When Felicia Pagliuca arrived at Duke as a first-year undergraduate student from Asheville, she was only 16, but she was already fascinated by biology and physics.
In 2008, Cynthia Toth, MD, was an accomplished ophthalmologist, retinal surgeon, and clinician-scientist. She had been involved since the 1990s in the early development of optical coherence tomography (OCT), a technology that bounces light waves off different parts of the eye, providing a finely detailed look inside the eye’s tissues. In fact, at the time, OCT research from Toth and others had already changed how sight-robbing macular degeneration in older adults was diagnosed and treated, by revealing retinal tissue that could be measured in images and used to guide treatment and predict the course of the disease.
In a daring yet successful experiment back in 1995, Matthias Gromeier, MD, discovered that genetic recombination of poliovirus with a distant relative, human rhinovirus type 2, eliminates the disease-causing capacity of poliovirus. Yet, the modified virus retains the ability to infect and damage cancerous cells, owing to their abnormal “wiring,” and—more importantly—provides powerful immune stimulation by inducing host antiviral defenses.
Diego Bohórquez, PhD, associate professor in medicine, has become known as a “gut-brain neuroscientist.” His team has shown that neuropod cells, a type of sensor cell in the gut, communicate with the brain and help influence decision making about food. This work opens up the possibility of targeting the gut to treat mental health disorders and has been recognized by the U.S. National Academy of Sciences, the office of the Director of the National Institutes of Health (NIH), the New Yorker, and more.
Finding a way to slow or even stop Alzheimer’s disease is one of the most difficult challenges facing medicine today. Many research and clinical trials have led to promising results over the years, while others have produced disappointing findings. But what if there were a way to get more out of these trials—even the ones with less-than-promising results? What if there were a better way to determine if a drug is hitting its intended target?
To improve the survival of patients with brain tumors, Vidya Chandramohan, PhD, focuses on developing bacterial toxin-based therapies for glioblastoma.
For patients who find themselves slowly beginning to lose vision, today’s doctors have gene replacement therapy as a treatment option. However, there’s a small window of time when the therapy will work best, meaning if a patient isn’t seen soon enough, vision cannot be restored.
Gifts from generous donors have helped researchers who are working to answer basic questions about the human brain—answers that could lead to important discoveries in disease and improve patient outcomes.
In 2021, a baby boy named Easton Sinnamon was the first person in the world to receive a combination heart transplant and allogeneic processed thymus tissue implantation. Six months later, a video showed Easton smiling and playing in a high chair, and tests indicated that the processed thymus tissue was working: building the T cells needed for a well-functioning immune system.
