We investigated the role of metabotropic glutamate receptor type 5 (mGluR5) in methamphetamine-induced behavioral sensitization. The mGluR5 positive allosteric modulator (3-cyano-N-(1,3-diphenyl-1H-pyrazol-5-yl) benzamide (CDPPB) and negative allosteric modulator fenobam were tested in separate experiments. Sprague-Dawley rats were repeatedly injected with 1 mg/kg methamphetamine or saline, and...
The catastrophic effects of opioids use on public health and the economy are documented clearly in numerous studies. Repeated morphine administration can lead to either a decrease (tolerance) or an increase (sensitization) in its behavioral and rewarding effects. Morphine-induced sensitization is a major problem and plays an important role in abuse of the opioid drugs. Studies reported that mor...
Repeated exposures to stress sensitize motor and addictive effects of drugs of abuse. Recently, it has been shown that stress-induced behavioral sensitization depends on the secretion of glucocorticoids. We investigated if sensitization of dopamine-dependent effects of psychostimulants and opioids was influenced by glucocorticoid. Sensitization of the dopaminergic response to drugs is considere...
The current studies examined the role of medial prefrontal cortical (mPFC) group II metabotropic glutamate receptors (mGluR2/3) in the development of cocaine sensitization. Initial studies demonstrated that intra-mPFC injection of the mGluR2/3 receptor agonist, APDC, dose-dependently reduced acute behavioral response to cocaine (0.015-15 nmol/side with significant effects starting at 1.5nmol/si...
