尽管诸如自闭症谱系障碍、精神分裂症和双相情感障碍等精神疾病会影响多个脑区,并产生一系列复杂的临床症状,但基本表型可能在单个神经元和简单网络层面存在。由于这些疾病具有高度遗传性,据推测它们适合进行体外基于细胞的研究。利用诱导多能干细胞衍生的神经元和/或来自成纤维细胞的诱导神经元,现在可以从具有致病基因背景的患者身上产生无数的活人神经元。我们预测,基于细胞的研究最终将有助于我们对这些精神疾病的发病、进展和治疗的理解。
Although psychiatric disorders such as autism spectrum disorders, schizophrenia and bipolar disorder affect a number of brain regions and produce a complex array of clinical symptoms, basic phenotypes likely exist at the level of single neurons and simple networks. Being highly heritable, it is hypothesized that these disorders are amenable to cell-based studies in vitro. Using induced pluripotent stem cell-derived neurons and/or induced neurons from fibroblasts, limitless numbers of live human neurons can now be generated from patients with a genetic background permissive to the disease state. We predict that cell-based studies will ultimately contribute to our understanding of the initiation, progression and treatment of these psychiatric disorders.
