Warren symposium follows legacy of geneticist giant

If we want to understand how the brain creates memories, and how genetic disorders distort the brain’s machinery, then the fragile X gene is an ideal place to start. That’s why the Stephen T. Warren Memorial Symposium, taking place November 28-29 at Emory, will be a significant event for those interested in neuroscience and genetics. Stephen T. Warren, 1953-2021 Warren, the founding chair of Emory’s Department of Human Genetics, led an international team that discovered Read more

Tracing the start of COVID-19 in GA

At a time when COVID-19 appears to be receding in much of Georgia, it’s worth revisiting the start of the pandemic in early 2020. Emory virologist Anne Piantadosi and colleagues have a paper in Viral Evolution on the earliest SARS-CoV-2 genetic sequences detected in Georgia. Analyzing relationships between those virus sequences and samples from other states and countries can give us an idea about where the first COVID-19 infections in Georgia came from. We can draw 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
