- 17β-Estradiol alters the response of subfornical organ neurons that project to supraoptic nucleus to plasma angiotensin II and hypernatremia.
- Ciriello J, Roder S.Author information Department of Physiology and Pharmacology, Schulich School of Medicine and Dentistry, University of Western Ontario, London, Ontario, Canada. john.ciriello@schulich.uwo.caAbstractThis study was done in urethane anesthetized, ovariectomized (OVX) female rats that were either implanted or not implanted with silastic capsules containing17β-estradiol (E2) to investigate the effect of systemic changes in E2 on the discharge rate of subfornical organ (SFO) neurons that projected to supraoptic nucleus (SON) and responded to changes in plasma levels of angiotensin II (ANG II) or hypernatremia. Extracellular single unit recordings were made from 146 histologically verified single units in SFO. Intra-carotid infusions of ANG II excited ~57% of these neurons, whereas ~23% were excited by hypertonic NaCl. Basal discharge rate of neurons excited by ANG II or hypertonic NaCl was significantly lower in OVX+E2 rats compared to OVX only animals. The response of SFO neurons antidromically activated by SON stimulation to intra-carotid injections of ANG II or hypertonic NaCl was greater in the OVX only compared to the OVX+E2 rats. Intra-carotid injections of E2 in either group attenuated not only the basal discharge of these neurons, but also their response to ANG II or hypertonic NaCl. In all cases this inhibitory effect of E2 was blocked by an intra-carotid injection of the E2 receptor antagonist ICI-182780, although ICI-182780 did not alter the neuron's response to ANG II or hypertonic NaCl. Additionally, ICI-182780 in the OVX+E2 animals significantly raised the basal discharge of SFO neurons and their response to ANG II or hypertonic NaCl. These data indicate that E2 alters the response of SFO neurons to ANG II or NaCl that project to SON, and suggest that E2 functions in the female to regulate neurohypophyseal function in response to circulating ANG II and plasma hypernatremia.

- Exposure to female pheromones stimulates a specific type of neuronal population in the male but not female magnocellular division of the medial preoptic nucleus (MPN mag) of the Syrian hamster.
- Swann JM, Richendrfer HA, Dawson L, Nack E, Whylings J, Garelick T.Author information Lehigh University, Dept of Biological Sciences, United States. Electronic address: jms5@lehigh.edu.AbstractThe magnocellular division of the medial preoptic area (MPN mag) integrates pheromonal and hormonal signals to play a critical role in the expression of male typical sex behavior. The MPN mag contains two morphologically distinct neuronal populations; the percentage of each type within the nucleus is sex specific. Males have more neurons with a single nucleolus whereas females have more with multiple nucleoli. To determine which neuronal subtype mediates pheromonal induction of copulation, tissue from male and female hamsters exposed to female pheromones was immunolabeled for the immediate early protein (EGR-1). Subsequently the tissue was counterstained and the number of ERG-1 neurons with one or two nuclei was determined. The results indicate that pheromones stimulate neurons with single nucleoli in males but fail to stimulate either neuronal subtype in females suggesting that synaptic input to the MPN mag is sexually differentiated.

- The medial habenula contains a specific nonstellate subtype of astrocyte expressing the ectonucleotidase NTPDase2.
- Gampe K, Hammer K, Kittel Á, Zimmermann H.Author information Institute of Cell Biology and Neuroscience, Biologicum, Goethe-University, Frankfurt, Germany. k.gampe@bio.uni-frankfurt.deAbstractATP-mediated synaptic transmission represents the only transmitter-gated Ca(2+)-entry pathway in neurons of the rodent medial habenula. In addition to direct purinergic receptor-mediated synaptic inputs, the medial habenula contains purinergic systems that modulate synaptic transmission. Purinergic signaling is modulated or terminated by ectonucleotidase, nucleotide-hydrolyzing enzymes of the cell surface. Here we identify the major ectonucleotidase responsible for the hydrolysis of extracellular ATP in the mouse medial habenula as ectonucleoside triphosphate diphosphohydrolase 2 (NTPDase2), using immunostaining and enzyme histochemistry. Double labeling experiments reveal that the enzyme is expressed by astrocytes enwrapping the densely packed neurons and also the myelinated fiber bundles of the stria medullaris. NTPDase2 immunoreactivity is absent from the lateral habenula. The analysis of mice expressing enhanced green fluorescent protein under the promoter of glial fibrillary acidic protein revealed that the medial habenula harbors a highly polar type of astrocytes with very long laminar cellular processes, untypical for grey matter astrocytes. Its morphology strongly differs from that of the stellate astrocytes in the adjacent lateral habenula. Our results suggest that the mouse medial habenula contains a specific perineuronal nonstellate subtype of astrocyte that expresses the ectonucleotidase NTPDase2 and is in a strategic position to modulate purinergic transmission in this subnucleus.
