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

Unexpected effect on flu immunity

Immunologists reported recently that the drug rapamycin, normally used to restrain the immune system after organ transplant, has the unexpected ability to broaden the activity of a flu vaccine.

The results, published in Nature Immunology, indicate that rapamycin steers immune cells away from producing antibodies that strongly target a particular flu strain, in favor of those that block a wide variety of strains. The results could help in the effort to develop a universal flu vaccine.

This study was inspired by a 2009 Nature study from Koichi Araki and Emory Vaccine Center director Rafi Ahmed, reports Jon Cohen in Science magazine. Read more
