New Implant Turns Immune System Against Alzheimer’s

One of the hypothesized causes of Alzheimer’s is the over-accumulation of the protein amyloid beta (Abeta) in different areas of the brain. This results in the deposition of aggregated protein plaques, which are toxic to neurons. One of the most promising ways to fight the plaques is to “tag” the Abeta proteins with antibodies that signal the patient’s own immune system to attack and clear them.

To be most effective, this treatment has to be given as early as possible, before the first signs of cognitive decline. But this requires repeated vaccine injections, which can cause side effects. EPFL scientists have now solved the problem with an implant that can deliver a steady and safe flow of antibodies to the patient’s brain to clear Abeta proteins. The work is published in the journal Brain.
