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

Drug discovery: selective anti-inflammatory approach to AD

Anyone familiar with Alzheimer’s disease research can say what a challenge drug development has been. In Emory’s Department of Pharmacology, Thota Ganesh is focusing on an anti-inflammatory approach. Ganesh’s work has been supported by the Alzheimer’s Drug Discovery Foundation and more recently by a five-year, $3.6 million grant from the National Institute on Aging.

Medicinal chemist Thota Ganesh, PhD, is focusing on an anti-inflammatory approach to Alzheimer’s disease, targeting the prostaglandin receptor EP2.

An assistant professor at Emory since 2011, he is continuing research he undertook with Ray Dingledine on EP2 antagonists. In animals, they showed that this class of compounds could reduce injury to the brain after a prolonged seizure. Since then, they have shown that EP2 antagonists have similar effects in protecting against organophosphate pesticides/nerve agents.

EP2 is one of the four receptors for prostaglandin E2, a hormone involved in processes such as fever, childbirth, digestion and blood pressure regulation. Before Ganesh and colleagues from the Emory Chemical Biology Discovery Center started looking for them, chemicals that could block EP2 selectively were not available.

Their idea is: blocking EP2 is a better strategy than the more general approach of going after prostaglandins, the targets for non-steroid anti-inflammatory drugs (NSAIDs) such as aspirin, ibuprofen and celecoxib (Celebrex). Read more
