中枢神经系统(CNS)无明显的再生功能。这一观点已被人们普遍所接受。但是,几年前在围绕CNS 的髓鞘中发现了生长抑制蛋白,接着制备了小鼠抗该蛋白的抗体;并且在神经细胞的培养中证实,该抗体能够通过灭活抑制因子而促进神经的生长。最近,在活体内首次证实了抗体的这一效应。将大鼠的脊髓皮质通道切断,实验鼠给予特异性抗体,而对照鼠不给抗体或给予与神经生长无关的抗体。结果由于特异性抗体对天然生长抑制因子的灭活作用,实验鼠受损部位有大量的神经纤维生长,三周内长达11mm;而 Central nervous system (CNS) no obvious regenerative function. This view has been generally accepted. However, growth inhibitory proteins were found in the myelin around the CNS several years ago, followed by the preparation of mouse anti-mouse antibodies against this protein; and in the culture of nerve cells, it was demonstrated that this antibody can promote neurogenesis by inactivating the inhibitory factor Grow. Recently, this effect of antibodies was first confirmed in vivo. The rat spinal cord cortex was cut off, the mice were given the specific antibody, and the control mice were given no antibody or given antibodies not related to nerve growth. Results Due to the inactivation of natural growth inhibitory factor by specific antibodies, a large number of nerve fiber growths were found in damaged parts of the experimental mice, up to 11 mm in three weeks
