Looking ahead to new opioid treatments

NS graduate student Stephanie Foster sees herself one day specializing in addiction psychiatry. When she started her MD/PhD studies at Emory, she sought out neuroscientist David Weinshenker to discuss research projects. She is now examining potential treatments for opiate addiction based on galanin, a neuropeptide found in the brain. Dr. Weinshenker is a faculty member in the MSP and NS programs.

Weinshenker and his colleagues had already been studying galanin in relation to stimulants such as cocaine. Preliminary studies in animals indicate that activating galanin signals might reduce the rewarding effects of opiates, withdrawal symptoms, and relapse-like behavior.

“This was a whole new direction that looked promising,” Foster says. “But first, we have to work out the brain circuitry.”
