New research reveals that the enzyme HDAC5 plays a critical role in suppressing a gene (Scn4b) that regulates brain activity associated with drug-related memories, which are central to relapse in substance use disorders (SUDs). By limiting expression of Scn4b, HDAC5 reduces the excitability of neurons in the brain's reward system, weakening the formation of powerful drug-environment associations.
