ScienceDaily (Feb. 7, 2012) — Parkinson's disease researchers at the University at Buffalo have discovered how mutations in the parkin gene cause the disease, which afflicts at least 500,000 Americans and for which there is no cure. The results are published in the current issue of Nature Communications. The UB findings reveal potential new drug targets for the disease as well as a screening platform for discovering new treatments that might mimic the protective functions of parkin. UB has applied for patent protection on the screening platform. "This is the first time that human dopamine neurons have ever been generated from Parkinson's disease patients with parkin mutations," says Jian Feng, PhD, professor of physiology and biophysics in the UB School of Medicine and Biomedical Sciences and the study's lead author. As the first study of human neurons affected by parkin, the UB research overcomes a major roadblock in research on Parkinson's disease and on neurological diseases in general. The problem has been that human neurons live in a complex network in the brain and thus are off-limits to invasive studies, Feng explains. "Before this, we didn't even think about being able to study the disease in human neurons," he says. … Continue reading
