Abstract

Estrogens affect dopamine transmission in the striatum, increasing dopamine availability, maintaining D2 receptor density, and reducing the availability of the dopamine transporter. Some of these effects of estrogens are rapid, suggesting that they are mediated by membrane associated receptors. Recently our group demonstrated that there is extra-nuclear labeling for ERa, ERß, and GPER1 in the striatum, but that ERa and GPER1 are not localized to dopaminergic neurons in this region. GABAergic neurons are the most common type of neuron in the striatum, and changes in GABA transmission affect dopamine transmission. Thus, to determine whether ERa or GPER1 are localized to GABAergic neurons, we double labeled the striatum with antibodies for ERa or GPER1 and GABA and examined them using electron microscopy. Ultrastructural analysis revealed that ERa and GPER1 are localized exclusively to extranuclear sites in the striatum, and ~35% of the dendrites and axon terminals labeled for these receptors contain GABA immunoreactivity. Binding at membrane-associated ERa and GPER1 could account for rapid estrogen-induced decreases in GABA transmission in the striatum, which, in turn, could affect dopamine transmission in this region.
