概括
这项研究详细介绍了胎儿全脑发育 (HPE) 中的白质病理,在大多数情况下发现了周周结节性白血病样变化和异常通道. 遗传分析揭示了一些潜在的原因,但这种大脑形的统一病因仍然难以捉摸.
科学领域:
- 神经科学是一个神经科学.
- 发展生物学 发展生物学
- 病理学 病理学 病理学
背景情况:
- 整体大脑缺陷 (HPE) 是一种先天性大脑形,其特征是前脑分裂失败.
- 在HPE中,白质异常很少被记录下来,对其病变的理解有限.
- 扩散张力成像表明HPE中的白质结构混乱,需要进一步调查.
研究的目的:
- 描述胎儿HPE病例与白质病理学的临床病理学和分子特征.
- 调查一系列HPE胎儿白质异常的性质和程度.
- 为了确定与HPE和并发白质发现相关的潜在遗传病因.
主要方法:
- 对8例胎儿HPE病例进行了基于尸检的临床病理学检查.
- 对周周结膜性白血病 (PVL) 类变化和异常白质道的组织病理学分析.
- 下一代测序 (NGS) 专家小组专注于HPE相关基因.
主要成果:
- 所有8例病例都显示出类似PVL的白质病理.
- 七个病例表现出异常的白质道,其中一个形成了明显的中线捆绑.
- 基因分析在4个病例中发现了可能的病因,在另外2个病例中发现了未知意义的变异.
结论:
- 胎儿HPE经常呈现出类似PVL的白质病理和异常通道.
- 异常的白质道可能存在类似PVL的病变.
- 虽然遗传因素有关,但没有确定HPE与这种特定白质模式的统一病因.

1.8K
The cross-sectional anatomy of the spinal cord offers a detailed view of its complex structure and function within the central nervous system. At the core of the spinal cord lies the gray matter, characterized by its butterfly or "H"-shaped appearance in cross-section. This central region is enveloped by white matter, with the overall structure divided into symmetrical halves by the dorsal median sulcus and the ventral median fissure.

41.8K
Neurulation is the embryological process which forms the precursors of the central nervous system and occurs after gastrulation has established the three primary cell layers of the embryo: ectoderm, mesoderm, and endoderm. In humans, the majority of this system is formed via primary neurulation, in which the central portion of the ectoderm—originally appearing as a flat sheet of cells—folds upwards and inwards, sealing off to form a hollow neural tube. As development proceeds, the...
