Alzheimer's disease (AD) is one of the most common neurodegenerative diseases, and no effective therapies have been found to prevent or cure AD to date. Berberine and curcumin are extracts from traditional Chinese herbs that have a long history of clinical benefits for AD. Here, using a transgenic AD mouse model, we found that the combined berberine and curcumin treatment had a much better effect on improving the cognitive function of mice than the single-drug treatment, suggesting synergic effects of the combined berberine and curcumin treatment. In addition, we found that the combined berberine and curcumin treatment had significant synergic effects on reducing soluble amyloid-β-peptide(1-42) production. Furthermore, the combination treatment also had remarkable synergic effects on decreasing inflammatory responses and oxidative stress in both the cortex and hippocampus of AD mice. We also found that the combination treatment performed much better than the single drugs in reducing the APP and BACE1 levels and increasing AMPKα phosphorylation and cell autophagy, which might be the underlying mechanism of the synergic effects. Taken together, the result of this study reveal the synergic effects and potential underlying mechanisms of the combined berberine and curcumin treatment in improving the symptoms of AD in mice. This study sheds light on a new strategy for exploring new phytotherapies for AD and also emphasizes that more research should focus on the synergic effects of herbal drugs in the future.

小ber碱和姜黄素对改善阿尔茨海默氏病小鼠模型认知功能的协同作用。

阿尔茨海默氏病(AD)是最常见的神经退行性疾病之一,迄今为止,尚未发现有效的疗法来预防或治愈AD。小ber碱和姜黄素是传统中草药的提取物,对AD具有长期的临床益处。在这里,使用转基因AD小鼠模型,我们发现小碱和姜黄素联合治疗比单药治疗对改善小鼠的认知功能有更好的效果,表明小ber碱和姜黄素联合治疗具有协同作用。此外,我们发现小碱和姜黄素联合治疗对减少可溶性淀粉样蛋白-β-肽(1-42)的产生具有明显的协同作用。此外,联合治疗对降低AD小鼠皮层和海马的炎症反应和氧化应激也具有显着的协同作用。我们还发现,在降低APP和BACE1水平以及增加AMPKα磷酸化和细胞自噬方面,联合治疗的效果比单一药物好得多,这可能是协同作用的潜在机制。两者合计,这项研究的结果揭示了小碱和姜黄素联合治疗改善小鼠AD症状的协同作用和潜在的潜在机制。这项研究为探索用于AD的新植物疗法的新策略提供了亮点,并强调未来更多的研究应集中在草药的协同作用上。我们还发现,联合治疗在降低APP和BACE1水平以及增加AMPKα磷酸化和细胞自噬方面比单药更好,这可能是协同作用的潜在机制。两者合计,这项研究的结果揭示了小碱和姜黄素联合治疗改善小鼠AD症状的协同作用和潜在的潜在机制。这项研究为探索用于AD的新植物疗法的新策略提供了亮点,并强调未来更多的研究应集中在草药的协同作用上。我们还发现,在降低APP和BACE1水平以及增加AMPKα磷酸化和细胞自噬方面,联合治疗的效果比单一药物好得多,这可能是协同作用的潜在机制。两者合计,这项研究的结果揭示了小碱和姜黄素联合治疗改善小鼠AD症状的协同作用和潜在的潜在机制。这项研究为探索用于AD的新植物疗法的新策略提供了亮点,并强调未来更多的研究应集中在草药的协同作用上。两者合计,这项研究的结果揭示了小碱和姜黄素联合治疗改善小鼠AD症状的协同作用和潜在的潜在机制。这项研究为探索用于AD的新植物疗法的新策略提供了亮点,并强调未来更多的研究应集中在草药的协同作用上。两者合计,这项研究的结果揭示了小碱和姜黄素联合治疗改善小鼠AD症状的协同作用和潜在的潜在机制。这项研究为探索用于AD的新植物疗法的新策略提供了亮点,并强调未来更多的研究应集中在草药的协同作用上。
