海洛因成瘾是一个影响广泛的问题,具有一系列破坏性的社会后果。一种能够阻断海洛因影响的疫苗可以为海洛因成瘾治疗提供一种持久和可持续的辅助手段。然而,海洛因是一个特别具有挑战性的免疫治疗靶点,因为它被代谢成多个精神活性分子。为了调和这一困境,我们研究了一种具有展示多种药物样抗原的潜力的单一疫苗的想法;因此合成了两个半抗原,一个在化学结构上类似海洛因,另一个在化学结构上类似吗啡。这种方法的一个关键特征是,用类海洛因半抗原进行免疫抑制被认为是免疫化学动态的,因此多个半抗原同时呈现给免疫系统。我们通过极快地产生具有显著特异性的健壮的多克隆抗体效价来证明这种方法的重要性。重要的是,在使用类海洛因半抗原接种的大鼠中,海洛因的抗伤害性作用和海洛因自我给药的获得都被阻断。
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 though 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.
