'Master key' microRNA has links to both ASD and schizophrenia

Recent studies of complex brain disorders such as schizophrenia and autism spectrum disorder (ASD) have identified a few "master keys," risk genes that sit at the center of a network of genes important for brain function. Researchers at Emory and the Chinese Academy of Sciences have created mice partially lacking one of those master keys, called MIR-137, and have used them to identify an angle on potential treatments for ASD. The results were published this Read more

Explainer: the locus coeruleus

The locus coeruleus is a part of the brain that has been getting a lot of attention recently from Emory neuroscience researchers.

The locus coeruleus is the biggest source of the neurotransmitter norepinephrine in the brain. Located deep in the brainstem, it has connections all over the brain, and is thought to be involved in arousal and attention, stress, memory, the sleep-wake cycle and balance.

Researchers interested in neurodegenerative disease want to look at the locus coeruleus because it may be one of the first structures to degenerate in diseases such as Alzheimer’s and Parkinson’s. In particular, the influential studies of German neuro-anatomist Heiko Braak highlight the locus coeruleus as a key “canary in the coal mine” indicator of neurodegeneration.

That’s why neurologist Dan Huddleston, working with biomedical imaging specialists Xiangchuan Chen and Xiaoping Hu and colleagues at Emory, has been developing a method for estimating the volume of the locus coeruleus by magnetic resonance imaging (MRI). Their procedure uses MRI tuned in such a way to detect the pigment neuromelanin (see panel), which accumulate in both the locus coeruleus and in the substantia nigra. Read more

GRA partnership promotes research collaboration, grows economy

“Other states wish they had what Georgia has: Research universities that work together, and a unified commitment from industry, government and academia to grow a technology-based economy,” states Michael Cassidy, president and CEO of the Georgia Research Alliance (GRA) in the GRA’s recent annual report.”

As one of six GRA universities, Emory has benefited from this unique partnership in numerous ways: through its 11 Eminent Scholars, multidisciplinary university and industry collaborations, and support for research in vaccines, nanomedicine, transplantation, neurosciences, pediatrics, biomedical engineering, clinical research, and drug discovery.

Emory is featured throughout the report, including

  • The Wallace H. Coulter Department of Biomedical Engineering at Georgia Tech and Emory and its four eminent scholars, Xiaoping Hu, PhD, Eberhard Voit, PhD, Barbara Boyan, PhD and Don Giddens, PhD.
  • Emory transplant medicine expert and GRA Eminent Scholar Allan Kirk, MD, PhD, who collaborates with Andrew Mellor, PhD at the Medical College of Georgia on research to find enzymes that could keep the body from rejecting newly transplanted organs.
  • The Emory-University of Georgia Influenza Center of Excellence and its leading collaborators, GRA Eminent Scholar and Emory Vaccine Center Director Rafi Ahmed, PhD, and Emory microbiologist Richard Compans, PhD, along with UGA GRA Eminent Scholar Ralph Tripp.

Biomedical engineering links Emory, Georgia Tech in medical discoveries

Larry McIntire, PhD

Despite its youth, the 20-year-old field of biomedical engineering is the fastest growing engineering academic program today. The joint Wallace H. Coulter Department of Biomedical Engineering at Georgia Tech and Emory, with Larry McIntire as chair, has emerged on the forefront of biotechnology-related research and education.

“By integrating the fields of life sciences with engineering,” McIntire explains, “we can better understand the mechanisms of disease and develop new ways to diagnose and treat medical problems. We are working collaboratively in the fields of biomedical nanotechnology, predictive health, regenerative medicine, and health care robotics, among others.
