Molecular Alterations of DNA Contribute to Persistence of Memory

November 2011
In a new series of studies tracing the molecular events that occur in the brain as memories are formed and preserved, researchers find that certain epigenetic changes may promote vulnerability to relapse.

N-Acetylcysteine Postsynaptic Effect Limits Efficacy

January 2013

Clinical trials of N-acetylcysteine to help people recovering from drug abuse avoid relapse have demonstrated only moderate efficacy. New NIDA-supported research shows that while a low dose of the medication activates receptors associated with lowered drug-seeking behavior, a higher dose appears to activate receptors associated with increased drug-seeking behavior. The result suggests that a medication or combination of medications that stimulate the receptor GluR2/3 and block mGluR5 may work better than N-acetylcysteine alone.
