Marked reductions in opiate receptor binding (-42%), "enkephalinase" activity (-39%), and Met5-enkephalin levels (-72%) accompanied the well-established dopamine depletion in the substantia nigra pars compacta of Parkinsonian subjects. In contrast, enkephalinergic markers were not significantly modified in caudate nucleus.
帕金森病患者黑质致密部中，明显的阿片受体结合减少（-42%）、“脑啡肽酶”活性降低（-39%）以及甲硫氨酸脑啡肽水平下降（-72%）与多巴胺耗竭密切相关。相比之下，尾状核中的脑啡肽能标志物没有显著改变。
