Controlling Neurons May Ease Parkinson's Disease

Blocking or eliminating a specific potassium channel in a small group of brain cells may improve or prevent the symptoms of Parkinson's disease, a debilitating and progressive neurodegenerative disease that afflicts over 1 million people in the United States. In Parkinson's disease, neurons that release dopamine die. The loss of dopamine causes an array of debilitating symptoms that include resting tremor, muscle rigidity and slowed movement. Although the cause of the disease remains uncertain, James Surmeier and colleagues at Northwestern University have discovered a way of potentially lessening the symptoms and progression of the disease. The investigators describe their findings in the March issue of Nature Neuroscience.<
