New research from Emory University indicates that nearly all people hospitalized with COVID-19 develop virus-neutralizing antibodies within six days of testing positive. The findings will be key in helping researchers understand protective immunity against SARS-CoV-2 and in informing vaccine development.
The test that Emory researchers developed also could help determine whether convalescent plasma from COVID-19 survivors can provide immunity to others, and which donors' plasma should be used.
The antibody test developed by Emory and validated Read more
Emory University played a key role in a landmark international study evaluating the safety and efficacy of the long-acting, injectable drug, cabotegravir (CAB LA), for HIV prevention.
The randomized, controlled, double-blind study found that cabotegravir was 69% more effective (95% CI 41%-84%) in preventing HIV acquisition in men who have sex with men (MSM) and transgender women who have sex with men when compared to the current standard of care, daily oral emtricitabine/tenofovir disoproxil fumarate Read more
Researchers from the Yerkes National Primate Research Center have shown Zika virus infection soon after birth leads to long-term brain and behavior problems, including persistent socioemotional, cognitive and motor deficits, as well as abnormalities in brain structure and function. This study is one of the first to shed light on potential long-term effects of Zika infection after birth.
“Researchers have shown the devastating damage Zika virus causes to a fetus, but we had questions about Read more
The grant will allow Childrenâ€™s and Emory to expand their research partnership, attract top scientists, and advance research discoveries that will improve the health of children.
Some of the pediatric research conducted in a new building to be built on the Emory campus will focus on cardiology, cancer, vaccines, and new drug discovery. The grant has implications for the city of Atlanta as a growing research community, building on collaborations among Childrenâ€™s Healthcare, Emory, Georgia Institute of Technology, Morehouse School of Medicine, and others.
Fred Sanfilippo, MD, PhD, executive vice president for health affairs at Emory, and Donna W. Hyland, president and CEO of Children’s Healthcare of Atlanta, explained that the new grant, which is the largest single gift ever to Children’s, will have an enormous impact on the two institutions, building on the strong partnership between Emory and Children’s and leading them to become a major pediatric research hub in the Southeast and the nation. Most importantly, it will help in finding cures for some of the most common and devastating childhood diseases.
This fresh approach to wellness marks a new model of healthcare called predictive health, which focuses on defining and maintaining health rather than treating disease.
The Center for Health Discovery and Well Being collects and analyzes physical, medical and lifestyle histories, and up to 50 different blood and plasma tests to create a personalized health action plan for each participant. Participants also act as research partners, as data from their assessments is used to discover and develop predictive markers of health and well being. Those markers are ultimately used to create health-related interventions. Whatâ€™s more, the center is part of a research partnership between Emory and Georgia Tech called the Emory/Georgia Tech Predictive Health Institute.
Located on the 18th floor of the Medical Office Tower (MOT) at Emory University Hospital Midtown, the center occupies an architecturally innovative atmosphere that includes flowing spaces, soothing colors, and a big city view.
Healthy individuals, including those with well-controlled chronic conditions, may enroll in the Center.
Emory Vaccine Center researcher Cynthia Derdeyn and her colleagues have a new paper in PLOS Pathogens that is a reality check for researchers designing possible HIV vaccines. The results come from a collaboration with the Rwanda Zambia HIV Research Group. (Although the patients in this paper are from Zambia only.)
Red and green depict the parts of the HIV envelope protein that mutated in two patients (185F and 205F) in response to pressure from their immune systems.
Recently there has been some excitement over the discovery of robust neutralizing antibodies in patients.
The bottom line, according to Derdeyn’s team: even if a vaccine succeeds in stimulating antibodies that can neutralize HIV, the virus is still going to mutate furiously and may escape those antibodies. To resist HIV, someone’s immune system may need to have several types of antibodies ready to go, their results suggest.
A companion paper in the same issue of PLOS Pathogens from South African scientists has similarly bracing results.
Over the past twenty years, the research partnership between Emory University and the Georgia Institute of Technology has developed into one of the leading bioengineering and biomedical research and educational programs in the nation. In recent years this partnership has resulted in the development of several pieces of diagnostic and medical-assistant technology, with medical experts on the Emory side working with engineers on the Georgia Tech side.
An example of this collaboration is the El-E robot, designed to perform simple tasks such as opening drawers and retrieving objects. Clinicians at Emoryâ€™s School of Medicine and engineers at Georgia Tech created the 5Â½-foot-tall machine, which glides across the floor on wheels and takes direction from a laser pointer that users can control in a variety of ways, depending on their preferences and capabilities. El-E is no mere toy, however: The machine could help patients with significant motor impairments, such as sufferers of ALS, maintain their independence and help relieve physical and financial burdens faced by caregivers.
Another result of the Emory-Georgia Tech collaboration is DETECT, a portable device capable of detecting the earliest stage of Alzheimer’s disease, mild cognitive impairment, in any environment. DETECT has a helmet device that includes an LCD display in a visor, along with a computer and noise-reduction headphones. DETECT gives the patient a battery of words and pictures to assess cognitive abilitiesâ€”reaction time and memory capabilities. The low-cost test takes approximately 10 minutes. The device was co-developed by emergency medicine physician David Wright, and Michelle LaPlaca, a scientist in the Wallace H. Coulter Department of Biomedical Engineering at Georgia Tech and Emory.
