概括

通过皮肤的迷走神经刺激 (t-VNS) 在脊髓损伤 (SCI) 后没有显著改变巨细胞分布. 然而,趋势表明t-VNS可能会降低M1巨细胞的激活,表明潜在的抗炎作用.

科学领域:

神经科学是一个神经科学.
免疫学免疫学免疫学
再生医学是一种再生医学.

背景情况:

脊髓损伤 (SCI) 是由创伤造成的,缺乏治愈治疗.
皮炎包括初级机械损伤和二次炎症反应,导致细胞死亡.
缓解神经炎症对于治疗二次性SCI至关重要,迷走神经刺激 (VNS) 是一种潜在的模式.

研究的目的:

调查穿皮VNS (t-VNS) 对SCI后的炎症过程的影响.
评估t-VNS对大细胞种群在老鼠SCI伤模型中的影响.

主要方法:

在雄性Sprague-Dawley大鼠中建立了脊髓损伤 (SCI) 伤模型.
组织病理学分析比较了接受t-VNS和对照组的老鼠之间的巨细胞群 (M1,M2a,M2b,M2c).

主要成果:

在t-VNS和对照组之间没有观察到M1,M2a,M2b或M2c巨细胞水平的统计学上显著差异 (p>0.27).
后期分析显示,在t-VNS组 (斯皮尔曼r = -0.50) 中,随着时间的推移,M1巨细胞的下降速度更快.

结论:

通过皮肤进行的VNS并没有显著改变SCI后的总体巨细胞分布.
观察到的减少M1巨细胞激活的趋势表明,在SCI的背景下,t-VNS的潜在抗炎作用.

关键词:

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...
