Rabies Virus Glycoprotein 是由 29 个氨基酸残基构成的细胞穿透肽，来源于狂犬病病毒糖蛋白，它能够穿过血脑屏障，进入脑细胞。

Rabies Virus Glycoprotein is a 29-amino-acid cell penetrating peptide derived from a rabies virus glycoprotein that can cross the blood-brain barrier (BBB) and enter brain cells.

它是从狂犬病病毒糖蛋白（RVG）中提取的29个氨基酸的片段肽。由于嗜神经病毒通过血脑屏障感染脑细胞，因此可以使用相同的策略进入中枢神经系统并将siRNA输送到大脑。它与神经元细胞表达的乙酰胆碱受体特异性结合。

It is a 29 amino acid fragment peptide extracted from rabies virus glycoprotein (RVG). Since neurotropic viruses infect brain cells across the blood-brain barrier, the same strategy may be used to enter the central nervous system and deliver siRNA to the brain. It binds specifically to the acetylcholine receptor expressed by neuronal cells.
