If you’ve been paying attention to Alzheimer’s disease research, you’ve probably read a lot about beta-amyloid. It’s a toxic protein fragment that dominates the plaques that appear in the brains of people with Alzheimer’s. Many experimental therapies for Alzheimer’s target beta-amyloid, but so far, they’ve not proven effective.

That could be for several reasons. Maybe those treatments started too late to make a difference. But an increasing number of Alzheimer’s researchers are starting to reconsider the field’s emphasis on amyloid. Nature News has a feature this week explaining how the spotlight is shifting to the protein ApoE, encoded by the gene whose variation is responsible for the top genetic risk factor for Alzheimer’s.

In line with this trend, Emory’s Alzheimer’s Disease Research Center recently received a five-year, $7.2 million grant to go beyond the usual suspects like beta-amyloid. Emory will lead several universities in a project to comprehensively examine proteins altered in Alzheimer’s. You’ve heard of the Cancer Genome Atlas? Think of this as the Alzheimer’s Proteome Atlas, potentially addressing the same kind of questions about which changes are the drivers and which are the passengers.

Emory’s back-to-basics proteomics approach has already yielded some scientific fruit, uncovering changes in proteins involved in RNA splicing and processing. Also, the Nature feature also has some background on a clinical trial called TOMMORROW, which Emory’s ADRC is participating in.
