涉及非法使用阿片类药物的过量死亡人数急剧增加,已被宣布为美国的全国危机。吸毒过量死亡人数不断增加的部分原因是美国海洛因供应中芬太尼污染的频率增加。为了对抗这一日益增长的趋势,我们设计了一种含有海洛因和芬太尼半抗原结合物混合物的疫苗,作为针对这些药物组合的概念验证免疫疗法。用混合疫苗免疫的啮齿类动物在静脉推注海洛因与芬太尼(10% w/w)后,显示出血清中的药物滞留和大脑中的分布减少。此外,在抗伤害行为模型中,混合疫苗的表现与单独的免疫缀合物疫苗一样好,甚至更好,并且能够识别其他六种具有纳摩尔亲和力的芬太尼类似物。总而言之,这些数据凸显了针对芬太尼污染海洛因的混合疫苗的潜力。
The sharp increase in overdose deaths involving illicit opioid use has been declared a national crisis in the United States. This growing number of overdose deaths can in part be attributed to the increased frequency of fentanyl contamination in the United States heroin supply. To combat this growing trend, we designed a vaccine containing a mixture of heroin and fentanyl hapten-conjugates as a proof-of-concept immunotherapy targeting a combination of these drugs. Rodents immunized with the admixture vaccine showed drug retention in serum and reduced distribution in the brain after administration of an intravenous bolus of heroin coadministered with fentanyl (10% w/w). Moreover, the admixture vaccine performed as well as or better than individual immunoconjugate vaccines in antinociception behavioral models and recognized six other fentanyl analogues with nanomolar affinity. Taken together, these data highlight the potential of an admixture vaccine against heroin contaminated with fentanyl.
