淀粉样前体蛋白胞内结构域对阿尔茨海默病模型小鼠神经发生和学习记忆的影响
Zhongshan Daxue xuebao. Yixue kexue ban目的探讨淀粉样前体蛋白胞内结构域（AICD）对阿尔茨海默病（AD）模型动物神经发生、学习记忆的影响。方法本研究使用免疫荧光染色检测AICD转基因小鼠来源的体外培养的神经前体细胞（NPCs）、胚胎大脑皮质、成年海马齿状回（DG）中增殖和分化的细胞数目；水迷宫实验检测老年AICD转基因小鼠对学习记忆能力影响；生物信息学预测和分析潜在的分子机制。结果免疫荧光染色结果显示AICD转基因模型体外NPCs、胚胎皮质、海马DG区域的神经干细胞和神经元数量减少（P < 0.05 ...

记忆辨别力是对相似的记忆经验进行准确辨别的能力,其依赖于名为模式分离的神经计算机制,在人类被试中,通常使用记忆相似性任务对其进行测量与研究。在老化过程中,老年人的记忆辨别力会出现十分明显的衰退,这种衰退与海马、内嗅皮层等内侧颞叶脑区的结构和功能衰退以及其他新皮层结构和功能老化关系密切。由于记忆辨别力高度依赖于内侧颞叶的结构和功能完整性,因此,它能够反映出认知障碍发展早期的异常脑结构和功能变化,使得记忆相似性任务具备了应用于认知障碍早期识别的巨大潜力 ...
