Abstract

Methamphetamine (METH) and 3,4-meythylenedioxymethamphetamine (MDMA; 'ecstasy') are currently major drugs of abuse. One of the major concerns of amphetamines abuse is their potential neurotoxic effect on dopaminergic and serotonergic neurons. Although data from human studies are somewhat limited, compelling evidence suggests that these drugs cause neurotoxicity in rodents and primates. Recent studies in transgenic and knockout mice identified the role of dopamine transporters, nitric oxide, apoptotic proteins, and inflammatory cytokines in amphetamines neurotoxicity. Further research into the mechanisms underlying the dopaminergic and serotonergic neurotoxicity and the behavioral corollaries of these neuronal insults could facilitate our understanding of the consequences of human abuse of METH and MDMA on cognition, drug-seeking behavior, extinction and relapse.
