UIC research identifies potential pathways to treating alcohol use disorder, depression

Researchers at UIC's Center for Alcohol Research in Epigenetics have discovered a key regulator of gene expression and anhedonia during alcohol withdrawal. Blocking STAT3 activity alleviates withdrawal-induced depression in rats, and similar results are seen in human postmortem hippocampus samples of individuals with alcohol use disorder.
