To investigate the expression and role of nicotinic acetylcholine α7 subunit (nAChRα7) in the hippocampus of rats with Parkinson's disease (PD) and Parkinson's disease dementia (PDD). PD model was established with 6-hydroxydopa. Then, methyllycaconitine was further used to prepare a PDD model. The behavioral indexes and malondialdehyde (MDA) and superoxide dismutase (SOD) levels were measured. The mRNA level and protein level of nAChRα7 in hippocampus was detected by reverse transcription quantitative polymerase chain reaction (RT-qPCR) and Western-blot, respectively. The α7nAchR and NeuN protein was detected by immunofluorescence. Compared with the PD model group, the escape latency of the PDD model group was significantly prolonged while the times of crossing platforms was significantly reduced (p < 0.05). The SOD level in the PDD and PD group decreased as compared with the control group (p < 0.05), while the MDA content increased (p < 0.05). The mRNA level and protein expression of nAChRα7 in the PDD and PD model group was significantly lower than that in the control group (p < 0.05). There was a significant difference in the nAChRα7 protein level between the PDD and PD model group (p < 0.05). Together, the nAChRα7 receptor level was significantly decreased in the PDD model group, indicating that the decrease in the nAChRα7 receptor levels is a possible mechanism of the pathogenesis of PDD.
