The reason is the tumor cells escape the immunosurveillance whose mechanism is very complex. In general, the explanation is based on two aspects, one is that the tumor cells can passively escape the host immunosurveillance when the host immnue state is low and another is tumor cells can actively secrete factors to down-regulate immune function.

肿瘤逃避免疫监视的机制非常复杂，但总体上可从宿主免疫状态及肿瘤细胞等方面来解释，在宿主免疫状态低下时，肿瘤细胞可以被动地逃避免疫监视，但是肿瘤细胞也能主动地释放一些活性物质，下调免疫杀瘤作用，该作用主要通过两个途径，即对免疫细胞功能的调节和免疫细胞数量的调节。

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。

Recent researches have shown that FOXP3(forkhead transcription facter3),which is a critical transcription factor in regulatory T cells development,plays a very important role in regulatory T cells development,This article gives an overview about molecule structure function,the relation of CD+4CD+25 Treg cells in development and function,and the meaning of clinical measure.
