Colon dysregulation in methamphetamine self-administering HIV-1 transgenic rats
The integrity and function of the gut is impaired in HIV-infected individuals, and gut pathogenesis may play a role in several HIV-associated disorders. Methamphetamine is a popular illicit drug abused by HIV-infected individuals. However, the effect of methamphetamine on the gut and its potential to exacerbate HIV-associated gut pathology is not known. To shed light on this scenario, we evalua...
متن کاملExtended access to methamphetamine self-administration up-regulates dopamine transporter levels 72 hours after withdrawal in rats.
Previous studies have demonstrated that there are persistent changes in dopamine systems following withdrawal from methamphetamine (METH). This study examined changes in striatal dopamine transporter (DAT), tyrosine hydroxylase (TH) and dopamine receptor 2 (D2) 72 h after withdrawal from METH intravenous self- administration (IVSA). Rats were given limited (1h) or extended (6h) access to METH I...
متن کاملLobeline attenuates d-methamphetamine self-administration in rats.
alpha-Lobeline inhibits d-amphetamine-evoked dopamine release from striatal slices in vitro, appearing to reduce the cytosolic pool of dopamine available for reverse transport by the dopamine transporter. Based on this neurochemical mechanism of action, the present study determined if lobeline decreases d-methamphetamine self-administration. Rats were surgically implanted with jugular catheters...
متن کاملBupropion attenuates methamphetamine self-administration in adult male rats.
Bupropion is a promising candidate medication for methamphetamine use disorder. As such, we used a preclinical model of drug-taking to determine the effects of bupropion on the reinforcing effects of methamphetamine (0.025, 0.05 or 0.1 mg/kg/infusion). Specificity was determined by investigating the effects of bupropion on responding maintained by sucrose. In the self-administration study, rats...
