BackgroundA time dependent loss of dopaminergic neurons and the formation of intracellular aggregates of alpha synuclein have been reported in PD model flies.MethodsThe progeny (PD flies) expressing human alpha synuclein was exposed to 25, 50, and 100 µM of curcumin mixed in the diet for 24 days. The effect of curcumin was studied on lifespan, activity pattern, oxidative stress, and apoptosis in the brains of PD model flies. The activity of PD model flies was monitored by using Drosophila activity monitors (DAMs). For the estimation of oxidative stress, lipid peroxidation and protein carbonyl content were estimated in the flies brains of each treated groups. The cell death in Drosophila brain was analyzed by isolating brains in Ringer's solution placing them in 70% ethanol and stained in acridine orange to calculate the gray scale values.ResultsThe exposure of flies to 25, 50, and 100 µM of curcumin showed a dose dependent significant delay in the loss of activity pattern, reduction in the oxidative stress and apoptosis, and increase in the life span of PD model flies.ConclusionCurcumin is potent in reducing PD symptoms.
