Genetic mutation (synuclein) increases risk of Parkinson’s disease from pesticides

“For the first time, we have used human stem cells derived from Parkinson’s disease patients to show that a genetic mutation combined with exposure to pesticides creates a ‘double hit’ scenario, producing free radicals in neurons that disable specific molecular pathways that cause nerve-cell death,” says Stuart Lipton, M.D., Ph.D., professor and director of Sanford-Burnham’s Del E. Webb Center for Neuroscience, Aging, and Stem Cell Research and senior author of the study. -
