Estrogen receptor-alpha and -beta coexist in a subpopulation of sensory neurons of female rat dorsal root ganglia.

Immunoreactivities for estrogen receptor-alpha (ER-alpha) and ER-beta are expressed in sensory neurons of the dorsal root ganglia (DRG). It has not been established, however, if the two receptor subtypes coexist in the same neuron. Double-staining…

Developmental and genetic influences upon gender differences in methamphetamine-induced nigrostriatal dopaminergic neurotoxicity.

The gonadal steroid hormone estrogen (E) may play an important role in sex differences in methamphetamine (MA)-induced neurotoxicity of the nigrostriatal dopaminergic (NSDA) system because E can serve as a neuroprotectant in female, but not male,…

Sex differences in extracellular and intracellular calcium-mediated vascular reactivity to vasopressin in rat aorta.

In rat thoracic aorta, contractile responses to arginine vasopressin are two-fold higher in females than in males. To determine the roles of extracellular and intracellular Ca2+ in this sexual dimorphism in vascular function, vascular reactivity and…

Estrogen reduces acute striatal dopamine responses in vivo to the neurotoxin MPP+ in female, but not male rats.

The effects of in vivo estrogen treatment upon MPP(+)-induced dopamine (DA) release were determined using in vivo microdialysis in female and male rats. Ovariectomized female rats were implanted or not with an estrogen pellet (0.1 mg, 17beta…

Gender differences in modulatory effects of tamoxifen upon the nigrostriatal dopaminergic system.

It has been demonstrated that the gonadal steroid hormone estrogen can exert neuroprotective effects upon the nigrostriatal dopaminergic (NSDA) system against methamphetamine (MA)-induced neurotoxicity in female, but not male, mice. In contrast, the…
