes of small effects and environmental factors. Gene-environment interactions occur across different stages of neurodevelopment to produce heterogeneous clinical and pathological manifestations of the disease. The main obstacle for mechanistic studies of gene-environment interplay has been the paucity of appropriate experimental systems for elucidating the molecular pathways that mediate gene-environment interactions relevant to schizophrenia. Recent advances in psychiatric genetics and a plethora of experimental data from animal studies allow us to suggest a new approach to gene-environment interactions in schizophrenia. We propose that animal models based on identified genetic mutations and measurable environment factors will help advance studies of the molecular mechanisms of gene-environment interplay.
