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

Exosomes as potential biomarkers of radiation exposure

Kishore Kumar Jella, PhD

Winship Cancer Institute postdoc Kishore Kumar Jella has been invited to speak at the NATO advanced research workshop BRITE (Biomarkers of Radiation In the Environment): Robust tools for Risk Assessment in Yerevan, Armenia, on 28-30 November, 2017. The workshop brings together leading international experts to evaluate currently and developing radiation biomarkers for environmental applications.

Jella works in the Departments of Biochemistry and Radiation Oncology under the direction of Professors William S. Dynan and Mohammad K. Khan. He will speak on “Exosomes as Radiation Biomarkers”. He will describe how radiation influences exosome production and how these exosomes influence the immune system. The work has applications both to radiation carcinogenesis and combination radio-immunotherapy.

Jella is supported in part by a grant from the National Aeronautics and Space Administration to Dynan.

Exosomes are nano-sized membrane-clothed capsules containing proteins and RNA that are thought to facilitate cell-cell communcation. They were previously implicated in the ability of cancer cells to influence healthy neighbor cells, and have also been proposed as anti-cancer therapeutic vehicles. Jella’s previous research on exosomes and radiation-induced bystander signaling was published in Radiation Research in 2014.
