Chrysin restores MPTP induced neuroinflammation, oxidative stress and neurotrophic factors in an acute Parkinson's disease mouse model.

Parkinson disease occurs due to the depletion of dopaminergic neurons in brain resulting in decreased dopamine level and abnormal protein aggregation. Chrysin is a flavonoid which possesses pharmacological properties against various diseases like hypertension, diabetes, cancer, etc. According to the recent literatures, it is evidenced that chrysin protects mice against Focal Cerebral Ischemia/Reperfusion Injury. The present study aimed to elucidate the effect of chrysin on neuronal restoration in MPTP intoxicated acute mice model. From the results, it is revealed that the pre-treatment with chrysin protected MPTP induced degeneration of nigra-striatal neurons. It is observed that chrysin also ameliorates MPTP induced oxidative stress in mice by upregulating GSH, SOD and downregulating LPO levels. The motor dysfunction is also found to be enhanced which was evidenced through Beam walk, Horizontal grid and vertical grid tests. Pre-treatment with chrysin also averted MPTP induced alterations in neurotrophic factors, inflammatory markers and Dopamine contents. The findings of the present study clearly indicated that the chrysin reversed the neurochemical deficits, oxidative stress and behavioral abnormalities in PD mice and offers promising strategy for the treatment of neurodegenerative diseases.
