When telephone lines go down, or Internet connections are lost, our communities temporarily come to a halt. What if something similar were found to be happening in Parkinson's? This is the focus of Dr. Schmitz and her team at the PDF Research Center at Columbia University Medical Center.

Mangiferin, a polyphenol compound of C-glucoside, is well-known for its anti-inflammatory, antioxidant, anticancer, antidiabetic and cognitive enhancement properties. In this study, we investigated the neuroprotective effect of mangiferin against 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) mouse model of Parkinson's disease (PD), which is most popular and widely used to evaluate therapeutic implications of new protective agents. Male C57BL/6J mice were orally treated with mangiferin (10, 20 and 40mg/kg body wt.) for 14days and from 10th day onwards MPTP (30mg/kg, i.p.) was injected for last 5days. MPTP treatment leads to enhanced oxidative stress, induction of apoptosis (upregulates the expression of Bax, proapoptotic protein and downregulates the expression of anti-apoptotic marker Bcl-2), and loss of dopominergic neurons which results in motor impairments. Results of our study confirmed that mangiferin prevented MPTP-induced behavioral deficits, oxidative stress, apoptosis, dopaminergic neuronal degeneration and dopamine depletion. Taken together, we conclude that mangiferin attenuates the dopaminergic neurodegeneration mainly through its potent antioxidant and antiapoptotic properties.
