1. Inervação noradrenérgica na ativação da glândula de veneno da serpente Bothrops jararaca. / Noradrenergic innervation in activation of venom gland of Bothrops jararaca snake.
Neste trabalho, mostramos que a extração de veneno promove aumento na ativação dos fatores de transcrição NFkB e AP-1. Noradrenalina, liberada após extração de veneno, é responsável por esse aumento. A estimulação dos adrenoceptores a e b estão envolvidos nessa resposta, entretanto, o

2. Pulmonary noradrenergic innervation of rat and monkey: a comparative study
El-Bermani, Al-Walid I. (1978).Thorax, 33, 167-174. Pulmonary noradrenergic innervation of rat and monkey: a comparative study. The noradrenergic innervation of rat and monkey lungs was studied using the fluorescence histochemical method for norepinephrine of Falck (1962). In both species the noradrenergic nerves enter the lung at the hilum in association wi

3. Noradrenergic and serotonergic fibers innervate complementary layers in monkey primary visual cortex: an immunohistochemical study.
Antisera directed against human dopamine beta-hydroxylase or serotonin were used to characterize the noradrenergic and serotonergic innervation patterns within the primary visual cortex of the squirrel monkey. The noradrenergic and serotonergic projections exhibit a high degree of laminar complementarity: layers V and VI receive a dense noradrenergic project

4. Blood--brain barrier sodium/potassium pump: modulation by central noradrenergic innervation.
The active transport of Na+ and K+ across the blood--brain barrier by the membrane-bound enzyme Na+/K+-activated ATPase of brain microvessel endothelial cells has a major role in the maintenance of brain water and electrolyte homeostasis. To test whether the putative noradrenergic innervation of cerebral microvessels from the nucleus locus ceruleus contribut

5. Innervation of arteriovenous anastomoses in the web of the foot of the domestic duck, Anas platyrhynchos: structural evidence for the presence of non-adrenergic non-cholinergic nerves.
An analysis of the innervation of arteriovenous anastomoses in the web of the foot of the Pekin Duck (Anas platyrhynchos) was compared with the innervation of the right atrium of the duck heart using histochemical, ultrastructural and morphometric techniques, before and after 6OHDA. The presence of intense catecholamine fluorescence and nerve terminals conta

6. Grafted noradrenergic neurons suppress seizure development in kindling-induced epilepsy.
Norepinephrine-rich cell suspensions, prepared from the locus coeruleus region of rat fetuses, were grafted bilaterally into the hippocampus of rats made hypersensitive to hippocampal kindling by a neurotoxic lesion of the central catecholamine system. The animals with grafts showed a marked suppression of the onset and progression of kindling-induced epilep

7. Electrophysiology and innervation of the smooth muscle of dog inferior vena cava.
1. Electrical properties of outer and inner muscles of three portions of dog inferior vena cava and their catecholaminergic innervation were investigated by microelectrode recording and an immunohistochemical technique. 2. There was no difference in the electrical properties of outer and inner muscles of the supradiaphragmatic (portion a) or the infrarenal (

8. Reduced sympathetic innervation after alteration of target cell neurotransmitter phenotype in transgenic mice.
Neurotransmitters play a variety of important roles during nervous system development. In the present study, we hypothesized that neurotransmitter phenotype of both projecting and target cells is an important factor for the final synaptic linkage and its specificity. To test this hypothesis, we used transgenic techniques to convert serotonin/melatonin-produc

9. Noradrenergic parenchymal nerve fiber branching after cold acclimatisation correlates with brown adipocyte density in mouse adipose organ
The mammalian adipose organ is composed of subcutaneous and visceral depots containing white and brown adipocytes. Cold acclimatisation induces an increase in the brown component without affecting the overall number of adipocytes; this form of plasticity is associated to obesity and diabetes resistance in experimental models. Cold activates the drive of the

10. Neurone-specific enolase and S-100: new markers for delineating the innervation of the respiratory tract in man and other mammals.
Lung innervation has been studied in the past by methylene blue staining and silver impregnation and more recently by histochemical methods. These techniques give only a partial picture of the total innervation. We have delineated the innervation of the lung in man and three other mammalian species by immunostaining with antibodies to two new markers of nerv

11. Leukemia inhibitory factor induces neurotransmitter switching in transgenic mice.
Leukemia inhibitory factor (LIF) is a cytokine growth factor that induces rat sympathetic neurons to switch their neurotransmitter phenotype from noradrenergic to cholinergic in vitro. To test whether LIF can influence neuronal differentiation in vivo, we generated transgenic mice that expressed LIF in pancreatic islets under the control of the insulin promo

12. Noradrenergic Regulation of GABAergic Inhibition of Main Olfactory Bulb Mitral Cells Varies as a Function of Concentration and Receptor Subtype
The main olfactory bulb (MOB) receives a rich noradrenergic innervation from the pontine nucleus locus coeruleus (LC). Previous studies indicate that norepinephrine (NE) modulates the strength of GABAergic inhibition in MOB. However, the nature of this modulation and the NE receptors involved remain controversial. The goal of this study was to investigate th
