这篇讲什么
本文通过单核多组学测序揭示了唐氏综合征患者早期产后背外侧前额叶皮层中基因表达和染色质可及性的全局失调,包括神经元代谢和突触基因程序破坏、少突胶质细胞谱系进展受损以及神经炎症特征。

Sousa1,2* Down syndrome is a genetic condition that causes intellectual disability and is characterized by early-­onset delays in motor, cognitive, and language development. The molecular mechanisms underlying these neurodevelopmental impairments remain poorly understood. We used single-­nucleus multiomic sequencing to simultaneously profile gene expression and chromatin accessibility in the Down syndrome prefrontal cortex during early postnatal development, a critical period for synaptogenesis, neural maturation, and developmental neuroimmune interactions. …
