Taking another Shot at RAGE to Tame Alzheimer's
Researchers have taken another crack at a promising approach to stopping Alzheimer's disease that encountered a major hurdle last year. In research published this week in the Journal of Clinical Investigation, scientists have developed a compound that targets a molecular actor known asRAGE, which plays a central role in mucking up the brain tissue of people with the disease.
Scientists at the University of Rochester Medical Center and the University of Southern California synthesized a compound that stops RAGE in mice - reversing amyloid deposits, restoring healthy blood flow in the brain, squelching inflammation, and making old, sick mice smarter. But the scientists caution that the work has a long way to go before it's considered as a possible treatment in people.
In the latest work, Zlokovic and colleagues screened thousands of compounds for anti-RAGEactivity and identified three that seemed promising. Then the team turned to chemists Benjamin Miller, Ph.D., and graduate student Nathan Ross. The pair analyzed the compounds' molecular structures, then used that knowledge to create dozens of candidates likely to have activity against RAGE.
