疑似导致帕金森病 (PD) 病理生理学的环境暴露包括潜在的神经毒性农药,这些农药与帕金森病风险增加有关。相反,腺苷拮抗剂咖啡因等可能的保护因素与降低疾病风险有关。在此,我们评估了咖啡因是否会改变因接触环境相关农药(百草枯和代森锰)超过 8 周而引起的多巴胺能神经元损失。使用体视学方法评估酪氨酸羟化酶免疫反应性 (TH+) 阳性的黑质神经元数量,发现联合农药处理后黑质神经元数量显着减少(至对照的 60%)。 20 mg/kg 的咖啡因显着减少了 TH+ 神经元的损失(达到相应对照的 85%)。结果证明咖啡因在 PD 模型的慢性农药暴露模型中具有神经保护潜力。
Environmental exposures suspected of contributing to the pathophysiology of Parkinson’s disease (PD) include potentially neurotoxic pesticides, which have been linked to an increased risk of PD. Conversely, possible protective factors such as the adenosine antagonist caffeine have been linked to a reduced risk of the disease. Here we assessed whether caffeine alters dopaminergic neuron loss induced by exposure to environmentally relevant pesticides (paraquat and maneb) over 8 weeks. The number of nigral neurons positive for tyrosine hydroxylase immunoreactivity (TH+) was assessed using stereological methods and found to be significantly reduced (to 60% of control) by combined pesticide treatment. Caffeine at 20 mg/kg significantly reduced TH+ neuron loss (to 85% of the respective control). The results demonstrate the neuroprotective potential of caffeine in a chronic pesticide exposure model of model of PD.
