Researchers have made progress in the effort to create a vaccine against Parkinson’s disease. The strides were seen in tests on mice. It’s not known if years of additional research will eventually help prevent or cure the disease in people. Still, “this shows the first demonstration of a vaccine for this family of disease,” says Eliezer Masliah, MD, in a news release. Masliah is a neurosciences and pathology professor at the University of California at San Diego (UCSD). He and colleagues from UCSD and Elan Pharmaceuticals worked on the vaccine project, which is described in Neuron’s June 16 issue.
