Urate linked to slowed Parkinson's disease
UPI, Published: Oct. 15, 2009 at 2:38 PM http://www.upi.com/Health_News/2009/...0731255631931/ U.S. researchers have found Parkinson's disease progresses more slowly in patients with higher levels of urate. Urate is a salt derived from uric acid. When the body cannot metabolize uric acid properly, urates can build up in body tissues or crystallize within the joints. The study, published online in the Archives of Neurology, found the disease progressed more slowly in patients with the highest levels of urate than in people with the lowest levels.

Use of the antioxidant urate to protect against the neurodegeneration caused by Parkinson's disease appears to rely on more than urate's ability to protect against oxidative damage. In the May issue of the open-access journal PLoS One, researchers from the MassGeneral Institute for Neurodegenerative Diseases (MGH-MIND) describe experiments suggesting the involvement of a novel mechanism in urate's protection of cultured brain cells against Parkinson's-like damage.
"Our experiments showed, unexpectedly, that urate's ability to protect neurons requires the presence of neighboring cells called astrocytes," says Michael Schwarzschild, MD, PhD, of MGH-MIND, the study's senior author. "The results suggest there may be multiple ways that raising urate could help protect against neurodegeneration in diseases like Parkinson's and further support the development of treatments designed to elevate urate in the brain." Schwarzschild and colleagues in the Parkinson's Study Group currently are conducting a clinical trial investigating one approach to that strategy. ... Several epidemiological studies suggested that healthy people with elevated levels of urate, a normal component of the blood, may have a reduced risk of developing Parkinson's disease, and investigations by Schwarzschild's team found that Parkinson's patients with higher naturally occuring urate levels had slower progression of their symptoms... http://www.sciencecodex.com/study_su...echanism-92070
