Gene therapy prevents memory problems in mice with Alzheimer's disease
Date:11/28/2010

," said Lennart Mucke, MD, director of the GIND and senior author of the study. "We were absolutely thrilled to discover that it did."

Increasing EphB2 levels in neurons of mice engineered to produce high levels of human amyloid proteins in the brain prevented their neurotransmission deficits, memory problems and behavioral abnormalities. The scientists also discovered that amyloid proteins directly bind to EphB2 and cause its degradation, which helps explain why EphB2 levels are reduced in AD and related mouse models.

"Based on our results, we think that blocking amyloid proteins from binding to EphB2 and enhancing EphB2 levels or functions with drugs might be of benefit in AD." said Mucke. "We are excited about these possibilities and look forward to pursuing them in future studies."
