2004 MAY 5 - (NewsRx.com & NewsRx.net) -- Researchers review current concepts and future prospects for Alzheimer disease vaccines in a recent issue of the journal Alzheimer Disease and Associated Disorders.
"Alzheimer disease (AD) is the most prevalent form of dementia worldwide and is characterized by the progressive accumulation of the 42-residue amyloid beta protein (A-beta) in brain regions serving memory and cognition. Only a few years ago, the proposition that AD may be amenable to any kind of therapy would have met with considerable skepticism. Yet, recent, exciting developments appear to suggest that immunizing against A-beta may bear some potential for arresting or even curing AD," investigators in Switzerland, the United States, and Canada report.
"However, a clinical trial of vaccination with synthetic human A-beta in AD patients was halted because of the development of meningoencephalitis in some patients," said Frank L. Heppner at the Institute of Neuropathology in Switzerland and collaborators in the U.S. and Canada. "Further studies aimed at elucidating the mechanism of A-beta clearance ...
