Forgotten and lost -- when proteins 'shut down' our brain

Which modules of the tau protein, in neurons of Alzheimer disease patients, may act in a destructive manner were investigated by researchers from the Max Planck Institute for Biophysical Chemistry (Göttingen) and the Max Planck Unit for Structural Molecular Biology (Hamburg) with the help of Nuclear Magnetic Resonance Spectroscopy ( PLoS Biology , February 17, 2009).
