First (and massive) whole-genome study of IBD in African Americans

In African Americans, the genetic risk landscape for inflammatory bowel disease (IBD) is very different from that of people with European ancestry, according to results of the first whole-genome study of IBD in African Americans. The authors say that future clinical research on IBD needs to take ancestry into account. Findings of the multi-center study, which analyzed the whole genomes of more than 1,700 affected individuals with Crohn’s disease and ulcerative colitis and more than Read more

Emory researchers SNARE new Alzheimer’s targets

Diving deep into Alzheimer’s data sets, a recent Emory Brain Health Center paper in Nature Genetics spots several new potential therapeutic targets, only one of which had been previous linked to Alzheimer’s. The Emory analysis was highlighted by the Alzheimer’s site Alzforum, gathering several positive comments from other researchers. Thomas Wingo, MD Lead author Thomas Wingo and his team -- wife Aliza Wingo is first author – identified the targets by taking a new approach: tracing Read more

Alzheimer’s drug discovery: looking under the right ROCK

Developing drugs that can change the progression of Alzheimer’s disease is a huge challenge. In the last few years, more than one pharmaceutical firm have abandoned clinical programs in Alzheimer’s that once looked promising. Still, Emory and Scripps scientists have found an approach that deserves a second look and more investigation.

One straightforward drug strategy against Alzheimer’s is to turn down the brain’s production of beta-amyloid, the key component of the disease’s characteristic plaques. A toxic fragment of a protein found in healthy brains, beta-amyloid accumulates in the brains of people affected by the disease.

The enzyme that determines how much beta-amyloid brain cells generate is called BACE (beta-secretase or beta-site APP cleaving enzyme). Yet finding drugs that inhibit that elusive enzyme has been far from straightforward.

Now researchers  have identified a way to shut down production of beta-amyloid by diverting BACE to a different part of the cell and inhibiting its activity. The results were published this week in Journal of Neuroscience. Read more
