Parkinson's disease (PD) is the most prevalent movement disorder. Curcumin, a polyphenol with hydrophobic properties, has been proved against Parkinson. Our previous study suggested that curcumin's effectiveness in treating Parkinson's disease may be linked to the gut-brain axis, although the specific mechanism by which curcumin exerts neuroprotective effects in the brain remains unknown.
The therapeutic efficacy of curcumin was evaluated using behavioral tests, immunofluorescence of tyrosine hydroxylase (TH). Network pharmacology and transcriptomics predicted the mechanisms of curcumin in PD. Activation of the phosphatidylinositol 3-kinase PI3K/AKT pathway was confirmed by quantitative polymerase chain reaction (qPCR) and immunofluorescence.
Curcumin restored the dyskinesia and dopaminergic neurons damage of MPTP-induced mice. Curcumin against Parkinson's disease by regulating inflammation, oxidative stress, and aging. The mechanisms of these were associated with activation of PI3K / AKT pathway.
In conclusion, the neuroprotective mechanisms of curcumin activate PI3K / AKT pathway in Parkinson's disease was revealed by our study.
帕金森病(PD)是最常见的运动障碍。姜黄素是一种具有疏水性的多酚,已被证明可对抗帕金森病。我们之前的研究表明,姜黄素治疗帕金森病的有效性可能与肠脑轴有关,尽管姜黄素在大脑中发挥神经保护作用的具体机制尚不清楚。
使用行为测试、酪氨酸羟化酶(TH)免疫荧光评估姜黄素的治疗功效。网络药理学和转录组学预测了姜黄素在 PD 中的作用机制。通过定量聚合酶链反应(qPCR)和免疫荧光验证了磷酸肌醇 3-激酶 PI3K/AKT 途径的激活。
姜黄素恢复了 MPTP 诱导的小鼠运动障碍和多巴胺能神经元损伤。姜黄素通过调节炎症、氧化应激和衰老来对抗帕金森病。这些机制与 PI3K/AKT 途径的激活有关。
综上所述,本研究揭示了姜黄素通过激活 PI3K/AKT 通路发挥其在帕金森病中的神经保护作用。
