Neural cell adhesion molecule L1, discovered in the 80s, is one of the matters that can promote nerve regeneration. It can mediate the interaction of cell-to-cell and cell-to-matrix, take great efforts on neurite outgrowth and fasciculation, migration of neural cells, formation of the myelin, structure of neural trace, transmembrane signal transduction, inhibiting apoptosis of neural cells, even on immune system and formation of the tumor. Li is discovered on the mouse's Cerebellar membrane primarily. Thereafter, it also is found in post- mitotic neurons, pre- and non-myelinating Schwann cells and so on.

神经细胞粘附分子L1（L1）是80年代发现的具有促进神经再生作用的物质，它能介导神经细胞与神经细胞之间的粘附，在神经轴突的生长、聚集，神经细胞的转移，纤维髓鞘的形成，神经通路的构建及信号的转导，抑制神经细胞的凋亡甚至在免疫系统、肿瘤的发生等方面均具有非常重要的作用。L1最初是从小鼠的小脑膜中发现，后来发现在有丝分裂后的神经元，髓鞘形成前及非形成髓鞘的雪旺细胞等组织中同样存在。
