多巴胺具有细胞毒性,可能在帕金森病的发展中发挥作用。然而,对它与农药等环境风险因素的相互作用仍然知之甚少。囊泡单胺转运蛋白(VMAT)调节细胞内多巴胺的含量,我们已经测试了VMAT在体内使用的模式生物果蝇的神经保护作用。我们发现,果蝇VMAT(dVMAT)突变体含有较少的多巴胺能神经元比野生型,符合发展的影响,和多巴胺能细胞损失的突变体是由农药鱼藤酮和百草枯加剧。DVMAT蛋白的过表达不会增加暴露于鱼藤酮的动物的存活率,但会阻止这种农药引起的多巴胺能神经元的损失。这些结果是第一个证明VMAT和农药在体内的相互作用,并提供了一个重要的模型,以调查农药和细胞DA可能相互作用,杀死多巴胺能细胞的机制。
Dopamine is cytotoxic and may play a role in the development of Parkinson’s disease. However, its interaction with environmental risk factors such as pesticides remains poorly understood. The vesicular monoamine transporter (VMAT) regulates intracellular dopamine content, and we have tested the neuroprotective effects of VMAT in vivo using the model organism Drosophila melanogaster. We find that Drosophila VMAT (dVMAT) mutants contain fewer dopaminergic neurons than wild type, consistent with a developmental effect, and that dopaminergic cell loss in the mutant is exacerbated by the pesticides rotenone and paraquat. Over-expression of DVMAT protein does not increase the survival of animals exposed to rotenone, but blocks the loss of dopaminergic neurons caused by this pesticide. These results are the first to demonstrate an interaction between a VMAT and pesticides in vivo, and provide an important model to investigate the mechanisms by which pesticides and cellular DA may interact to kill dopaminergic cells.
