Effects of Stress and MDMA on Hippocampal Gene Expression

BioMed Research International 2014 Georg F. Weber, Bethann N. Johnson, Bryan K. Yamamoto et al. 19 citations

MDMA (3,4-methylenedioxymethamphetamine) is a substituted amphetamine and popular drug of abuse. Its mood-enhancing short-term effects may prompt its consumption under stress. Clinical studies indicate that MDMA treatment may mitigate the symptoms of stress disorders such as posttraumatic stress syndrome (PTSD). On the other hand, repeated administration of MDMA results in persistent deficits...

Chronic Stress Enhances the Corticosterone Response and Neurotoxicity to +3,4-Methylenedioxymethamphetamine (MDMA): The Role of Ambient Temperature

Journal of Pharmacology and Experimental Therapeutics July 16, 2010 Bethann N. Johnson, Bryan K. Yamamoto 22 citations

Stress facilitates drug abuse by humans. In rodents, stress enhances the neurochemical, neuroendocrine, and behavioral responses to psychostimulants. Although chronic unpredictable stress (CUS) enhances the acute hyperthermic and long-term monoamine-depleting effects of the psychostimulant +3,4-methylenedioxymethamphetamine (MDMA), the roles of hyperthermia and corticosterone (CORT) in...
