NgR has emerged as a focal point of convergence for mediating growth-inhibitory activities.

NgR是中枢神经元细胞膜上的一种蛋白，该蛋白和p75NTR及LINGO-1这两种中枢神经元细胞膜蛋白组成复合受体，介导了中枢神经系统髓磷脂中MAG、OMgp、Nogo对中枢神经元轴突生长的抑制作用，从而造成了成年哺乳动物中枢神经损伤后再生困难。

Although wolves dig under it, and roe deer and elk are believed to leap it, the herd of these largest of Europe's mammals remains divided, and with it, its gene pool—divided and mortally diminished, some zoologists fear.

尽管狼在地下打洞，人们也认为狍子和麋鹿能够越过这个障碍，但这个欧洲最大的哺乳动物群落还是被人为分隔开来，有些动物学家担心种群的遗传基因会遭到割裂，导致灭绝。

Barak makes most of her income by showing off her plants, which eat everything from insects and reptiles to small mammals and schnitzel.
