Modulation of serotonergic neurotransmission by nitric oxide.
Nitric oxide (NO) and serotonin (5-HT) are two neurotransmitters with important roles in neuromodulation and synaptic plasticity. There is substantial evidence for a morphological and functional overlap between these two neurotransmitter systems, in particular the modulation of 5-HT function by NO. Here we demonstrate for the first time the modulation of an identified serotonergic synapse by NO...
متن کاملNitric oxide modulates microvascular permeability.
We recently demonstrated that inhibitors of nitric oxide (NO) production cause a dramatic increase in leukocyte adherence and emigration in postcapillary venules. The objective of this study was to assess whether inhibition of NO production leads to vascular protein leakage and increased microvascular permeability in feline small intestine and to determine whether adherent leukocytes contribute...
متن کاملNitric Oxide Modulates Coronary Autoregulation
were performed in an attempt to reduce the metabolic stimulus to coronary vasomotion and keep it constant. We measured the responses of coronary flow and oxygen metabolism to stepwise changes of the perfusion pressure over the range between 18 and 85 mm Hg. The hearts exhibited autoregulation between 25 and 55 mm Hg and active vasodilation at perfusion pressures above that range. Perfusion with...
متن کاملNitric oxide in the nucleus raphe magnus modulates cutaneous blood flow in rats during hypothermia
Objective(s): Nucleus Raphe Magnus (NRM) that is involved in the regulation of body temperature contains nitric oxide (NO) synthase. Considering the effect of NO on skin blood flow control, in this study, we assessed its thermoregulatory role within the raphe magnus. Materials and Methods: To this end, tail blood flow of male Wistar rats was measured by laser doppler following the induction of ...
متن کاملEndothelial nitric oxide synthase is predominantly involved in Angiotensin II modulation of renal vascular resistance and norepinephrine release Short title NO modulates renal sympathetic neurotransmission
NO is mainly generated by endothelial nitric oxide synthase (eNOS) or neuronal nitric oxide synthase (nNOS). Recent studies indicate that Ang II generates NO release, which modulates renal vascular resistance and sympathetic neurotransmission. Experiments in wild-type [eNOS(+/+) and nNOS(+/+)], eNOS deficient [eNOS(-/-)] and nNOS decficient [nNOS(-/-)] mice were performed to determine which NOS...
