1106-人造杏仁核类器官及其应激回路模型

from 聊聊Sci

这项研究成功培育出人造杏仁核类脑器官(hATOs),精准模拟了人类杏仁核的细胞多样性与发育轨迹。科研人员通过将这种器官与下丘脑类器官结合,构建了能够模拟人类压力反应回路的组装体模型。实验证实,皮质醇暴露会诱发应激信号转导,并特异性上调一种灵长类动物特有的非编码RNA——BCYRN1。这种分子的异常表达会直接干扰突触功能,揭示了压力激素导致神经发育受损的分子机制。该系统为探索神经精神疾病的起源提供了高度仿生的实验平台。References:Yang W, Choe M, Lo C .Human amygdala-like telencephalic organoids model stress circuitry in assembloid systems.
