与身体中的大多数其他组织相比 ,中枢神经系统中的细胞几乎没有自我修复的能力。研究发现 ,神经轴突周围的脂肪质髓磷脂壳层可抑制神经细胞再生。这一结果促使人们去寻找与髓磷脂有关的可能的生长机制。三个研究小组在小鼠和人类身上发现了此前尚不为人们所知的一种基因 ,名叫? Compared to most other tissues in the body, cells in the central nervous system have almost no ability to repair themselves. The study found that the axon around the fat myelin sheath can inhibit nerve cell regeneration. This result prompted people to look for possible growth mechanisms associated with myelin. Three research groups found a previously unknown gene in mice and humans, called?
