Medications that target norepinephrine (NE) neurotransmission alter the behavioral effects of cocaine and may be beneficial for stimulant-use disorders. We showed previously that the short-acting, α1-adrenergic antagonist, prazosin, blocked drug-induced reinstatement of cocaine-seeking in rats and doxazosin (DOX), a longer-acting α1 antagonist blocked cocaine's subjective effects in cocaine-dep...
BACKGROUND Several of the behavioral effects of amphetamine (AMPH) are mediated by an increase in dopamine neurotransmission in the nucleus accumbens. However, evidence shows that γ-aminobutyric acid B (GABAB) receptors are involved in the behavioral effects of psychostimulants, including AMPH. Here, we examined the effects of co-administration of the GABAB receptor agonist baclofen and a posit...
BACKGROUND Sickle cell disease (SCD) is associated with both acute vaso-occlusive painful events as well as chronic pain syndromes, including heightened sensitivity to touch. We have previously shown that mice with severe SCD (HbSS mice; express 100% human sickle hemoglobin in red blood cells; RBCs) have sensitized nociceptors, which contribute to increased mechanical sensitivity. Yet, the hype...
Cocaine-induced endocannabinoid release modulates behavioral and neurochemical sensitization in mice
CB1 receptor antagonists have been shown to prevent acute and long-term behavioral effects of cocaine. Here we evaluate the effectiveness of the CB1 receptor antagonist rimonabant to modify sensitized responses to cocaine. Mice were treated with saline or cocaine injections in a 15-day intermittent sensitization treatment and subsequently treated with either vehicle, 1 or 10mg/kg rimonabant in ...
