碱性成纤维细胞生长因子促神经再生的研究进展(2)

成周围神经,神经损伤的性质是细胞损伤。损伤后不仅轴突断裂,还引起近端神经元坏死,远段神经变性,失神经支配的感觉、运动效应器退变萎缩,因此神经损伤不仅是损伤局部一个水平有病变,还包括神经元、效应器,是三个水平的病变,只注重损伤局部的处理是片面的。成功的神经再生要求:(1)保护近端神经元;(2)再生轴突快速、准确长向远段;(3)效应器未发生不可逆性退变;(4)再生轴突与效应器形成功能性突触。SC、基底膜和神经营养因子(Neurotrophic Factor,NTF)是发挥以上作用的物质要素。NTF是指能保护神经元,和/或促进轴突再生的物质,已提出NGF、睫状神经节营养因子(CNTF)、脑源性营养因子(BDNF)、bFGF等20余种。至今,NGF由于:(1)体内有特异受体;(2)体内外作用均有效;(3)制备的抗体能阻断活性,唯一得到证实,而bFGF及其受体在周围神经的表达及损伤后变化的研究正在开展,其在体运用的效能、抗体阻断的实验亦待进行,所以是一种潜在的、未完全证实的NTF,但在试验中已经展现了较NGF促神经再生活性广泛的特点,除与NGF一样能保护神经元、促进轴突生长外,还能刺激SC增殖,促进毛细血管形成改善损伤神经及周围组织的血供,因而又是很有潜力的,预计随着以上两方面研究的进展,bFGF作为一种NTF的性质将很快澄清,为神经损伤患者带来新的希望。
