Numerous studies have shown that neuroinflammation is involved in the process of neuronal damage in neurodegenerative diseases such as Parkinson's disease (PD), for example, and that inhibiting neuroinflammation help improve PD. Shikimic acid (SA) has anti-inflammatory, analgesic and antioxidant activities in numerous diseases. However, its effect and mechanism in PD remain unclear. In this experiment, we found that SA inhibits production of pro-inflammatory mediators and ROS in LPS-induced BV2 cells. Mechanistic studies demonstrated that SA suppresses neuro-inflammation by activating the AKT/Nrf2 pathway and inhibiting the NF-κB pathway. Further study, we confirmed that SA ameliorated the neurological damage and behavioral deficits caused by LPS injection in mice. In summary, these study highlighted the beneficial role of SA as a novel therapy with potential PD drug by targeting neuro-inflammation.
大量研究表明,例如在帕金森病(PD)等神经退行性疾病中,神经炎症参与神经元损伤过程,并且抑制神经炎症有助于改善帕金森病。莽草酸(SA)在多种疾病中具有抗炎、镇痛和抗氧化活性。然而,其在帕金森病中的作用和机制仍不清楚。在本实验中,我们发现莽草酸可抑制脂多糖诱导的BV2细胞中促炎介质和活性氧的产生。机制研究表明,莽草酸通过激活AKT/Nrf2通路和抑制NF-κB通路来抑制神经炎症。进一步研究发现,莽草酸可改善脂多糖注射所致小鼠的神经损伤和行为缺陷。总之,这些研究突出了莽草酸作为一种通过靶向神经炎症治疗帕金森病的潜在新型药物的有益作用。
