Abstract
Neuroinflammation can cause multiple neurodegenerative diseases, such as Alzheimer's disease (AD), Parkinson's disease (PD), and Huntington's disease (HD). Recent studies have shown that the artemisinin derivative dihydroartemisinin (DHA) can be used as an immunomodulatory, anti-inflammatory and anti-tumor agent. The anti-neuroinflammatory effects of DHA were evaluated in our study, and the underlying mechanisms were explored using the Morris water maze test (MWMT), Open-field test (OFT) and Closed-field test (CFT), Elevated plus maze test (EPMT), Nissl Staining, Immunofluorescence analysis, RT-PCR, and Western Blot. Our results show that DHA significantly inhibits LPS-induced inflammation and attenuates LPS-induced behavioral and memory disorders. 1. Behavioral test results: 1) in the water maze test, the mice in the LPS group showed increased escape latency and length of the movement path on the third day; they also had a decreased number of crossings of the target quadrant after the platform was removed on the 5th day and remained in the target quadrant for less time; 2) in the open- and closed-field experiment, the number of activities and activities in the open-field were significantly reduced; 3) in the elevated cross maz...Continue Reading
