Transcription Factor CREB3L1 Regulates Vasopressin Gene Expression in the Rat Hypothalamus
(Journal of Neuroscience, 2014-03-12) [Artigo]
Arginine vasopressin (AVP) is a neurohypophysial hormone regulating hydromineral homeostasis. Here we show that the mRNA encoding cAMP responsive element-binding protein-3 like-1 (CREB3L1), a transcription factor of the ...
Cardiovascular responses produced by central injection of hydrogen peroxide in conscious rats
(Brain Research Bulletin, 2006-12-11) [Artigo]
Reactive oxygen species (ROS) have been shown to modulate neuronal synaptic transmission and may play a role on the autonomic control of the cardiovascular system. In this study we investigated the effects produced by ...
Involvement of the median preoptic nucleus in blood pressure control
(Neuroscience Letters, 2014-01-13) [Artigo]
Studies have demonstrated that median preoptic nucleus (MnPO) neurons play a role in organizing the cardiovascular responses induced by changes in the circulating blood volume. The present study examined whether the MnPO ...
Effects of acetylcholine and cholinergic antagonists on the activity of nucleus of the solitary tract (NTS) neurons
(FASEB Journal, 2013-04-01) [Resumo]
Swimming Exercise Changes Hemodynamic Responses Evoked by Blockade of Excitatory Amino Receptors in the Rostral Ventrolateral Medulla in Spontaneously Hypertensive Rats
(BioMed Research International, 2014-01-01) [Artigo]
Exercise training reduces sympathetic activity in hypertensive humans and rats. We hypothesized that the swimming exercisewould change the neurotransmission in the rostral ventrolateral medulla (RVLM), a key region involved ...
Antihypertensive responses elicited by central moxonidine in rats: Possible role of nitric oxide
(Journal of Cardiovascular Pharmacology, 2006-06-01) [Artigo]
In the present study, we investigated the effects of pretreatment with N-G-nitro-L-arginine methyl ester (L-NAME) (nitric oxide synthase inhibitor) injected intravenously (IV) on the hypotension, bradycardia, and vasodilation ...
The bradycardic and hypotensive responses to serotonin are reduced by activation of GABA A receptors in the nucleus tractus solitarius of awake rats
(Brazilian Journal of Medical and Biological Research, 2005-07-01) [Artigo]
We investigated the effects of bilateral injections of the GABA receptor agonists muscimol (GABA A) and baclofen (GABA B) into the nucleus tractus solitarius (NTS) on the bradycardia and hypotension induced by iv serotonin ...
Lesions of the commissural subnucleus of the nucleus of the solitary tract increase isoproterenol-induced water intake
(Brazilian Journal of Medical and Biological Research, 2007-08-01) [Artigo]
The nucleus of the solitary tract (NTS) is the primary site of the cardiovascular afferent information about arterial blood pressure and volume. The NTS projects to areas in the central nervous system involved in cardiovascular ...
Vasopressin-dependent pressor responses induced by hypertonic saline load in rats with commissural NTS lesions
(FASEB Journal, 2007-04-01) [Resumo]
