概括
在儿科多发性硬化症 (MS) 中,内核层 (INL) 在视神经炎 (ON) 后变厚,不像其他视网膜层变薄. 在本研究中,INL厚度与疾病严重程度没有相关性.
科学领域:
- 眼科医生 眼科 眼科
- 神经科学是一个神经科学.
- 儿科神经学 儿科神经学
背景情况:
- 儿科发病多发性硬化症 (POMS) 导致视觉神经和视网膜损伤,包括周状视网膜神经纤维层 (pRNFL) 和黄斑结质细胞和内状层 (GCIP) 的稀薄.
- 内部核层 (INL) 厚度假设随着炎症或急性视神经炎 (ON) 后增加,并随着神经退行而减少.
- 在成年多发性硬化患者中观察到INL中的斑点微囊.
研究的目的:
- 在一大批儿科发病多发性硬化症 (POMS) 患者中研究内核层 (INL).
- 评估INL作为疾病过程和POMS治疗成功的潜在生物标志物.
- 为了将POMS的INL变化与有或没有视神经炎 (ON) 史的健康对照进行比较.
主要方法:
- 一项横截面病例控制研究,涉及153名POMS患者和92名对照患者.
- 潜在的参与者招募,包括无症状的健康志愿者和患有非视网膜疾病的儿童.
- 光学连贯断层扫描 (OCT) 带有网膜内细分和最佳校正视敏度 (BCVA) 评估.
主要成果:
- 与POMS和之前的ON眼睛的眼睛显示,与对照 (42.96μm,p=0.014) 相比,INL厚度增加 (44.31μm).
- 与对照组 (pRNFL 97 微米,GCIP 78.53 微米) 相比,在之前有ON的POMS眼中,pRNFL (83 微米) 和GCIP厚度 (68.42 微米) 降低了.
- 与对照组相比,在没有ON病史的POMS眼睛中没有发现INL或其他层厚度的显著差异. pRNFL和GCIP损失与较差的BCVA相关,但INL厚度没有.
结论:
- 在POMS中,INL表现出与成年MS相似的变化,尽管黄斑微囊相当罕见.
- 在INL厚度和疾病严重程度之间没有横截面关联,这表明早期疾病中神经炎症占主导地位,而不是神经退行.
- 需要进一步的纵向研究来澄清INL变化作为POMS生物标志物的作用.

01:25Nervous Tissue: Myelin
2.2K
The myelin sheath is a multilayered lipid and protein covering that insulates the axon of a neuron, enhancing the speed of nerve impulse conduction. Axons without this sheath are referred to as unmyelinated. Two types of neuroglia, Schwann cells in the peripheral nervous system (PNS) and oligodendrocytes in the central nervous system (CNS) are responsible for producing myelin sheaths.
Schwann cells begin to form myelin sheaths around axons during fetal development. They wrap around a small...

01:15Neurogenesis and Regeneration of Nervous Tissue
685
In the CNS, neurogenesis, the birth of new neurons from stem cells, is limited to the hippocampus in adults. In other regions of the brain and spinal cord, neurogenesis is almost non-existent due to inhibitory influences from neuroglia, especially oligodendrocytes, and the absence of growth-stimulating cues. The myelin produced by oligodendrocytes in the CNS inhibits neuronal regeneration. Furthermore, astrocytes proliferate rapidly after neuronal damage, forming scar tissue that physically...
