美国麻省理工学院和哈佛大学广泛研究所Michal SchwartzAviv RegevNaomi Habib研究组合作取得新进展。他们发现阿尔茨海默氏病和衰老过程中与疾病相关的星形胶质细胞。该研究于20204月27日发表在《自然-神经科学》杂志上。

他们利用单核RNA测序技术,在阿尔茨海默氏病小鼠模型中鉴定出与疾病相关的星形胶质细胞群。这些与疾病相关的星形胶质细胞出现在疾病的早期阶段,并随着疾病进展而增加。他们发现类似的星形胶质细胞出现在衰老的野生型小鼠和衰老的人脑中,表明它们与遗传和年龄相关因素有关。

据了解,非神经细胞在阿尔茨海默氏病进展中的作用尚未完全阐明。

Abstract: The role of non-neuronal cells in Alzheimer’s disease progression has not been fully elucidated. Using single-nucleus RNA sequencing, we identified a population of disease-associated astrocytes in an Alzheimer’s disease mouse model. These disease-associated astrocytes appeared at early disease stages and increased in abundance with disease progression. We discovered that similar astrocytes appeared in aged wild-type mice and in aging human brains, suggesting their linkage to genetic and age-related factors.
