概括

神经带 (NT) 为小神经修复提供了无解决方案,其功能恢复和神经再生与老鼠坐骨神经模型中的传统微 (MS) 技术相当.

科学领域:

神经外科
复原医学
生物材料

背景情况:

微剪切 (MS) 神经损伤是目前小神经修复的标准,但存在技术挑战,导致功能恢复不足.
神经带 (NT) 是一种新型无装置,旨在简单精确地捕获神经.
这项研究评估了NT在1毫米老鼠坐骨神经模型上的疗效,模拟了数字和小感觉神经的修复.

研究的目的:

使用神经带 (NT) 与传统微 (MS) 技术进行神经修复的功能和组织学结果进行比较.
评估NT作为更简单,更精确的小直径神经修复替代品的潜力.

主要方法:

二十四只老鼠使用NT (n=12) 或MS (n=12) 进行了坐骨神经切割和修复.
结果包括坐骨功能指数,肌肉形态 (周围和质量比),肌肉收缩力和神经组织形态测量 (轴突数,g比).

主要成果:

在修复后3个月,NT在所有受试者中保持了设备的完整性.
在NT和MS群体中,肌肉周长和质量比率相似 (80.7%与80.9%和62.4%与58.4%).
肌肉收缩力,坐骨功能指数和远端轴突数在NT和MS组之间是相似的,表明神经再生和功能恢复相似.

结论:

神经带 (NT) 与传统的微 (MS) 神经损伤相比,实现了类似的神经再生和功能结果.
NT为小神经修复提供了一个可行的无替代方案,有可能简化手术并改善结果.

Ligand-gated Ion Channels

Ligand-gated Ion Channels

Ligand-gated ion channels are transmembrane proteins with a channel for ions to pass through and a binding site for a ligand. The channel opens only when a ligand attaches to the binding site.
Three Subfamilies of Ligand-gated Ion Channels
Ligand-gated ion channels fall into three subfamilies. The 'Cys-loop' includes the nicotinic acetylcholine receptors, γ-aminobutyric acid (GABA), glycine, and 5-hydroxytryptamine receptors. The second one is the 'Pore-loop' channels that...

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...
