1080-果蝇大脑性别二态性的神经元存活与发育轴

from 聊聊Sci

这篇文章通过高分辨率单细胞转录组图谱,系统性地揭示了成年果蝇大脑中的性别差异。研究人员发现,神经系统的性别二态性主要受Doublesex (Dsx)和Fruitless (Fru)这两种转录因子驱动,而非大规模的转录重编程。通过将分子图谱与解剖特征结合,研究揭示了出生顺序是决定性差异的关键因素,其中雌性倾向于早期产生的神经元存活,而雄性则偏向于晚期。这一发现挑战了传统的性别分化模型,表明性二态神经元更多表现为发育窗口的偏移,而非简单的对应关系。该研究为理解行为回路在演化过程中的多样性提供了全新的框架和遗传工具包。References:Allen A M, Neville M C, Nojima T, et al.
