چکیده

Because high doses of methamphetamine promote free radical formation, and striatal dopamine transporters are rapidly inactivated by oxidative events, we determined the effect of a single high dose of methamphetamine on dopamine transporter activity in striatal synaptosomes. One hour after methamphetamine administration, dopamine uptake decreased by 48%. This dramatic decline was totally reversed by 24 h after treatment. These findings suggest that methamphetamine reversibly decreases dopamine transporter activity by oxidative mechanisms.

Methamphetamine-induced rapid and reversible changes in dopamine transporter function: an in vitro model.

This laboratory has demonstrated that a single methamphetamine (METH) injection rapidly and reversibly decreases the activity of the dopamine transporter (DAT), as assessed ex vivo in synaptosomes prepared from treated rats. This decrease does not occur because of residual drug introduced by the original injection or nor is it associated with a change in binding of the DAT ligand WIN35428. The ...

Rapid and reversible effects of methamphetamine on dopamine transporters.

Reactive oxygen species decrease dopamine transporter (DAT) function in vitro. Because of this, and the finding that METH administration causes oxygen radical formation in vivo, the effects of METH administration on DAT activity in rat striatum were investigated. A single METH injection caused a dose-dependent (0-15 mg/kg) decrease in [3H]dopamine uptake into striatal synaptosomes prepared 1 h ...

The evaluation of AZ66, an optimized sigma receptor antagonist, against methamphetamine-induced dopaminergic neurotoxicity and memory impairment in mice.

Sigma (σ) receptors have recently been identified as potential targets for the development of novel therapeutics aimed at mitigating the effects of methamphetamine. Particularly, σ receptors are believed to mitigate some of the neurotoxic effects of methamphetamine through modulation of dopamine, dopamine transporters and body temperature. Furthermore, recent evidence suggests that targeting σ ...

Loss of dopamine transporters in methamphetamine abusers recovers with protracted abstinence.

Methamphetamine is a popular drug of abuse that is neurotoxic to dopamine (DA) terminals when administered to laboratory animals. Studies in methamphetamine abusers have also documented significant loss of DA transporters (used as markers of the DA terminal) that are associated with slower motor function and decreased memory. The extent to which the loss of DA transporters predisposes methamphe...

Role of natural products in mitigation of toxic effects of methamphetamine: A review of in vitro and in vivo studies

Objective: Methamphetamine (METH) increases dopamine, norepinephrine and serotonin concentrations in the synaptic cleft, and induces hyperactivity. The current management of acute METH poisoning relies on supportive care and no specific antidote is available for treatment. The main objective of this review was to present the evidence for effectiveness of the herbal medicine in ...
