Although MDMA (3,4-methylendioxymethamphetamine, ecstasy) neurotoxicity in serotonin neurons is largely recognized in a wide variety of species including man, neurotoxicity in dopamine (DA) neurons is thought to be species-specific. MDMA is mainly consumed by adolescents, often in conjunction with caffeine (Energy Drinks) and this association has been reported to exacerbate MDMA toxic effects....

Background: Previous studies by our group have demonstrated that caffeine, an antagonist of adenosine A 1 and A 2A receptors, amplifies the glial activation induced by 3,4-methylendioxymethamphetamine (MDMA, “ecstasy”) in mice. To elucidate the mechanisms underlying this effect, the present study evaluated whether selective antagonists for the A 1 or the A 2A adenosine receptor had any...

Several studies suggest that 50-kHz ultrasonic vocalizations (USVs) may indicate a positive affective state in rats, and these vocalizations are increasingly being used to investigate the properties of psychoactive drugs. Previous studies, however, have focused on dopaminergic psychostimulants and morphine, whereas little is known about how other drugs modulate 50-kHz USVs. To further elucidate...

ABSTRACT Clinical observations report a greater propensity to develop Parkinson's disease (PD) in amphetamine users. 3,4‐Methylenedioxymethamphetamine (MDMA; “ecstasy”) is an amphetamine‐related drug that is largely consumed by adolescents and young adults, which may have neuroinflammatory and neurotoxic effects. Here, the objective was to evaluate in mice whether consumption of MDMA during...

Abstract Evidence is accumulating to suggest that 3,4‐methylenedioxymethamphetamine ( MDMA ) has neurotoxic and neuroinflammatory properties. MDMA is composed of two enantiomers with different biological activities. In this study, we evaluated the in vivo effects of S(+)‐ MDMA , R(−)‐ MDMA , and S(+)‐ MDMA in combination with R(−)‐ MDMA on microglial and astroglial activation compared with...
