Can blood from coronavirus survivors save the lives of others?

Donated blood from COVID-19 survivors could be an effective treatment in helping others fight the illness – and should be tested more broadly to see if it can “change the course of this pandemic,” two Emory pathologists say. The idea of using a component of survivors’ donated blood, or “convalescent plasma,” is that antibodies from patients who have recovered can be used in other people to help them defend against coronavirus.

Targeting metastasis through metabolism

Research from Adam Marcus’ and Mala Shanmugam’s labs was published Tuesday in Nature Communications – months after we wrote an article for Winship Cancer Institute’s magazine about it. So here it is again! At your last visit to the dentist, you may have been given a mouth rinse with the antiseptic chlorhexidine. Available over the counter, chlorhexidine is also washed over the skin to prepare someone for surgery. Winship researchers are now looking at chlorhexidine Read more

From Emory scientist to California policy analyst

Don’t call them alternative careers — since most graduate students in the biomedical sciences won’t end up as professors. Since I found a career outside the laboratory myself, I like to keep an eye out for examples of Emory people who have made a similar jump. [Several more in this Emory Magazine feature, which mentions the BEST program, aimed at facilitating that leap.]

Debra Cooper, PhD

After a postdoc in Texas, former Emory neuroscience graduate student Debra Cooper was awarded a California Council on Science and Technology fellowship to work with the California State Senate staff, and is now a policy consultant there. More about her work can also be found at the CCST blog.

Describe your position as policy consultant now. What types of things do you work on? How does your experience in neuroscience/drug abuse research fit in?

As a policy consultant at the California State Senate Office of Research, I function as a bridge between policy and the technical information that informs public policy. A large component of my time is spent translating research and linking it with relevant policies and regulations. I then synthesize this information and disseminate it to the appropriate audiences through memoranda, reports, or presentations. Sometimes this information is used to advise and make recommendations for legislative ideas.

My main assignments deal with human services (i.e., public services provided by governmental organizations) and veterans affairs. As such, not every project that I work on is directly related to neuroscience, but I often find overlap between my assignments and my academic background. For instance, the intersection of mental health and veterans affairs services is an important topic that bridges my backgrounds. Even when I’m working on issues that don’t directly link to mental health, the years that I spent analyzing research and statistics comes in handy when evaluating relevant documents.

Describe your graduate research at Emory.

I had co-advisors while working on my PhD at Emory – Drs. David Weinshenker and Leonard Howell. My dissertation research focused on one question answered with two different model animals: rats (Weinshenker lab) and squirrel monkeys (Howell lab). I was studying the effectiveness of a drug, nepicastat, in reducing rates of relapse to cocaine abuse. Nepicastat blocks an enzyme (dopamine beta-hydoxylase) which is crucial for converting the neurochemical dopamine into the neurochemical norepinephrine. Both of these neurochemicals are involved in responses to cocaine, and we hypothesized that nepicastat could help in regulating these neurochemicals to prevent relapse. Read more

Study: Regular aerobic exercise and prevention of drug abuse relapse

Exercise provides health benefits

Researchers at Emory University and the University of Georgia have received funding from the National Institutes of Health to study the neurobiological mechanisms for how regular aerobic exercise may prevent drug abuse relapse. The grant is for $1.9 million over the next five years.

David Weinshenker, PhD, associate professor of human genetics, Emory School of Medicine, is a co-principal investigator on the project.

David Weinshenker, PhD

“This research will provide new insight into how regular exercise may attenuate drug abuse in humans,” Weinshenker says “More importantly, it may reveal a neural mechanism through which exercise may prevent the relapse into drug-seeking behavior.”

During the study, Weinshenker and UGA co-investigator Philip Holmes, professor of psychology in the Franklin College of Arts and Sciences, will measure exercise-induced increases of the galanin gene activity in the rat brain.
