Sex is a key modifier of neurological disease outcomes. Microglia are implicated in neurological diseases and modulated by microRNAs, but it is unknown whether microglial microRNAs have sex-specific influences on disease. We show in mice that microglial microRNA expression differs in males and females and that loss of microRNAs leads to sex-specific changes in the microglial transcriptome and tau pathology. These findings suggest that microglial microRNAs influence tau pathogenesis in a sex-specific manner.

小胶质细胞microRNA介导对tau病理的性别特异性反应。

性别是神经系统疾病预后的关键调节因素。小胶质细胞与神经系统疾病有关,并受microRNA调控,但尚不清楚小胶质细胞microRNA是否对疾病具有性别特异性的影响。我们在小鼠中显示,小胶质细胞microRNA的表达在雄性和雌性中有所不同,并且microRNA的缺失会导致小胶质细胞转录组和tau病理学中的性别特异性变化。这些发现表明,小胶质细胞microRNA以性别特异性的方式影响tau发病机理。
