Renewed Hopes for Beta-Amyloid Vaccine to Treat Alzheimer's

Science & Technology at Scientific American.com: Renewed Hopes for Vaccine to Treat Alzheimer's: "After just four months of biweekly injections, mice in the preventative group had as much as 30 percent less beta-amyloid buildup than untreated controls had; after a year, up to 50 percent less. 'The final reduction rate of beta amyloid burden in the cerebral cortex at 18 months of age was roughly 38.5 percent of untreated groups,' the team writes in their report, published online this week by the Proceedings of the National Academy of Sciences."
