Genetic manipulation of urate alters neurodegeneration in mouse model of Parkinson's disease

A study by Massachusetts General Hospital researchers adds further support to the possibility that increasing levels of the antioxidant urate may protect against Parkinson's disease. In their report published in PNAS Early Edition, the investigators report that mice with a genetic mutation increasing urate levels were protected against the kind of neurodegeneration that underlies Parkinson's disease, while the damage was worse in animals with abnormally low urate.
