尽管自闭症的临床和遗传异质性,大量基因表达研究表明,自闭症患者新皮层的变化集中在共同的基因和途径上。然而,直接评估受自闭症影响的大脑中的特定细胞类型直到最近才变得可行。我们使用单核RNA测序的皮质组织从自闭症患者,以确定自闭症相关的转录组的变化,在特定的细胞类型。我们发现,上层兴奋性神经元的突触信号和小胶质细胞的分子状态在自闭症中优先受到影响。此外,我们的研究结果表明,皮质-皮质投射神经元中特定基因组的失调与自闭症的临床严重程度相关。这些发现表明,上层皮质回路的分子变化与自闭症的行为表现有关。
Despite the clinical and genetic heterogeneity of autism, bulk gene expression studies show that changes in the neocortex of autism patients converge on common genes and pathways. However, direct assessment of specific cell types in the brain affected by autism has not been feasible until recently. We used single-nucleus RNA sequencing of cortical tissue from patients with autism to identify autism-associated transcriptomic changes in specific cell types. We found that synaptic signaling of upper-layer excitatory neurons and the molecular state of microglia are preferentially affected in autism. Moreover, our results show that dysregulation of specific groups of genes in cortico-cortical projection neurons correlates with clinical severity of autism. These findings suggest that molecular changes in upper-layer cortical circuits are linked to behavioral manifestations of autism.
