Abstract
Purpose: Our previous study showed that Er-Bai-Tang decoction (EBT) could effectively improve Parkinson's disease (PD) patients' quality of life, sleep, mood, and cognitive disorders, but the mechanism of EBT to treat PD was unclear. So, our study aimed to explore the mechanism of EBT to treat PD via p38 mitogen-activated protein kinases (MAPK) pathway and intestinal flora.
Methods: In our study, the PD rat model was established by subcutaneously injecting 2 mg/kg/d rotenone solution, and 23.43 g/kgEBT was used to treat PD model rats.
Results: Behavioral test showed that EBT could reverse the motor impairment in the PD model rats. Hematoxylin and eosin result showed that EBT could reduce the cell necrosis in the SNpc area of the PD model rats. Western blotting and real time-polymerase chain reaction showed that EBT could decrease the p38 MAPK expression in the SNpc area of the PD model rats. 16s rRNA sequencing analysis showed that EBT could improve the composition of intestinal flora in the PD model rats. Rikenellaceae at family level and Alistipes and Allobaculum at the genus level were the key species in the PD development and EBT treatment to PD. KEGG showed that EBT might change the iron uptake in PD rats.
Conclusions: EBT could improve the motor symptoms and neuronal injury in the PD model rat, and its mechanism may be related to decreasing p38 MAPK pathway and improving the composition of intestinal flora.
