摘要

简介成人大脑中的神经发生可能在记忆和认知中发挥重要作用;然而,人们对人脑中神经发生标记的了解仍然有限。我们比较了海马与其他皮层区域的单核转录组,以确定海马特异性神经源标记:我们分析了在人死亡后 16 小时内采集的四个人脑中的 26,189 个细胞核。我们进行了聚类和注释,以检查差异表达、基因本体和细胞间通讯。通过液滴 ddPCR 验证了 DCX 的表达:结果:DCX、CALB2、NES、SOX2、PAX6、DPYSL3 和 TUBB3 等未成熟标记物在海马和前额叶皮层均有表达,其中前额叶皮层的表达水平更高。DCX 参与了神经发生和神经保护途径:结论:神经源性标志物并不是成人神经发生的明确指标,因为它们的作用比以前所理解的更为复杂。

Reconsidering Neurogenetic Indication in the Human Brain: Broad Expression of Doublecortin Transcript in the Hippocampal and Cortical Cell Populations.

Introduction: Neurogenesis in the adult brain may play an important role in memory and cognition; however, knowledge of neurogenic markers in the human brain remains limited. We compared the single-nucleus transcriptome of the hippocampus with that of other cortical regions to identify hippocampus-specific neurogenic markers.

Methods: We analyzed 26,189 nuclei from four human brains collected within 16 h of death. Clustering and annotation were performed to examine differential expression, gene ontology, and intercellular communication. DCX expression was validated by ddPCR.

Results: Immature markers such as DCX, CALB2, NES, SOX2, PAX6, DPYSL3, and TUBB3 were expressed in both hippocampus and prefrontal cortex, with higher levels in the prefrontal cortex. ddPCR confirmed higher expression of DCX in the prefrontal cortex. DCX was involved in both neurogenesis and neuroprotection pathways.

Conclusion: Neurogenic markers are not definitive indicators of adult neurogenesis as their roles are more complex than previously understood.

期刊介绍: ''Cells Tissues Organs'' aims at bridging the gap between cell biology and developmental biology and the emerging fields of regenerative medicine (stem cell biology, tissue engineering, artificial organs, in vitro systems and transplantation biology). CTO offers a rapid and fair peer-review and exquisite reproduction quality. Special topic issues, entire issues of the journal devoted to a single research topic within the range of interests of the journal, are published at irregular intervals.
