摘要:

神经再生条件液是神经再生室模型中神经断端分泌的功能性液体,描绘其中的蛋白成分谱,可为研究微环境在周围神经再生中的作用提供直接依据。为此,实验使用硅材料构成的圆筒状神经再生室修复大鼠损伤坐骨神经,蛋白质组学、iTRAQ蛋白组学定量分析及Western blot结果均显示神经再生条件液中存在10余种补体(补体因子I, C1q-A, C1q-B, C2, C3, C4, C5, C7, C8β和补体因子D),且各种补体都出现明显变化,也包括C1q,C3,C7和补体因子D。全部结果均证实,这些补体都与神经再生有关。

Abstract:

Nerve regeneration conditioned fluid is secreted by nerve stumps inside a nerve regeneration chamber. A better understanding of the proteinogram
of nerve regeneration conditioned fluid can provide evidence for studying the role of the microenvironment in peripheral nerve
regeneration. In this study, we used cylindrical silicone tubes as the nerve regeneration chamber model for the repair of injured rat sciatic
nerve. Isobaric tags for relative and absolute quantitation proteomics technology and western blot analysis confirmed that there were more
than 10 complement components (complement factor I, C1q-A, C1q-B, C2, C3, C4, C5, C7, C8β and complement factor D) in the nerve
regeneration conditioned fluid and each varied at different time points. These findings suggest that all these complement components have
a functional role in nerve regeneration.
