DG-GCL基因表达图谱揭示精神分裂症内幕 - 科学网
2020年3月24日 · 在 DG-GCL 中鉴定出的约 900 万个表达定量性状基因座中,在海马体中 15% 未检测到,包括 15 个精神分裂症风险变异。 他们从 DG-GCL 创建了转录组范围的关联研究遗传权重,该遗传权重确定了大量海马体在转录组范围的关联研究中未发现的许多精神分裂症相关的遗传信号,包括 GRM3 和 CACNA1C。 这些结果凸显了有针对性的采样策略(如 LCM)和人脑中的完整匀浆和单核方法所提供的更高的生物分辨率。 据悉,特定的细胞群可能对精神分裂症有独特 …
The dentate gyrus: fundamental neuroanatomical organization …
The DG is divided into a molecular layer (ml) a granule cell layer (gcl) and a polymorphic layer (pl). The molecular layer is divided into three sublayers based on the laminar organization of inputs. The hippocampus is divided into CA3, CA2 and CA1 subfields.
Assessments of dentate gyrus function: discoveries and debates
2023年6月14日 · There has been considerable speculation regarding the function of the dentate gyrus (DG) — a subregion of the mammalian hippocampus — in learning and memory. In this Perspective article, we...
Nectin-3 modulates the structural plasticity of dentate ... - Nature
2017年9月5日 · To estimate the volume of the granule cell layer (GCL) of dorsal DG, images were captured at × 100 using a DP72 camera (Olympus) fitted to the microscope. The GCL was outlined and its area...
transcriptional landscape of the granule cell layer of the dentate gyrus (DG-GCL) in human hippocampus, and contrasted to homogenate tissue. We identified widespread cell type-specific aging and genetic effects in the DG-GCL that were either missing or directionally discordant in

在 dg-gcl 中鉴定的约 900 万个表达数量性状基因座中,15% 未在海马体中检测到,包括 15 种精神分裂症风险变异体。 我们从 DG-GCL 创建了全转录组关联研究遗传权重,GRM3和CACNA1C。
Spatial Representations of Granule Cells and Mossy Cells of the …
2017年2月8日 · The dentate gyrus (DG) is the only region of the hippocampus that contains two distinct, excitatory cell types. Granule cells, located in the densely packed granule cell layer (GCL), are by far the most numerous cell type in the DG (Amaral et al., 1990).
