A Vaccine Strategy that Induces Protective Immunity against Heroin
摘要:
Heroin addiction is a wide-reaching problem with a spectrum of damaging social consequences. A vaccine capable of blocking heroin's effects could provide a long-lasting and sustainable adjunct to heroin addiction therapy. Heroin, however, presents a particularly challenging immunotherapeutic target, as it is metabolized to multiple psychoactive molecules. To reconcile this dilemma, we examined the idea of a singular vaccine with the potential to display multiple drug-like antigens; thus two haptens were synthesized, one heroin-like and another morphine-like in chemical structure. A key feature in this approach is that immunopresentation with the heroin-like hapten is thought to be immunochemically dynamic such that multiple haptens are simultaneously presented to the immune system. We demonstrate the significance of this approach through the extremely rapid generation of robust polyclonal antibody titers with remarkable specificity. Importantly, both the antinociceptive effects of heroin and acquisition of heroin self-administration were blocked in rats vaccinated using the heroin-like hapten.

The present invention provides novel heroin hapten compounds and heroin immunoconjugates which can be used for in vivo production of antibodies that specifically bind to heroin and its psychoactive metabolites. The invention also provides methods of using vaccines comprising the heroin immunoconjugates in active or passive immunization protocols. The compositions and methods of the invention are useful for prevention and treatment of heroin addiction.
