Imagine you have a superhero named Uric Acid who is fighting against the villain α-synuclein, the main culprit in Parkinson’s disease. Uric Acid swoops in and saves the day by reducing the transmission of α-synuclein between brain cells, ultimately protecting the precious dopaminergic neurons. This study found that by elevating levels of Uric Acid, the propagation of α-synuclein was inhibited and the survival of dopaminergic neurons increased. Interestingly, Uric Acid accomplished this by regulating endocytosis, a process similar to how a cell can take in external substances like a Venus flytrap capturing prey. These exciting results suggest that Uric Acid could be a potential game-changer in treating Parkinson’s disease. But hold on! We still need more research to explore exactly how Uric Acid exerts its protective effects and how it could be harnessed as a therapy. So get your lab coats on and join the quest to uncover the secrets of Uric Acid and its potential role in battling Parkinson’s disease!
Ample evidence demonstrates that α-synuclein (α-syn) has a critical role in the pathogenesis of Parkinson’s disease (PD) with evidence indicating that its propagation from one area of the brain to others may be the primary mechanism for disease progression. Uric acid (UA), a natural antioxidant, has been proposed as a potential disease modifying candidate in PD. In the present study, we investigated whether UA treatment modulates cell-to-cell transmission of extracellular α-syn and protects dopaminergic neurons in the α-syn-enriched model. In a cellular model, UA treatment decreased internalized cytosolic α-syn levels and neuron-to-neuron transmission of α-syn in donor-acceptor cell models by modulating dynamin-mediated and clathrin-mediated endocytosis. Moreover, UA elevation in α-syn-inoculated mice inhibited propagation of extracellular α-syn which decreased expression of phosphorylated α-syn in the dopaminergic neurons of the substantia nigra leading to their increased survival. UA treatment did not lead to change in markers related with autophagolysosomal and microglial activity under the same experimental conditions. These findings suggest UA may control the pathological conditions of PD via additive mechanisms which modulate the propagation of α-syn.
