Heroin addiction gene identified and blocked.

A study revealed that cocaine causes a gene in the nucleus accumbens , called AGS3,to rapidly encode masses of proteins that are involved in the cravings and pleasure associated with the drug in 2004.

An AGS3 blocker was then created from a herpes virus. This temporarily binds to proteins and blocks the cravings-pleasure cycle until the virus "washes out " of the body a few weeks later. (More)

阻断海洛因瘾基因

（戒毒新方法）

科学家们发现了与海洛因瘾复发有关的关键性基因，还对其进行了成功阻断，从而使毒瘾得以根除。

2004年的研究发现，可卡因能引起核酸中一个称为AGS3的基因片段快速编制大量蛋白质，而这种蛋白质与毒瘾和毒品引起的欣快感有关。

利用疱疹病毒制成了AGS3阻断剂。这种阻断剂与蛋白暂时结合进而阻断毒瘾发作及产生吸毒欣快感的整个过程，直到几周后这些病毒在体内“失去活力”。
