Rabies Virus Glycoprotein 是由 29 個氨基酸殘基構成的細胞穿透肽，來源于狂犬病病毒糖蛋白，它能夠穿過血腦屏障，進入腦細胞。

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.

它是從狂犬病病毒糖蛋白（RVG）中提取的29個氨基酸的片段肽。由于嗜神經病毒通過血腦屏障感染腦細胞，因此可以使用相同的策略進入中樞神經系統并將siRNA輸送到大腦。它與神經元細胞表達的乙酰膽堿受體特異性結合。

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.
