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.

Warren, the founding chair of Emory’s Department of Human Genetics, led an international team that discovered Read more
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
What applies to meat, vegetables and fish may also apply to cells for use in cell therapy: frozen often isn’t quite as good.
Ian Copland and colleagues from Emory’s Personalized Immunotherapy Center have a paper this week in Stem Cells Reports discussing how freezing and thawing stem cells messes them up. Specifically, it disrupts their actin cytoskeletons and impairs their ability to find their niches in the body. Culturing the cells for 48 hours after thawing does seem to correct the problem, though.
The findings have some straightforward implications for researchers planning to testÂ cell therapies inÂ clinical applications. The authors conclude:
Until such time as a cryopreservation and thawing procedure can yield a viable and fully functional MSC product immediately after thawing, our data support the idea of using live MSCs rather than post-thaw cryo MSCs for clinical evaluation of MSCs as an immunosuppressive agent.
Notably, the Emory Personalized Immunotherapy Center has built a process designed around offering never-frozen autologous (that is, the patient’s own)Â mesenchymal stem cells, as therapies for autoimmune disordersÂ such as Crohn’s disease.
Can it really be possible to transform a person’s own cells into a weapon against various forms of disease? And what if those very cells could be retrained to attack cancer cells or to prevent autoimmune diseases?
Answers to these questions and many more are about to soon be realized, as Emory University Hospital will serve as the launch site for the very appropriately-named EPIC (Emory Personalized Immunotherapy Center).
The new Center, which is the creation of Dr. Jacques Galipeau, MD, professor of hematology and medical oncology & pediatrics of Emory University, will soon be operational after final touches have been put on construction of the lab. This cell processing facility will foster development of novel personalized cellular therapies for Emory patients facing catastrophic ailments and unmet medical needs.
According to Galipeau, the premise of EPIC and its overlying mission will focus on cellular and biological therapies that use a patientâ€™s own cells as a weapon to seek and destroy cells that actually make a person sick. In partnership with the Winship Cancer Institute of Emory University, Childrenâ€™s Healthcare of Atlanta, Aflac Cancer & Blood Disorders Center and the Emory School of Medicine, EPIC seeks to improve the health of children and adults afflicted with cancer and immune disease.
â€œFirst and foremost, we seek to bring a level of care and discovery that is first in Georgia, first in human and first in child. Blood and marrow derived cells have been used for more than a quarter century to treat life threatening hematological conditions and are now established therapies worldwide. More recently, the use of specific adult somatic cells from marrow, blood and other tissues are being studied in cellular medicine of a wide array of ailments including heart, lung, neurological and immune diseases,â€ says Galipeau. â€œThe use of blood borne immune cells can also be exploited for treatment of cancer, autoimmune disease, organ transplantation and chronic viral illnesses such as HIV.â€
Galipeau said that once operational, EPIC willÂ begin by working with Crohnâ€™s disease in pediatric and adult patients, an inflammatory bowel disease. Symptoms of Crohnâ€™s disease include severe abdominal pain, diarrhea, fever, weight loss, and the inability for a child to properly grow. Resulting bouts of inflammation may also affect the entire digestive tract, including the mouth, esophagus and stomach.Â In some cases, a radical surgery involving the removal of part of the lower intestinal tract is required.
â€œThere is no current answer for what specifically causes Crohnâ€™s disease, nor is there a cure. But we hope that through our research and efforts, we will be able to first target the inflammatory mechanisms in these patients through immunotherapy, and in turn reduce the amount of flare-ups and limitÂ the damage that occurs from this disease,â€ says Galipeau.
Galipeau says the EPIC program could represent a powerful cornerstone to the launch and the development of an entirely new, Emory-based initiative which bundles the strengths of the School of Medicine, Emory University Hospital, Children’s Healthcare of Atlanta, and many Woodruff Health Sciences Center centers of excellence,â€ says Galipeau.
â€œMy ultimate goal is to elevate the biomedical scientific and scholarly enterprise to aÂ higher level – making a difference in the lives of people. The EPIC program and multi-levels of support could be a fundamental underpinning to our success.â€
