Modulation of Renal Blood Flow and Vascular Tone by Neuronal Nitric Oxide Synthase-Derived Nitric Oxide
Nitric oxide (NO) formed via neuronal nitric oxide synthase (nNOS) in renal vasculature and tissues and in the brain plays an important role in controlling renal hemodynamics, renal function, and systemic blood pressure. Activation of parasympathetic nitrergic nerves innervating renal vasculature contributes to vasodilatation in renal arteries and preand postglomerular arterioles, an increase i...

متن کاملNeuronal nitric oxide synthase contributes to the regulation of hematopoiesis.
Nitric oxide (NO) signaling is important for the regulation of hematopoiesis. However, the role of individual NO synthase (NOS) isoforms is unclear. Our results indicate that the neuronal NOS isoform (nNOS) regulates hematopoiesis in vitro and in vivo. nNOS is expressed in adult bone marrow and fetal liver and is enriched in stromal cells. There is a strong correlation between expression of nNO...
متن کاملNitric oxide and choroidal blood flow regulation.
PURPOSE Nitric oxide (NO) has been found to be an endothelial-derived relaxing factor mediating the vasodilatation that results from the stimulation of muscarinic endothelial receptors. It also has been identified as a putative neurotransmitter of parasympathetic origin in choroidal perivascular autonomic fibers. The authors investigated a potential role of NO in choroidal blood flow (ChBF) reg...
متن کاملAttenuation of activity-induced increases in cerebellar blood flow in mice lacking neuronal nitric oxide synthase.
We used mice deficient in neuronal nitric oxide (NO) synthase (nNOS) to specifically investigate the role of neuronal NO in the increase of cerebellar blood flow (BFcrb) produced by neural activation. Crus II, a region of the cerebellar cortex that receives trigeminal sensory afferents, was activated by low-intensity stimulation of the upper lip (5-25 V, 4-16 Hz) in anesthetized mice. BFcrb was...
