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

Graft vs host? Target the aurora

 

Graft-vs-host disease is a common and potentially deadly complication following bone marrow transplants, in which immune cells from the donated bone marrow attack the recipient’s body.

Winship Cancer Institute’s Ned Waller and researchers from Children’s Healthcare of Atlanta and Yerkes National Primate Research Center were part of a recent Science Translational Medicine paper that draws a bright red circle around aurora kinase A as a likely drug target in graft-vs-host disease.

Aurora kinases are enzymes that control mitosis, the process of cell division, and were first discovered in the 1990s in yeast, flies and frogs. Now drugs that inhibit aurora kinase A are in clinical trials for several types of cancer, and clinicans are planning to examine whether the same type of drugs could help with graft-vs-host disease.

Leslie Kean, a pediatric cancer specialist at Seattle Children’s who was at Emory until 2013, is the senior author of the STM paper. Seattle Childrens’ press release says that Kean wears a bracelet around her badge from a pediatric patient cured of leukemia one year ago, but who is still in the hospital due to complications from graft-vs-host.
