Gene therapy is safe for Alzheimer's disease

摘要

Insertion of genetically modified cells into the brains of patients with Alzheimer's disease is well tolerated and reduces cognitive decline,according to preliminary findings reported at the American Academy of Neurology last week.In a phase I study,researchers modified skin cells from eight patients to produce nerve growth factor in vitro.These cells were implanted into the patients' brains while they were sedated or anaesthetised.
