Gene Therapy, Successful Against Parkinson’s, Continues on the Road to Redemption
Back in the 1980s, gene therapy was one of science’s greatest hopes and hypes, and researchers predicted the technique would be used to cure a huge range of illnesses. During the 90s, many early gene therapy trials were effective or downright dangerous, some causing cancer or even death. But more recently, scientists who stuck with gene therapy have started to see positive results, with promising treatments for malformed hemoglobin, color blindness, and depression. (See the DISCOVER magazine feature “The Second Coming of Gene Therapy” for more.) Now, researchers have announced that they’ve successfully treated the symptoms of Parkinson’s disease in a small group of people—a far cry from a cure, but still a step in the right direction.
