Parkinson’s Disease (PD) is a chronic neurodegenerative disorder caused by the progressive loss of dopaminergic neurons, leading to decreased dopamine levels in the midbrain. Although the specific etiology of PD is not yet known, oxidative stress, inflammation, and subsequent apoptosis have been proposed to be closely related to PD pathophysiology. Cera Flava (CF) is a natural extract obtained from beehives and is isolated through the heating, compression, filtration, and purification of beehives. CF has been used in traditional medicines for its various clinical and pharmacological effects. However, its effects on neurodegenerative diseases are unknown. Therefore, we investigated the effects of CF against 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced PD in mice and explored the underlying mechanism of action. In MPTP-induced PC12 cells, CF protected NADH dehydrogenase activity and inhibited lactate dehydrogenase. In the mouse model, CF promoted recovery from movement impairments, prevented dopamine depletion, and protected against MPTP-induced dopaminergic neuronal degradation. Moreover, CF downregulated glial and microglial activation. Taken together, our results suggest that CF improves behavioral impairments and protects against dopamine depletion in MPTP-induced toxicity by inhibiting glial and microglial activation.
