Nonviral DNA vaccine shows promise of a safe treatment for Alzheimers disease

Scientists in Japan have found a nonviral DNA vaccine that reduces the deposition of amyloid peptides, or brain plaque, associated with Alzheimers disease without the risk of meningoencephalitis. The article appears in the latest issue of PNAS (thanks to Slashdot for the link). In mice these researchers were able to reduce the amount of amyloid peptides by 50% at 18 months of age. Cross your fingers for the clinical trials with humans.
