In a paper published in the latest issue of the neuroscience journal Neuron, McLean Hospital investigators report that a gene essential for normal brain development, and previously linked to Autism Spectrum Disorders, also plays a critical role in addiction-related behaviors.
"In our lab, we investigate the brain mechanisms behind drug addiction -- a common and devastating disease with limited treatment options," explained Christopher Cowan, PhD, director of the Integrated Neurobiology Laboratory at McLean and an associate professor of Psychiatry at Harvard Medical School. "Chronic exposure to drugs of abuse causes changes in the brain that could underlie the transition from casual drug use to addiction. By discovering the brain molecules that control the development of drug addiction, we hope to identify new treatment approaches."
