Estradiol Selectively Regulates a,,-Noradrenergic Receptors in Hypothalamus and Preoptic Area
We previously demonstrated that estradiol administered in viva elevates the number of a,-adrenoceptors in preoptic area (POA) and hypothalamic membranes from ovariectomized female rats and potentiates a, receptor augmentation of ,&adrenoceptor-stimulated CAMP formation in slices from these brain regions. Present studies examined (1) if estradiol selectively regulates any cY,-adrenoceptor subtyp...
متن کاملDopamine activates noradrenergic receptors in the preoptic area.
Dopamine (DA) facilitates male sexual behavior and modulates aromatase activity in the quail preoptic area (POA). Aromatase neurons in the POA receive dopaminergic inputs, but the anatomical substrate that mediates the behavioral and endocrine effects of DA is poorly understood. Intracellular recordings showed that 100 microm DA hyperpolarizes most neurons in the medial preoptic nucleus (80%) b...
متن کاملEstrogen and progestin receptors appear in transplanted fetal hypothalamus-preoptic area independently of the steroid environment.
Sexual maturation and differentiation of the rat brain are believed to result from the interaction of gonadal steroids with specific neural receptors during late fetal and early postnatal life. A variety of evidence indicates that the first appearance of estrogen receptors in the hypothalamus-preoptic area (HPOA) during the perinatal period is a crucial evident underlying these processes. Howev...
متن کاملEstradiol-sensitive projection neurons in the female rat preoptic area
Electrical stimulation of the preoptic area (POA) interrupts the lordosis reflex, a combined contraction of back muscles, in response to male mounts and the major receptive component of sexual behavior in female rat in estrus, without interfering with the proceptive component of this behavior or solicitation. Axon-sparing POA lesions with an excitotoxin, on the other hand, enhance lordosis and ...
متن کاملEstrogen receptor alpha expression in the medial preoptic area and the medial basal hypothalamus under different physiological conditions in cattle.
The distribution and morphology of immunoreactive estrogen receptor alpha (ERalpha)- containing cells were examined in the cattle brain. The brains were collected from two cows and a male calf. One of the cows was sacrificed one week after parturition. ERalpha expressions in the preoptic area of the rostral forebrain and the medial basal hypothalamic area were evaluated immunohistochemically us...
