概括

与多发性硬化症相关的膀失禁发生在脱髓化时. 令人惊的是,即使在复髓化失败时,膀功能也得到改善,这表明适应机制恢复了控制.

科学领域:

神经科学是一个神经科学.
泌尿器科泌尿器科泌尿器科泌尿器科
脱线性疾病脱线性疾病

背景情况:

膀功能障碍是多发性硬化症 (MS) 的常见并降低生活质量的并发症.
中枢神经系统 (CNS) 脱髓化与失禁有关,而复髓化有可能恢复膀控制.

研究的目的:

为了调查复髓化是否对于在急性脱髓化后恢复膀功能至关重要.
检查髓调节因子 (Myrf) 在复髓化和膀控制恢复中的作用.

主要方法:

使用了一种小鼠模型,在寡头细胞前体细胞 (OPC) 中条件淘汰了Myrf.
在脱髓化和复髓化阶段,使用cuprizone诱导脱髓化,并观察膀功能.
在Myrf-cKO小鼠和对照组中比较膀空气行为.

主要成果:

在所有小鼠中,无论基因型如何,急性脱髓化导致了明显的膀控制功能障碍 (增加排泄).
在复髓化阶段,所有群体的失禁改善,包括那些失败复髓化 (Myrf-cKO小鼠).

结论:

在多发性硬化模型中,活性脱髓化启动了膀功能障碍.
失败的复髓化并不能阻止能恢复膀功能的适应性变化,这表明了替代的恢复途径.

Neurogenesis and Regeneration of Nervous Tissue

Neurogenesis and Regeneration of Nervous Tissue

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...
