Depletion of dopamine (DA) reduces D, receptor number, but D-3 receptor expression is also regulated by brain-derived neurotrophic factor (BDNF). We took advantage of transgenic heterozygous BDNF mutant mice (+/-) to determine if reduced BDNF and…

Mate mice were reported to display greater methamphetamine-induced neurotoxicity than females. The present study evaluated the involvement of phosphatidylinositol-3 kinase (PI3K)/Akt and extracellular signal-regulated kinase (ERK1/2) pathways in this…

Studies with the 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) animal model of Parkinson's disease have shown the ability of 17 beta-estradiol to protect the nigrostriatal dopaminergic system. This paper reviews the signaling pathways mediating…

Eight male rats previously trained to discriminate 2.0 mg/kg N-ethyl-3,4-methylenedioxyamphetamine (MDE) from its vehicle in a two-lever, food motivated task were utilized to characterize the stimulus properties of MDE. The 5-HT receptor agonists…

We investigated the hypothesis that neural stem cells (NSCs) possess an intrinsic capacity to "rescue" dysfunctional neurons in the brains of aged mice. The study focused on a neuronal cell type with stereotypical projections that is commonly…

Male C57/B1 mice received bilateral intranasal infusions of saline, MPTP or an intraperitoneal injection of MPTP. Infusions were performed using a peristaltic pump at a setting of 100 microliters/min. The MPTP, diluted in saline at concentrations of…

Male mice treated with MPTP or vehicle were tested for their ability to demonstrate a memory-recognition response as evaluated in a habituation-dishabituation task. Treatment with MPTP severely disrupted the male's habituation-dishabituation response…

Male retired breeder C57/Bl and CD-1 mice were treated with either MPTP or its vehicle. At 7-10 days post-treatment, catecholamine concentrations within the olfactory bulbs (OB) and hypothalamus were determined. Norepinephrine concentrations within…
