Objectives

To observe the effects of electroacupuncture (EA) at "Fengfu" (GV16), "Taichong" (LR3) and "Zusanli" (ST36) on α-synuclein (α-syn), Occludin, Claudin-1, thioredoxin interaction protein (TXNIP) and Nod-like receptor 3 (NLRP3) in Parkinson's disease (PD) mice, so as to investigate the mechanisms of EA on intestinal barrier function and inflammation in PD mice.

Methods

Thirty six C57BL/6 mice were randomly divided into control, model and EA groups, with 12 mice in each group. PD mice model was induced by rotenone intragastric administration for 28 days. Mice in the EA group were treated with EA (2 Hz, 1 mA) at GV16, LR3 and ST36 for 30 min, once a day for 14 days. The behavioral scores were observed. The total distance of autonomic movement was measured by open field test. The expression level of α-syn in substantia nigra and colon tissue was determined by immunohistochemistry. The colonic morphology and goblet cell distribution were observed by Alcian blue staining. The expression levels of Occludin, Claudin-1, TXNIP and NLRP3 mRNA in colon tissue were detected by real-time fluorescence quantitative PCR.

Results

Compared with the control group, the behavioral scores of rats were increased (P<0.01)；the total distance of autonomous movement was decreased (P<0.01)；the positive expression level of α-syn in the substantia nigra and colon was increased (P<0.01)；the goblet cells and crypts in colon tissue were reduced, and the muscular layer was thinner；the expression levels of Occludin and Claudin-1 mRNAs in colon tissue were decreased (P<0.01) while TXNIP and NLRP3 mRNAs were increased (P<0.01) in the model group. Compared with the model group, the surface villi of colon tissue was more complete, the goblet cells and crypts were increased, and the muscular layer was thickened；the other indexes were reversed (P<0.01, P<0.05) in the EA group.

Conclusions

EA at GV16, LR3 and ST36 can reduce the abnormal accumulation of α-syn in the substania nigra and colon tissue of PD mice, alleviate the damage of intestinal barrier, regulate TXNIP/NLRP3 signaling pathway, so as to delay the occurrence and development of PD."xsd:string
