Nitric oxide, nitric oxide synthase, and hypertensive vascular disease
Current Hypertension Reports, 1999In normotension the endothelium produces mainly nitric oxide (NO) and prostacyclin, and the vasodilator and growth inhibitory influence predominates. Hypertension, however, is associated with a shift towards enhanced constriction and vascular hypertrophy.

Mitochondrial nitric oxide synthase
Mitochondrion, 2004Nitric oxide (NO*) can bind to and inhibit the terminal enzyme of the mitochondrial respiratory chain, cytochrome c oxidase (complex IV). In vivo, NO* is made by the NO* synthase (NOS) family of enzymes, and considerable debate has recently arisen regarding a NOS inside mitochondria (termed 'mtNOS').

Nitric Oxide Synthase Expression and Nitric Oxide Toxicity in Oligodendrocytes
Antioxidants & Redox Signaling, 2006Oligodendrocytes (OLG) have more complex interactions with nitric oxide (NO) than initially suspected. Historically, OLG were seen only as targets of high NO levels released from other cells. Expression of nitric oxide synthase type II (NOS-2) in primary cultures of OLGs stimulated by cytokines led to controversy due to the presence of small numbers of

Inducible nitric oxide synthase and nitric oxide production by oligodendrocytes
Journal of Neuroscience Research, 1997It has been previously demonstrated that microglia and astrocytes produce micromolar amounts of nitric oxide in vitro. In this study, we demonstrate that primary rat oligodendrocytes can be stimulated to produce iNOS mRNA as detected by Northern blot and in situ hybridization analysis and a 131-kDa iNOS protein by Western blot analysis; protein was ...

Current Protocols in Pharmacology, 1998
AbstractNitric oxide (NO) is a widespread messenger molecule that regulates cardiovascular tone, immune responses, and neuronal function. This unit provides a simple protocol for measuring NO production based on the stoichiometric formation of the byproduct L‐citrulline by nitric oxide synthase (NOS) when NO is produced.

Nitric Oxide Synthase Inhibitors
2003In 1990, several studies reported that an enhanced formation of endogenous nitric oxide (NO) contributes to the hypotension caused by endotoxin and tumor-necrosis factor-α (TNFα) (1-3). In addition, it became apparent that this overproduction of NO also plays an important role in the pathophysiology of the vascular hyporesponsiveness to vasoconstrictor

Immunobiology of Nitric Oxide and Regulation of Inducible Nitric Oxide Synthase
2017Nitric oxide (NO) is a bioactive gas that has multiple roles in innate and adaptive immune responses. In macrophages, nitric oxide is produced by inducible nitric oxide synthase upon microbial and cytokine stimulation. It is needed for host defense against pathogens and for immune regulation.

The discovery of the L–arginine:NO pathway has proven to be one of the most important and exciting scientific developments of the last decade. This pathway is involved in a myriad of physiologic roles that range from the control of vascular tone and blood pressure to the modulation of skeletal muscle function.

Tetrahydrobiopterin and Nitric Oxide Synthase Recouplers
2020Generation of nitric oxide (NO) by the nitric oxide synthase (NOS) enzymes plays multiple signalling roles in every organ system, with crucial roles in the cardiovascular system, mediated by endothelial nitric oxide synthase (eNOS, encoded by NOS3) and neuronal nitric oxide synthase (nNOS, encoded by NOS1) in regulation of blood pressure, flow, oxygen ...
