Transient hypercapnic stress causes exaggerated and prolonged elevation of cardiac and renal interstitial norepinephrine levels in conscious hypertensive rats.
The responses of sympathetic nerve activity to transient stress can be exaggerated in salt-sensitive (SS), hypertensive subjects. Cardiac and renal interstitial norepinephrine (iNE) levels during and after transient hypercapnia were investigated in conscious SS rats. Dahl SS and salt-resistant (SR) 6-wk-old rats were fed a high-salt diet, and at 12 wk iNE levels in the heart and kidney were det...
متن کاملNeuroanatomy of Stress Responses
The autonomic nervous system, especially the sympathetic nervous system, regulates immune responses, while cytokines produced in the immune system also affect neuronal activities. Stress-induced expression of immediate early genes, such as c-Fos in the brain, and the viral transneuronal labeling using pseudorabies virus make it possible to analyze the neurocircuitry of the stress-related centra...
متن کاملThe Drosophila inebriated-encoded neurotransmitter/osmolyte transporter: dual roles in the control of neuronal excitability and the osmotic stress response.
Water reabsorption by organs such as the mammalian kidney and insect Malpighian tubule/hindgut requires a region of hypertonicity within the organ. To balance the high extracellular osmolarity, cells within these regions accumulate small organic molecules called osmolytes. These osmolytes can accumulate to a high level without toxic effects on cellular processes. Here we provide evidence consis...
متن کاملOxidative stress in the context of acute cerebrovascular stroke.
BACKGROUND AND PURPOSE Free radical generation and consequent oxidative stress in thrombotic cerebrovascular stroke have a distinctive role in the pathogenesis of ischemic brain injury. One of the potential injurious effects of homocyst(e)ine in occlusive vascular diseases is free radical generation. In the current study, we investigated the status of oxidant stress in the acute phase of thromb...
متن کاملHypothalamo-Sympathetic Modulation of Splenic Natural Killer Cell Activity: An Involvement of Brain Cytokines
The sympathetic nervous system is one of the multiple channels that communicate between brain and immune system. In the brain-immune interactions, cytokines produced in the periphery and brain during inflammatory as well as noninflammatory stress play important roles as signal molecules. For example, central administration of interleukin-1 (IL-1 ) and interferon(IFN) suppresses splenic natural ...
