Potential Gene Therapy for Cocaine Addiction
February 12, 2020
(The Conversation) – Beginning more than 20 years ago, scientists have worked to engineer a new version of a human protein that could break down cocaine so quickly that it doesn’t produce an addictive high. We all have the normal human protein BChE that helps regulate neurotransmitters, and which can slowly break down cocaine. Targeted mutations in BChE can turn it into a super-CocH – a protein that can quickly break down cocaine. When this CocH is injected into the bloodstream, it breaks down cocaine very fast – before the user can experience the pleasurable effects – so a dose of cocaine is less rewarding. Being less rewarding means it is easier to stop using cocaine.
