1322-人类伏隔核空间转录组图谱

from 聊聊Sci

该研究通过整合单细胞核转录组学与空间转录组学技术,构建了人类伏隔核(NAc)的首个高分辨率时空分子图谱。研究人员识别出20种独特的细胞群体,证实了中等多棘神经元(MSN)亚型在空间上呈连续梯度分布,而非简单的离散边界。研究重点揭示了高度保守的D1岛状结构,其富含OPRM1基因并与阿片类药物反应及成瘾机制密切相关。通过跨物种分析,该图谱展示了人类与啮齿类及非人灵长类在伏隔核构造上的演化保守性。此外,该成果还预测了与神经精神疾病风险相关的配体-受体相互作用,为理解精神分裂症、抑郁症及药物滥用的分子病理提供了关键框架。References:Ravichandran P, Bach S V, Phillips R A, et al.
