Background: Parkinsonism is a neurodegenerative disorder that affects elderly people worldwide. Methods: Curcumin, adenosine A2AR antagonist (ZM241385) and Sinemet® (L-dopa) were evaluated against Parkinson’s disease (PD) induced by rotenone in rats and comparativelyrelatively compared with our previous study on mice model. Results: Rats injected with rotenone showed severe alterations in adenosine A2A receptor gene expression, oxidative stress markers, inflammatory mediator, energetic indices, apoptotic marker and DNA fragmentation levels as compare with the control group. Treatments with curcumin, ZM241385, and Sinemet® restored all the selected parameters. The brain histopathological features of cerebellum regions confirmed our results. By comparing our results with the previous results on mice, we noticed that mice respond to rotenone toxicity and treatments more than rats regarding to behavioral observation, A2AR gene expression, neurotransmitter levels, inflammatory mediator and apoptotic markers, while rats showed higher response to treatments regarding to oxidative stress and energetic indices. Conclusion: Curcumin succeeded to attenuate the severe effects of Parkinson’s disease in rat model and can be consider as a potential dietary supplement. Adenosine A2AR antagonist has almost the same pattern of improvement as Sinemet® and may be considered as a promising therapy against PD. By comparing the role of animal species in response to PD symptoms and treatments, our previous report on mice explore the response of mice to rotenone toxicity than rats, while rats showed higher response to treatments. Therefore, no animal model can perfectly recapitulate all the pathologies of PD.
