Amphetamine-sensitized animals show a sensorimotor gating and neurochemical abnormality similar to that of schizophrenia.
The aim of these studies was to examine whether amphetamine-induced sensitization in rats could be used as an animal model to study the basis of certain abnormalities seen in schizophrenia. Specifically, these experiments examined whether rats subjected to a sensitizing regimen of amphetamine would show the sensorimotor gating and greater amphetamine-induced displacement of radio-raclopride bin...
متن کاملRab11 supports amphetamine-stimulated norepinephrine transporter trafficking.
The norepinephrine transporter (NET) is a presynaptic plasma membrane protein that mediates reuptake of synaptically released norepinephrine. NET is also a major target for medications used for the treatment of depression, attention deficit/hyperactivity disorder, narcolepsy, and obesity. NET is regulated by numerous mechanisms, including catalytic activation and membrane trafficking. Amphetami...
متن کاملMecp2 deficiency disrupts norepinephrine and respiratory systems in mice.
Rett syndrome is a severe X-linked neurological disorder in which most patients have mutations in the methyl-CpG binding protein 2 (MECP2) gene and suffer from bioaminergic deficiencies and life-threatening breathing disturbances. We used in vivo plethysmography, in vitro electrophysiology, neuropharmacology, immunohistochemistry, and biochemistry to characterize the consequences of the MECP2 m...
متن کاملRegulation of the human norepinephrine transporter by cocaine and amphetamine.
Certain antidepressant and psychostimulant drugs block the uptake of norepinephrine from the synaptic cleft by inhibiting norepinephrine transporter (NET) function. The effects of chronic occupation of the NET by these drugs on NET expression are poorly understood. We previously described down-regulation of the NET in cultured cells after continuous exposure to the tricyclic antidepressant desi...
متن کاملMisdiagnosed Pruritus; Formication due to Chronic Amphetamine Abuse
Amphetamine abusers are shown to have significant cognitive impairments as well as delusional disorders. We present a 17-year-old man who was admitted to the toxicology emergency department with amphetamine overdose. Along with the classic signs and symptoms of overdose including mydriasis, tachycardia, hypertension, sweating and severe agitation, his urine toxicology screen test was found to b...
